Power system is an important guarantee for the rapid economic development. With the development of computer technology and electronic intelligent technology, the development of power switchgear is more suitable for social needs. The intelligent development of electronic switchgear is conducive to promoting the stability and safety of electric power equipment, and can better complete the operation of electric power equipment. Moreover, the development of power switch cabinet can promote the attention and application of new technology in power enterprises, improve the problems and shortcomings of power switch cabinet by using technology development, and realize simpler operation of power switch cabinet by using intelligent control technology. The intelligent controller of power switch cabinet, as its name implies, is to improve and perfect the traditional power switch cabinet. Intelligent control technology (computer technology, telecommunication communication technology, etc.) is applied to the controller of power switch cabinet to realize the automation and intellectualization of power switch cabinet controller, save economic cost and improve power at the same time. Operational safety and stability of the controller. The intelligent controller of power switch cabinet generally includes central detection and processing module, LED display module, protection module and functional module. The intelligent controller of power switch cabinet mainly controls the monitoring of current and voltage signals in power system, and then carries out relevant data processing and transmission to realize the automatic control and operation of power system.
The intelligent controller audit of power switchgear has the following advantages. Because of the use of computer technology and related information digital technology, the intelligent controller of power switch cabinet is mainly composed of integrated circuits, and the functions of intelligent controller are more perfect (integrating measurement, protection, control and recording functions). At the same time, digital communication technology can be used to realize information transmission and integration. The advantages of digitization and digitization are obvious. Intelligent controller of power switch cabinet works by using pre-programmed control program of technicians.
Therefore, in order to avoid the problem of intelligent controller and affect the work efficiency of power system, technicians can install well-programmed intelligent functional software in advance, and set up over-current protection for intelligent controller. The protection program dynamically links up the protection film in the loop network and ensures the dynamic cooperation between the two, so that the intelligent control of the controller can be realized. In case of failure and problem, intelligent controller can achieve the purpose of emergency control and protection. The main reason is that the size of intelligent controller of power switch cabinet decreases, which is convenient for transportation and operation. However, thermostatic element the function of intelligent controller (monitoring, protection, self-inspection, etc.) is more powerful and reliable, which can promote the continuous development of power system.
The main function of intelligent controller of power switch cabinet is to protect the line safety of power system.
Therefore, intelligent controller is the most basic device and the most core device in power system. When technicians program the intelligent controller of the power switch cabinet, they must ensure the optimization and perfection of the intelligent control and protection function of the controller, so as to realize the functions of automatic monitoring and intelligent operation of the intelligent controller of the power switch cabinet. The automatic monitoring function of intelligent controller of power switch cabinet is the basis to ensure the accuracy of data.
The design of automatic monitoring function of intelligent controller is mainly realized by using sensors with high sensitivity. Sensors can effectively sense the changes of current, voltage and other data signals in power system, and then timely monitor and feedback changes beyond the standard range according to the established procedures, which can effectively ensure the stability and safety of power system operation. Computer technology and data processing technology are the basis to ensure the intelligent operation of power switchgear intelligent controller. The principle of intelligent control operation of intelligent controller is to use some computer software and data processing program to receive and process information data, and then operate purposefully according to the actual situation. The main function of the intelligent controller of the power switch cabinet is to realize the automatic monitoring of the power system. The automatic monitoring of the intelligent controller is mainly to monitor the following aspects of the power system. Circuit monitor. Electric power workers are well aware that the circuit is a very important electronic component in the power system.
If there are internal faults in the circuit, the efficiency and stability of power system operation will be greatly affected. Therefore, effective measures must be taken to prevent the occurrence of circuit breakdowns. The automatic monitoring of intelligent controller of power switch cabinet can monitor the degree of hoe wear, magnetic field structure and the number of switch times of current magnitude and magnitude of circuit, and can process and analyze according to the data information monitored, and then make use of the circuit.
The state and service life are used to judge and ensure the safe and stable operation of the power system. Capacitance parameter monitoring. The intelligent controller in power system not only monitors current and voltage, but also monitors an important parameter change: capacitance parameter change. Because the changes of capacitance parameters exceed the standard range, the circuit will also operate abnormally. Therefore, the intelligent controller of power switch cabinet should effectively monitor the switching capacitance and the switching capacitance by using the automatic monitoring function, and implement effective processing operation according to the monitoring analysis results to ensure the safety and effectiveness of the circuit capacitor. Self-monitoring. The intelligent controller of power switch cabinet can not only monitor the fault of power system, but also monitor its own operation system. That is to say, when a structural element of the intelligent controller of power switch cabinet is in abnormal condition, the automatic detection module of the intelligent controller will play a role in time. It can effectively detect the corresponding chips and communication circuits that are in trouble, ensure that the fault points are found in time, and facilitate the technical personnel to repair the intelligent controller. Intelligent operation of intelligent controller of power switch cabinet mainly uses operation module and automatic monitoring module to cooperate with each other to achieve the purpose of intelligent operation function. Automatic monitoring mainly monitors the parameters of circuit breaker, closing voltage and capacitance level in power system. When the monitoring data is processed and analyzed, once the abnormal situation is found, the alarm will be issued, and then the central detection and processing module in the controller will issue corresponding operation instructions according to the alarm information to realize intelligent operation. Therefore, when adjusting the synchronous closing times of circuit breakers, technicians should ensure the synchronization and accuracy as far as possible, reduce the no-load probability of the system, realize the effective protection of the safe operation of circuit breakers and power systems, further ensure the working conditions of electrical equipment components in the power system, and prolong the service life of the equipment. Nowadays, most of the intelligent controllers of power switchgear in our country use general CPU, single chip computer and other components. This type of intelligent controller has high production cost, relatively complex circuit, which is not conducive to wide use and promotion, and can not effectively realize the performance optimization of intelligent controllers of electronic switchgear. Relevant professional researchers must increase the research depth of intelligent controller, devote themselves to improving the performance of intelligent controller of power switchgear, and promote the development process of intelligent controller in China. Therefore, researchers and designers must pay attention to the development and utilization of ASIC, at the same time pay attention to improving the anti-interference performance of intelligent controllers, and develop independent intelligent controllers which are safe, reliable and adaptable in China. This will help reduce the cost of using intelligent controllers in China and improve economic benefits. In addition, the development of computer technology and data information processing technology must be improved and perfected according to the characteristics of intelligent controller as far as possible, and the development of network control software should be strengthened to optimize interpersonal interface. In fact, in the power system, in addition to the intelligent controller of the power switch cabinet, there are many electronic components with a variety of functions. Therefore, while paying attention to the optimization and development of intelligent controller for power switch cabinet, we should also pay attention to the adaptive research of intelligent controller and other related supporting components, so as to ensure the smooth and stable operation of intelligent controller and other components, so as to improve the system, simplify the operation and improve the operation efficiency of power system. The social and economic development of our country is very rapid. The design researchers must strengthen the research on intelligent controller of power switch cabinet, promote the development of intelligent controller of power switch cabinet towards standardization of form, network and decentralization of system, and promote the economic efficiency of power system operation.
