With the development of electronic technology, intelligent simulation and computer network, electrical automation technology has developed rapidly. Electrical automation technology not only integrates the advantages of comprehensive technology, but also improves the stability of the whole system while realizing electrical automatic control. On the premise of rational use of electrical automation technology, it is necessary to comprehensively identify electrical automation technology. At present, we should fully understand the characteristics of electrical automation technology, the main points of industrial application of electrical automation technology, the innovative development of electrical automation technology, and support the continuous progress of electrical automation. This is also the main goal at present.
1 Basic characteristics of electrical automation technology
1. 1 completeness of electrical automation technology
Electrical automation technology is a comprehensive technology, involving a wide range, which is closely related to the actual electrical automation control work, especially the relationship with thermal power engineering, construction field and steel industry, which will form the characteristics of wide coverage and strong comprehensiveness of electrical automation technology, and it needs a certain comprehensive ability to fully grasp the essence of electrical automation technology.

2 practical application of electrical automation technology
2. 1 application of electrical automation technology in thermal power engineering
Electrical automation technology can realize the integration of boiler, machinery and motor (figure 1 is the electrical control system of motor) in thermal power generation project, which is beneficial to the control and management of thermal power generation project. Electrical automation technology can screen and check the hidden dangers and faults of thermal power projects, which can be effectively dealt with in the early morning of thermal power projects, reducing the failure rate and accident losses of thermal power projects. Electrical automation technology can realize the automatic operation of thermal power engineering, and can unify the three systems of management, operation and control, so as to realize the automation, barrier-free management, control and operation of thermal power engineering, improve management efficiency, improve operation accuracy and realize accurate automatic control of the engineering.
2.2 Application of electrical automation technology in iron and steel industry
An important symbol of building a modern iron and steel industry is the comprehensive application of electrical automation technology in the iron and steel industry. Based on electrical automation technology, the steel industry can improve the quality control of raw materials and realize the safety guarantee of steel production environment, which is an advantage that traditional management means and methods do not have. Electrical automation technology can control the quality of steel products. Through the automatic control of steel production process, details and technology, the efficiency of steel production can be improved and the deepening development of steel industry can be promoted.
2.3 the application of electrical automation technology in the field of construction
The application of electrical automation technology can monitor the power system in real time and digitally, effectively transmit the instructions from the control center to the system, and transmit the feedback information to the control center, so as to realize the "real-time, funny and continuous" management and control of the whole power system. Moreover, the use of electrical automation technology can improve the linkage of related building equipment and facilities, and the power distribution, fire fighting, lighting, air conditioning and other systems in the building can be integrated with electrical automation technology, which greatly improves the linkage effect of the system, and solves the problem that the elevator system can automatically adjust the speed according to the user's flow floor and automatically judge and identify the system in an emergency (water pipe rupture, fire, etc.). ), even if the emergency plan is preset, the emergency lighting system is turned on, the automatic sprinkler system is turned on, or in addition, the electrical automation technology has high safety, and there are certain risks in the building electrical system, personnel operation errors, changes in the working environment, and equipment failures may all lead to serious safety accidents in the power system. However, the use of automatic control technology can help the system to respond to abnormal situations in the work.
3 Bottleneck of current electrical automation technology
3. 1 Serious energy consumption.
As we all know, electrical engineering is a particularly energy-consuming technical project, because the development of electrical engineering can not be separated from the support of energy. However, the low energy utilization rate in modern life has seriously hindered the long-term development of electrical engineering, so electrical engineering must improve energy utilization rate on the basis of energy saving to ensure the development of electrical automation technology. Throughout the current industrial enterprises, both design and skills are still lacking in energy saving. This is an urgent problem for engineering designers to solve.
3.2 There are hidden dangers in quality
At present, many enterprises have such a misunderstanding that they attach importance to production results and ignore quality. The reason is also related to the late start of electrical automation in China, because both the management mechanism and the development model are not perfect enough, which also makes the development of the electrical industry stagnate. Nowadays, with the gradual improvement of people's safety awareness, attention to quality and safety has become the focus. For an enterprise, quality is related to its survival and elimination, especially for industrial enterprises with frequent quality and safety accidents. The quality and safety of equipment play a vital role in the development of enterprises.
3.3 Low work efficiency
The development of productive forces determines the production efficiency of enterprises, and it is also an important part that affects the efficiency of enterprises. Since the reform and opening up, China's electrical engineering and its automation technology have achieved good results. Of course, the inefficiency of red work can not be ignored. The main factors of low work efficiency are limited by productivity level, application method and application scope. Whether an enterprise can skillfully operate electrical engineering automation technology directly affects its economic benefits.
3.4 The unified standard of electrical engineering network architecture has not yet been formed.
Judging from the current development situation, it has become an inevitable trend to achieve a high degree of integration of electrical engineering and automation technology. Once a breakthrough is made, it will directly improve the production efficiency and accuracy of the industry. However, in order to get further development, we need to establish a unified network architecture first. Based on the differences between different enterprises and the lack of standardized program interfaces in the production of hardware and software equipment, a lot of information and data can not be shared, which will also bring some negative effects to the development of electrical engineering automation, which will eventually be very serious.
4 improvement strategy of electrical automation technology
4. 1 Pay attention to energy conservation awareness
In order to fundamentally reduce the energy consumption phenomenon in electrical engineering automation, we should raise the awareness of energy saving from the perspective of quality management and consciously apply the unified management of quality and energy saving. Specifically, the focus of electrical engineering automation energy saving lies in the management of transformers, such as selecting transformers with lower losses or improving transformer technology. In addition, all employees need to have a comprehensive understanding of quality, understand that only by constantly improving their technical ability can the quality of the project be guaranteed, and at the same time, in order to save energy, innovative spirit is needed, so as to better improve the design of electrical engineering and its automation.
4.2 Further strengthen quality management
No matter for any industry, quality is the last word, but for electrical engineering, in order to avoid safety accidents, we should pay more attention to the quality of the project, so enterprises should regularly train their employees in skills and professional knowledge, introduce professional management talents, and improve the flexibility of management and system as a whole. In addition, we should not only strengthen the quality management of electrical engineering construction, but also recognize its importance. First of all, the quality of materials used in construction should be strictly managed. Secondly, the materials needed for construction must be purchased by professional and technical personnel, and the materials entering the site should also be arranged for professional management personnel to conduct irregular spot checks to strictly ensure the quality of construction materials.
4.3 Building a unified and independent platform
A comprehensive investigation and study of enterprise users is helpful to draw up the initial goal before design, and to maintain the effective operation of the project and the integrity of the work when determining the scheme and budget estimate; In order to reduce operating costs, a unified and independent system is established according to the needs of end customers and commercial projects. The reason for the high cost pressure is that there is no unified operating platform and it is not universal. This is because electrical engineering and its automation are built by enterprises according to their own conditions. Therefore, the implementation of electrical engineering and its automation needs to be established in a good environment and a unified and independent automation platform should be created.
4.4 Establish a unified electrical automation network architecture.
(1) China should issue the implementation standards or guidelines for the unified network architecture of electrical engineering and its automation industry as soon as possible, and at the same time take corresponding legal forms to assist the implementation of the network architecture, so as to ensure the unification of the network architecture of electrical engineering and its automation production equipment as soon as possible under the guidance of national standards.
(2) The existing electrical engineering and its automatic production equipment should also be upgraded in network architecture to avoid the occurrence of information asymmetry, so that they can really enjoy data information under a unified network architecture.
5 concluding remarks
The vitality of electrical automation technology lies in structural integrity. At present, electrical automation technology has achieved wide adaptability in various industries and has become the main technology in related industries, thus improving the research level of electrical automation technology in order to better grasp the core of electrical automation technology. We should start with understanding the characteristics of electrical automation technology, explore the application points of electrical automation technology in thermal power, steel, construction and other industries, and further grasp the electrical automation technology from the technical key and development trend.

Abstract of electrical engineering students' thesis 2:
With the further implementation of the reform in the electric power field, the requirements for the operation of electrical equipment have also been improved. To strengthen the safe and stable operation of electrical equipment, we must proceed from reality and effectively solve the faults of electrical equipment, which requires the scientific application of corresponding maintenance technologies. This paper mainly analyzes the common faults and their causes in electrical engineering, and then discusses the application of fault maintenance technology in detail, hoping to promote the normal operation of electrical equipment through this theoretical research.
Key words:
Electrical engineering; Fault; Maintenance technology
Equipment failure is very common in electrical engineering. Under the influence of many factors, there are many failure problems in electrical engineering. It is very important to find the cause of the fault and solve it pertinently. Through the study of common faults in electrical engineering, it can provide theoretical basis for solving practical fault problems, thus better ensuring the good development of electrical engineering.
1 Common faults in electrical engineering and their causes analysis
Under the influence of different factors, electrical engineering will have different faults, which will have a great impact on the normal operation of electrical equipment. In electrical engineering faults, unbalanced three-phase electricity consumption, poor neutral grounding and a large number of electrical equipment damage are prominent, which are also common fault contents. In the design of electrical engineering, in the specific construction and installation process, the common phenomenon is poor midpoint contact. Some people didn't notice this during the construction, which caused serious losses [1]. For example, when the office building is hot, the TV sets, tape recorders and other electrical equipment in use are damaged a lot. Through inspection, it is found that the normal value of wires and cables is 380V, while the A-phase voltage is 280V, and the load neutral point voltage is 70 V, which is mainly caused by unbalanced three-phase electricity consumption and poor neutral point contact. Among electrical engineering faults, relay protection faults are more prominent, mainly because the materials used are not up to standard and the quality does not meet the actual requirements. Some electrical relay protection failures are mostly affected by the factors of product quality and materials, so there are many fault problems, which make the relay protection device in a dangerous state and have a great influence on the improvement of product actual performance. The occurrence of electrical engineering faults is more prominent in poor contact and repeated grounding faults. In the actual operation process of the electrical system, it is easy to cause potential safety hazards when operating with faults. Affected by design factors, the fault management of voltage transformer is unscientific and easy to occur. When in use, the voltage keeps rising, resulting in the phenomenon of circuit load shedding and short circuit. In the electrical engineering fault, the equipment did not respond after pressing the equipment start button, and the motor did not rotate after the equipment started, resulting in buzzing and the motor turned in one direction [2]. These faults have many influences on the normal operation of actual electrical equipment. For the above electrical fault problems, it is necessary to make a detailed analysis and find targeted methods to deal with them.
2 the implementation of electrical engineering fault maintenance technology
Scientific selection should be paid attention to in the application of electrical engineering fault maintenance technology. Combined with the actual situation, the author puts forward several measures for the application of electrical engineering fault maintenance technology, as follows:
First, the application of intuitive method in electrical engineering fault. There are many methods for maintenance and judgment of electrical engineering faults, among which intuitive method is commonly used, which mainly detects and judges electrical engineering faults through vision and smell, and is commonly used without corresponding detection equipment. When applying this method, the observer needs rich experience, so as to play the role of intuitive method [3]. If there is a yellow part or burning smell in the relay protection device, it can be intuitively judged that the equipment is faulty, which can also provide favorable conditions for solving specific fault problems.
Secondly, the application of electrical engineering troubleshooting methods. When electrical engineering fails, it can also be effectively handled by dismantling. In the application of this method, the influence between the electrical appliances in the series circuit is mutual, and there is no current after the electrical appliances arbitrarily exceed the limit. In parallel circuit, the electrical appliances work independently, and there is no connection between them. Removing one of them will not affect other appliances. This can not only protect electrical appliances, but also be used as a method to find faults.
Third, strengthen the safe use of electricity. In order to ensure the normal implementation of electrical engineering, we must pay full attention to the setting of electricity consumption. The common problem of temporary electricity consumption in construction is that the grounding body is buried without specification. TN-S power supply system is adopted in the temporary power supply system, in order to effectively ensure the effective solution of faults in power engineering, so that no current passes through the PE line under normal circumstances, specifically carrying fault current and effectively protecting the device. It is also necessary to set up leakage protectors and adhere to the principle of three-level protection.
Fourthly, the application of electrical engineering fault replacement method. In the aspect of fault solving, we should pay full attention to it from many aspects and scientifically apply the substitution method, which is widely used in the maintenance technology of relay protection devices. It has played a positive role in solving the fault of microcomputer protection device. In the application of substitution method, mainly when the microcomputer protection device fails, the maintenance personnel will replace its device and apply a new microcomputer protection device [4]. When using microcomputer equipment, we should pay full attention to whether the normal plug-in and replacement plug-in models are the same, so as to ensure the full play of the equipment.
Fifthly, the application of electrical engineering fault parameter comparison method. In the process of specific fault maintenance, the application of parameter comparison method plays a positive role in solving the relay numerical problem in relay protection devices. In practical application, when the relay value is normal and there is a fixed index standard, the abnormal value will change, so that the cause of the fault problem can be found under the parameter comparison, so as to solve it pertinently. The application of this method will promote the solution of electrical engineering faults.
3 Conclusion
In a word, we must attach importance to scientific application methods to solve fault problems in electrical engineering. In people's lives, the demand for electricity is increasing, and the overall quality assurance of electrical engineering is becoming more and more important. Through the theoretical research of this paper, it can play a positive role in promoting the troubleshooting of electrical engineering, thus ensuring the good development of electrical engineering. I also hope that the theoretical research of this paper can enlighten the work of practical staff.
