1, Introduction
With the continuous innovation of science and technology, automation technology is more and more widely used in electrical engineering projects. Electrical engineering and automation technology began to be applied in agriculture and industry and other fields. As a new technical means, its application value is constantly improving, and it has begun to penetrate into all aspects of people's lives. Compared with foreign countries, China's electrical engineering and automation technology started late, and there is a considerable gap in both technical level and application effect.
Electrical engineering and its automation technology is a new technology that integrates automation technology, computer technology, mechatronics technology and so on. It first appeared in the 1970s, but it didn't develop well at that time due to the lack of funds and technology. After 1990s, this technology has developed rapidly, but there are still many problems. It is of great significance for China's economic development to strengthen the research on current electrical engineering and its automation technology, find problems and carry out targeted rectification, and constantly promote the development of electrical engineering and its automation [1]. This paper mainly discusses the problems existing in electrical engineering and its automation technology, and puts forward corresponding solutions to promote the rapid development of high-tech and industrial intelligence fields in China.
2. The application scope of electrical engineering and its automation.
2. 1, Application in Power Grid Dispatching
With the improvement of people's living standards, electric energy plays an active and important role in daily life and industrial fields. In power system, power grid dispatching will affect the stability of power system operation. Electrical engineering and its automation technology realize automatic scheduling in power grid scheduling, which can not only save the network construction cost, but also ensure the safety of power grid operation and improve the efficiency of power grid operation. Real-time monitoring is carried out in the process of power grid dispatching, and the obtained data is fed back to the dispatching center. The dispatching center can analyze the received feedback data and give early warning of the problems in time, so as to improve the security of the power grid, avoid the overload of the power grid and ensure the stable operation of the power system.
2.2. Application in Substation
Electrical engineering and its automation technology can be applied to substations. At present, many substations in China have realized the application of automation technology. The application of substation automation technology can change the traditional manual operation mode, thus saving manpower, material resources and expenditure costs. At the same time, it can prevent people with unclear professional knowledge and poor professional quality from mistakenly controlling the substation and causing a series of fault problems. Automatic substation also has the functions of self-diagnosis and self-protection. When there is a problem in the substation, the location of the problem and the wrong data can be fed back to the dispatching center in time. The dispatching center will send relevant maintenance personnel to repair it. When the substation detects wrong data, it will be sent back to the dispatching center, although it will not cause related fault problems, and it can make an early warning.
3. Problems in electrical engineering and its automation.
3. 1, energy saving
Electrical engineering and its automation technology have been applied in various fields of China's industry, which has promoted the continuous improvement of China's industrial intelligence level, and all kinds of advanced equipment have been widely used. However, problems such as energy consumption also follow. In the process of related equipment operation, because the technology is not up to standard, it is easy to cause the overload phenomenon of electrical equipment in power system operation, shorten the service life of power supply equipment, greatly increase energy consumption, and fail to achieve the ideal effect of energy saving in electrical engineering, which is not conducive to the sustainable development of China's industry.
3.2. Integration
Compared with foreign countries, China's electrical engineering and automation technology started late, so the integration is not high. At present, the integration technology of electrical engineering is still in the development stage, and it can not be well applied to the field of electrical engineering. The development level of integration technology is not high, which easily leads to obstacles in the process of information sharing, communication and transmission. There is no effective connection between different systems, which makes the function of equipment imperfect and greatly hinders the application of automation technology in electrical engineering projects. At present, there is no unified standard for electrical automation system in China. For different enterprises, the architecture of electrical system is different, even for different industries, the architecture of the system is also very different. The compatibility of electrical automation equipment is not very good, and there is no interoperability between various fields. The different standards of hardware and software equipment have also brought troubles to manufacturers and affected the enjoyment of resources in the industrial field.
3.3, quality
In the field of electrical engineering and automation, there is no unified standard for the construction technology and quality of electrical systems in China. The professionalism, professionalism and enthusiasm of construction workers are generally not high, and there is no detailed inspection and operation in the implementation process, which can not guarantee the quality and safety standards in the construction process. The related enterprises did not pay enough attention to this, which led to the quality problems of electrical engineering and automation equipment and systems. This will not only increase the cost of enterprises, but also threaten the life and health of construction workers and reduce the competitiveness of enterprises in the market.
4. Electrical engineering and its automation strategy.
4. 1, optimize energy-saving equipment
In the actual operation of the electrical system, resources are wasted from time to time, so it is necessary to do a good job of energy conservation and emission reduction. R&D personnel should vigorously develop new energy-saving equipment and combine the electrical field with the artificial intelligence field. In the actual operation of the electrical system, the transformer with smaller resistance can be selected to achieve the purpose of energy saving and emission reduction. At the same time, relevant departments should build a reasonable equipment operation system to avoid overload during operation, resulting in short equipment life and excessive energy consumption. In addition, the equipment should be inspected and maintained regularly to ensure the maximum utilization of energy when the equipment is used. We should make full use of clean and pollution-free renewable energy such as solar energy, prevent excessive consumption of traditional energy in China, solve energy consumption problems to the maximum extent, avoid energy waste, improve energy utilization, realize energy conservation and emission reduction, and create a green production environment [2].
4.2, improve the degree of integration
In order to improve the integration of electrical system, we must first increase the investment of funds and corresponding R&D personnel. Encourage R&D personnel to actively participate in the construction of electrical system integration. Secondly, learn from foreign advanced technology, cooperate with foreign related enterprises, learn from their experience in integration construction and take its essence. Finally, according to the current level of integration construction in China, a set of practical unified standards is formulated.
4.3, strengthen quality control
In electrical engineering and its automation construction, the most important thing is to pay attention to solving quality problems. First of all, it is necessary to improve the professional and technical level of operators and constructors, conduct skills training courses on a regular basis, hold corresponding skills examinations, and issue skills certificates to those who pass the examinations. Only those who have obtained skills certificates are qualified to operate electrical equipment, which can ensure the smooth progress of electrical construction. Secondly, the relevant departments should strictly examine the raw materials used in the electrical construction process and strictly supervise the procurement process. Resolutely abandon unqualified raw materials, set up professional management personnel, and strictly control the construction materials entering the site [3]. Ensure that the construction materials meet the national standards and the construction process is safe and orderly. Finally, the monitoring system should be applied to electrical automation control technology. The monitoring system can monitor all the parameters of the whole equipment platform, send information to the main console in time if there are quality problems, and send maintenance personnel to deal with them in time to improve the operation efficiency of the equipment. The monitoring terminal can remotely monitor and control the equipment through the login platform, and the use of electrical equipment is more intelligent.
5. Conclusion
With the continuous improvement of China's scientific and technological level, electrical engineering and its automation technology have been widely used in various fields in China and played an important role in promoting industrialization. Major universities in China have set up electrical engineering and automation majors in order to train relevant technical personnel and better serve the field of electrical engineering in China. Although China's electrical engineering and automation technology started late compared with foreign countries, there are many loopholes. However, as long as the relevant personnel deal with these problems properly and increase the investment of R&D personnel, China's electrical engineering and its automation technology will usher in a leap-forward development in the future and build a unique electrical engineering project system in China.
