With the continuous development of China's society and rapid economic growth, it has injected a steady stream of vitality into China's power engineering in recent years, especially the application of power system automation technology, which has pointed out a new development direction for it. As the core part of power engineering development, the effective application of power system automation technology has greatly enriched the development of power engineering. In recent years, the efficiency of power engineering has been improved year by year. Based on this, it is necessary for electric power enterprises to pay more attention to automation technology, keep up with the development of the times, and effectively optimize and update it to maximize its value.

In recent years, China has made some progress in science and technology, which greatly encouraged China electric power enterprises to achieve rapid development. As a modern technology, automation technology has been widely favored by the society and has been effectively applied to the operation of power system, laying a solid foundation for its operation efficiency. Nowadays, as the key link of power engineering, how to strengthen the application effect of power system automation technology has been widely discussed by residents. In view of this phenomenon, China's electric power enterprises should improve their automation technology according to the present situation of scientific and technological development.

First, the application advantages

Although China's power system automation technology is in the primary development stage, in recent years, with the continuous development of science and technology, it has provided a power source for its development and made it progress to a mature stage. The main principle of power system automation technology is based on the comprehensive application of information technology, electronic processing technology and network communication technology, so that it can effectively act on the power grid system and help the power system to operate and maintain. Usually, as a common automation system in power engineering, it is necessary not only to strengthen the effective application of control and equipment power supply system, but also to express it scientifically in the updated information system to ensure the implementation of automatic monitoring system. For the traditional power operation mode, the advantages of modern automation system technology are more prominent, which can not only ensure the operation efficiency of the system, but also ensure the safety. In other words, the electronic system automation technology can complete the basic operation through the power system, which not only liberates manpower to a great extent, but also avoids the potential safety hazard caused by human error. The effective application of information technology can make the operation of power grid system under comprehensive monitoring and greatly reduce the frequency of safety accidents.

Second, the general situation of development

(1) Substation

As an important part of power system, the automation of electronic system can effectively affect the operation and maintenance of substation. When carrying out practical work, first of all, technicians should not only master and understand the basic information of all aspects of the substation, but also accurately reflect it on the equipment to ensure the operation effect of the substation to achieve the expected goal. Secondly, based on the operation principle of the substation, technicians should effectively discuss its actual working state, so as to effectively adjust the substation automation technology, make it play its greatest value in the operation of the substation, and realize the optimization and upgrading of the substation work. Finally, technicians should attach great importance to substation information and integrate it effectively, so that power grid automation can effectively affect the operation effect of substation and ensure the efficient operation of power system.

(2) Power distribution system

In modern power distribution system, optical fiber technology is widely favored. Compared with other traditional technologies, optical fiber technology has the outstanding characteristics of high speed and high stability in the transmission process, and has been effectively applied in power systems. However, as far as the current development is concerned, optical fiber technology has higher requirements for information technology and higher costs, so there are still some difficulties in the promotion process. As a common modern power distribution technology, communication technology can not only help the normal operation of power system, but also its transmission rate can be comparable to that of optical fiber technology, so it has been widely favored by power enterprises and applied in power distribution system.

Third, practical application.

(A) simulation technology

As an important part of power engineering, if the application effect of simulation technology can not reach the ideal goal, it will not only lead to the failure to effectively reflect the function of motorization technology, but also hinder the operation of power system to a great extent. Aiming at the relevant data in power system, simulation technology can not only effectively analyze it, but also effectively avoid the shortcomings in manual analysis of information, strictly control the information, and make it accurate and qualitative, thus avoiding the adverse consequences caused by decision-making mistakes. In addition, the simulation technology can not only help the power system to allocate resources effectively, but also follow the principle of rationality and comprehensively study the information in the system, so as to maximize the economic benefits of power enterprises and ensure their working efficiency to reach an ideal state. At the same time, in the specific operation process of the power system, the staff can use the simulation technology to monitor its working state in real time, effectively grasp its operation effect and fully reflect its stability. It also ensures the timeliness of problem handling to a great extent. Once the disadvantages are found, the staff can adjust the power system in time according to the data obtained by simulation technology to stabilize its working state.

(2) Computer technology

With the continuous development of the times, as a product of scientific and technological development, computer technology has spread to all aspects of China's social development. Power engineering has integrated computer technology into the operation of power system in the early stage of development, which has made the operation of power system more stable to a great extent, promoted the effective development of power enterprises, raised their work efficiency to a higher level and guaranteed their economic benefits. Computer technology can not only manage and develop different resources, but also constrain the whole power system process, make it run under all-round monitoring and strictly control its working state, so as to ensure the smooth development of various processes in the power system. The effective application of computer technology can not only reduce the workload of personnel, but also alleviate the negative impact caused by human error to a great extent, which plays a vital role in improving the overall power supply efficiency.

(3) Intelligent protection technology

In a specific working state, intelligent protection technology can not only effectively analyze the database stored in the power system, but also manage and develop it according to the application mode of different resources. Nowadays, with the development of science and technology, intelligent protection technology not only integrates computer technology, but also makes rapid progress on the basis of automation technology, which not only keeps the operation of power system stable to a great extent, but also makes the economic benefits of power engineering reach expectations. At the same time, the intelligent protection technology can also effectively detect the equipment running in the power system and feed back its working status to the technicians, ensuring the real-time feedback, making the equipment maintenance work smoothly and greatly reducing the losses caused by equipment failure. In the process of using intelligent protection technology, technicians should analyze the running state of power system in real time and make adjustments, so that it can maintain the daily work of power system and help power enterprises achieve longer-term development.

PCL technology

As a modern operation technology, the application effect of PLC technology in power engineering has been widely valued by the society. With the development of the times, people pay more and more attention to the concept of energy saving, and the effective operation of PLC in power engineering has greatly alleviated the serious disadvantages of power system, so that the concept of sustainable development can be implemented. In the actual operation of power system, PLC will generate a certain amount of electric energy, which can be effectively stored and reused by technicians [4]. PLC technology not only has electromechanical touch control technology, but also combines the advantages of computer technology and information technology, which can not only realize the automatic operation of power system, but also help the editing of programs to a great extent, so that the order can be fully reflected and lay a solid foundation for the stability of power system. The effective application of PLC technology can not only alleviate the serious power consumption problem, but also realize the value of the concept of energy saving and emission reduction to the maximum extent, and can also promote the sustainable development of power enterprises to a great extent, bringing huge economic benefits to them.

Fourth, conclusion:

In short, although China's power engineering has developed by leaps and bounds in recent years, there are still some problems in the operation of power automation technology. Power enterprises should base themselves on the operation of power system, not only control the effective operation of substations, but also make the distribution system scientific. Technicians should attach great importance to simulation technology, strengthen the application effect of computer technology, make intelligent protection technology play its greatest value in power engineering, provide guarantee for the operation of power system, and further promote the all-round construction of power engineering in China.
