Abstract: With the accelerated development of various fields of society, the gradual increase in power demand, coupled with the continuous upgrading of information systems, higher requirements for dispatching automation systems are also put forward. At present, China's power enterprises have built a dispatching system to meet the requirements of power grid dispatching, so as to ensure the reliable and safe operation of the power grid. Due to the unstable factors of the automation system itself, once there are problems in the operation process, it will directly lead to the effective operation of the integration of regulation and control, and even lead to the failure of dispatching, and the power grid is in a state of no monitoring. to a great extent, it increases the risk of real-time operation of the power grid. Thus, the safe and stable operation of the master station of the dispatching automation system is particularly important, and the later operation and maintenance quality has a direct imp.
