1 main technical problems in power engineering of distribution network
1. 1 unscientific use of reactive power compensation equipment
In the technical application of power engineering in distribution network, there is also a very important technical problem, that is, reactive power compensation equipment, because it is easy to consume electricity in the process of power transmission, and reactive power compensation equipment can just reduce the power consumption problem in the process of power transmission and ensure the continuous and sufficient supply of power in distribution network. Harmonic interference is the natural enemy of reactive power compensation technology, which will interfere with reactive power compensation equipment and make it unable to work normally. Therefore, it is necessary to use reactive power compensation equipment scientifically.
1.2 transmission line is damaged by external force.
During the construction of power distribution project, many of the power distribution we see are supported by telephone poles and then transported by air. Most of these power supplies are radial single-ended power supplies. Nowadays, due to the economic development, various residential areas, industrial areas and commercial areas have mushroomed, and these huge power consumption systems have caused great pressure on power engineering. Many people connect electricity directly from the telephone pole, so the connected wire itself is temporary, unsustainable and prone to leakage and short circuit. In addition, many times the wires you see are like cobwebs, criss-crossing and completely disorganized. There are many distribution lines in many construction areas, which will cause external damage to the lines. Exposed lines near chemical plants will be damaged by air and environmental pollution around chemical plants, leading to accidents.
1.3 unreasonable power distribution
The distribution of power supply is a global problem related to the coordinated operation of power engineering in the whole distribution network. If the power distribution is unreasonable, it will lead to various power situations in the whole power transmission process. At present, the power distribution mainly presents the following status quo: the distribution area and pipeline concentration area of various domestic applications are intertwined, which is easy to affect the surrounding living environment or natural environment. When building a substation, the location of the substation is too far away from the location of the power supply, resulting in a long transmission distance and inconvenient power transmission. Another problem is that the power supply equipment of power distribution project is not sufficient and powerful enough to ensure adequate power supply, which will easily affect the coordinated and efficient operation of the whole power distribution system.
.
1.4 flashover caused by dirt accumulation
The flashover problem is a technical problem that threatens the power engineering of distribution network due to external factors. This problem is mainly caused by the long-term exposure of distribution lines to the air. After a long time, all kinds of dust and dirt will accumulate. After these dust and dirt accumulate to a certain extent, they will contain a certain amount of salt. If these salts meet with rain or snow again, the salt on the dirt will be reflected when it comes into contact with the air. Coupled with the pressure generated by power transmission in the line, serious flashover will occur in the distribution line. Flashover leads to serious polarization of single-phase voltage and two-phase voltage, and the two-phase voltage rises, resulting in abnormal operation of distribution system. In addition to flashover caused by pollution, there is also phase insulation flashover, which will cause two-phase grounding and short circuit.
2 distribution network power engineering science and technology measures
Power distribution project is a national project that benefits people and plays an important role in human society. Efficient and scientific distribution engineering will promote the great development of human society. However, there are many problems in the application of distribution engineering technology in China at present. How to improve the science and technology of distribution engineering and how to establish an efficient and sustainable distribution system requires scientific and effective methods to solve the technical problems in the distribution system to ensure the efficient operation of the distribution system.
2. 1 Reasonable power distribution
Because power distribution is a crucial technical problem in power distribution engineering. Therefore, to solve the problem of uneven power distribution, it is necessary to carry out reasonable power distribution to make the power supply work efficiently. How to distribute power is reasonable? First of all, we should sort out the lines and plan the route of each line to avoid the phenomenon of mixed lines and staggered power grids. Secondly, when building a substation, the distance between the substation and the power supply should be minimized, and the substation should be built around the power supply. Finally, it is necessary to equip the distribution power project with sufficient power supply equipment to ensure adequate and continuous power transmission of the power grid project.
2.2 Scientific use of reactive power compensation equipment
Reactive power compensation equipment can ensure the safe and reliable operation of power engineering in distribution network. However, when the reactive power compensation equipment is used unscientific, it is easy to be disturbed by harmonics, which leads to the failure of the distribution system. Therefore, when using reactive power compensation equipment, we should first understand and master the power supply system, and then choose reactive power compensation equipment according to the needs of the power supply system. When the power supply system and reactive power compensation equipment are matched, if there will be harmonic interference, then we need to install monitoring accessories.
2.3 Comprehensive management of external conditions
In view of the external technical problems and various flashover problems in power distribution, comprehensive methods should be adopted to deal with them. In the process of power transmission in the distribution system, it is necessary to check whether the lines are crossed and overlapped, and whether normal and scientific contact information is carried out. When setting the lines, try to avoid large construction sites and avoid serious damage to the lines. In order to solve the flashover problem, we can also take technical measures such as drilling casing and adding anti-pollution cover, which not only reduces the accumulation of dirt, but also ensures the normal transmission of power.
2.4 Install lightning protection equipment.
In the process of power transmission, it is often affected by lightning, resulting in various power problems. For example, there is a local overvoltage in the line. Therefore, lightning protection equipment must be installed in power engineering of distribution network, and lightning protection equipment must be installed where lightning protection effect can be exerted. It can not only avoid lightning strike, but also avoid overvoltage problem, which provides a guarantee for the safe and stable operation of distribution system.
3 Conclusion
In a word, with the popularity of electrical appliances and the rapid development of high technology, any aspect of our lives has reached an unprecedented level of dependence on electricity. Power technology has assumed the powerful protector of the whole distribution project. In order to ensure the reliable operation of distribution engineering, it is necessary to make up for the problems existing in distribution by using high technology and scientific management. Only when technology guarantees the project, can the project better provide us with sufficient and lasting power demand.

1 overview
In recent years, China's power industry has developed rapidly and the pace of reform has gradually accelerated. Electric power industry, especially in the development of national economy, plays a more obvious and prominent role, so it has become a pillar industry of China's national economy. In addition, the rapid development of power enterprises also puts forward higher requirements for power engineering construction. In order to further standardize the management of power technology projects, we should find out many problems existing in the development of power engineering in time and find out more reasonable solutions.
2 power engineering information management
As far as China's power engineering projects are concerned, with the development of project planning, formulation and implementation activities, a large number of information related to power projects, such as reports, contracts, photos and drawings, will appear. In this way, relevant personnel will collect, process and file, which is beneficial to the control and management of power projects. The information management of many power projects in China mainly refers to the scientific and reasonable management of the whole life cycle of power projects, and also refers to the collection, processing and processing of all kinds of information.
A large number of practices show that the information management of power projects will have a great impact on the efficiency and quality of the whole power project management. Therefore, how to manage the information of power project life cycle scientifically and reasonably has become the most important link in power project management. However, if computer technology is applied to the information processing of power projects, it can provide more scientific information management concepts, technical platforms and reasonable solutions for the planning, design and control of power project information management systems.
(1) Information management principle of electric power industry. For information management, it is mainly related to many factors, such as information resources, technology, various staff involved in construction, etc. It is also a management activity involving many factors and disciplines. In fact, the information management of power projects is a management activity with high technical requirements, so it needs a variety of technologies and management means. The following is an in-depth analysis of many principles of power project information management:
Principle of information appreciation: information appreciation refers to the increase of project information or the great improvement of the efficiency of information activities. To increase the content of information, we must rely on the collection, organization, processing and sharing of information in order to achieve it finally.
Synergy principle: For information management, by providing and developing information, such as the infiltration and activation of information to social activities, we can give full play to the role of information resources. This can not only save more social resources, but also greatly improve its work efficiency, win greater benefits for enterprises and ensure better social development.
Market regulation principle: the information management of power projects is directly regulated by the law of market development, mainly in two aspects: on the one hand, the price of information products is regulated by the law of market; On the other hand, various elements of information resources will also be regulated by market rules.
Service principle: Compared with other management processes, information project management shows strong service. For the whole process, method and purpose of power project information management, we should focus on the needs of users and play its role by serving users.
(2) Basic characteristics of information management of power projects in China: the main functions of information management include planning, leadership and control; And various activities organized by the main management objects; The main purpose of management is to achieve organizational goals, so it should also be possessed in information management. However, as the information management of the electric power industry is a specialized industry management, it has its unique characteristics, such as: it must be combined with the electric power enterprise system, and the equipment and various personnel information must be combined together. However, it is to gather all the information together, so that information can be used as a resource and information resources can be enjoyed. In addition, it can also enable power managers to grasp the dynamic information of relevant equipment and personnel in time to ensure the normal operation of the power system.
3 power engineering project information management system analysis
For the information management system of power process projects, the key is to provide corresponding information for managers, related personnel and some unexpected departments of power enterprises. The operation of the system provides reliable information basis for the development decision-making of power enterprises, and can also serve the planning, organization and control activities of power enterprises. For the electric power information management system, it is an information service that provides, collects, processes and uses a large amount of project information to the management department within the enterprise. Taking the intelligent inspection information management system of substation as an example, this paper analyzes it. The inspection information management system mainly uses "bar code" as equipment identification. At the same time, it will also install a "barcode" on each testing device. For the internal storage function, you can set a specific code to identify the running state and parameters of the equipment. In this way, the patrol personnel of electric power enterprises can conveniently and conveniently collect the corresponding data information on the site where the equipment is running. Because of its convenience and operability, the security patrol system is more suitable for field use and can better solve the complex data entry work. Therefore, it has played a great role in improving equipment maintenance level and reducing data input. Once the running state of the equipment needs to be overhauled, the performance of the equipment needs to be analyzed, and relevant information can be retrieved from the database at any time to make the historical running state of the equipment clear at a glance.
3. 1 The substation intelligent patrol information management system consists of multiple hardware, such as RF equipment identifier, client computer, network server, patrol system, etc.
3.2 Analysis of the characteristics of substation intelligent inspection information management system
Inspection routes are reasonably classified according to different majors and departments; Compiling inspection contents must be flexible; Combine equipment and parts to organize all inspection routes at different levels; Two modes, namely, inspection and spot check; For inspection routes, you can set the inspection items as complete. In addition, in order to facilitate inspection personnel to input information, the system can set up a variety of inspection items, such as observation, recording, temperature measurement and so on.
Analysis of information processing and statistical function of power system server software;
First, information inquiry. This function is an indispensable part of power system information processing. Combining various query functions in various ways is beneficial to processing and analyzing information, so as to obtain the desired results. The most commonly used query methods are mainly work query, abnormal query and missing query.
Secondly, the report function. This function is to make a relatively perfect report when designing the power system, and at the same time, users can customize the required report according to their actual needs.
Third, the defect management function. This function enables the system to search by patrol personnel, patrol time and equipment. , which is more convenient for patrol personnel to count various problems of equipment. In addition, the problem of equipment defects can also be transferred to other systems, which is beneficial to the combination with others.
Finally, check the statistical function. This function is to facilitate the statistics of the work of inspectors, so as to better assess the actual work of inspectors. Its contents mainly include the following points: line statistics, anomaly statistics, working hours statistics and so on. Among them, abnormality statistics refers to whether there is any abnormality in power equipment; For man-hour statistics, it is to count the inspection time when inspectors arrive at the site and the time when they arrive at the inspection point.

Generally speaking, the power industry is the leading industry that affects China's international livelihood, especially in promoting the development of national economy. In the future development of China electric power industry, it is bound to develop very rapidly. However, due to the characteristics of large investment and heavy tasks in power construction projects, a large number of new technologies and processes need to be applied. In recent years, the state has put forward higher requirements for the quality, duration and safety performance of power engineering. Therefore, China's power projects must keep pace with the times and finally realize modern management. In addition, we can learn from some foreign advanced technologies and management methods to make the power system run safely and efficiently. The extensive application of information management system in power projects can not only lay a solid foundation for project management, but also greatly improve the level of project management.
