Grid security risk monitoring system

The utility model provides a grid security risk monitoring system, comprising monitoring devices respectively on monitoring points and a remote control server. The remote control server is connected with each monitoring device in a wireless manner. Each monitoring device comprises a network voltage detection circuit, a network current detection circuit, a video acquisition device, a positioning device, a meteorological data acquisition device, and a monitoring terminal RTU. The system is advantaged in that: (1) the system performs comprehensive monitoring on power grid conditions of the monitoring points to acquire various monitoring data; (2) combining a wind power generation method and a solar power supply method, energy consumption is saved under the condition that normal operation of the monitoring system is ensured, and a battery is not need to be changed frequently, thereby reducing workload of working personnel; (3) and a plurality of safety protection measures are used, for example, a lightning rod is installed and a cabinet uses an electromagnetic radiation resistant material, thereby improving operational reliability of the monitoring system.
