[0002] In recent years, with the continuous development of science and technology and industrial technology, the coverage of power consumption and power grid has become more and more extensive. Power failures are likely to cause a series of disasters such as fire accidents. The safe use of power systems has become the focus of attention. , in the daily operation of the power system, when the electrical components in the power system fail or operate abnormally, the relay protection device will control the circuit breaker to trip, thus ensuring the safe operation of other electrical components. It can be seen that, Whether the relay protection device can work normally is directly related to whether the entire power system can operate normally. Therefore, in the operation of traditional substations, maintenance personnel usually need to use some test tools to test the protection relay devices in traditional substations. The protection circuit is monitored so that it can be processed in time when the protection circuit is abnormal, so as to ensure the safe operation of the traditional substation. The relay protection equipment occasionally crashes. If the crash is not detected in time, the relay The protection equipment will malfunction or refuse to operate, which will lead to serious power accidents. Usually, the power system will send inspectors to visually observe the lighting status of the running lights on the relay protection equipment to judge its operating status, but human inspections are easy to ignore. In the case of misreading or misreading, it is often impossible to find the crash status of the relay protection equipment in time. The monitoring of the operation status of the relay protection device is a very important link in the power system protection. The current commonly used relay protection monitoring methods can be used to a certain extent However, there are still some deficiencies in pertinence and comprehensiveness. Therefore, it is necessary to design a system with reasonable design, simple structure, convenient installation and use, obvious detection effect, high work efficiency, and intelligence. It is very necessary to have an intelligent relay protection monitoring device with high degree of automation, automatic monitoring, stable work, safety and reliability, long service life, remote real-time monitoring, higher real-time performance, and a wide range of applications. The safety and stability of the device has very important significance and practical value, so that the monitoring personnel can deal with it in time according to the judgment results, thus ensuring the safe operation of the intelligent substation equipment
