摘要（英）：

The invention discloses a power system fault monitoring method. The power system fault monitoring method comprises the steps of generating a power flow network structure through an electric system, calculating the operating parameters of the electric system, simulating the electric system according to the calculated operating parameters, and monitoring the fault of a microcomputer protection device in the electric system according to the simulation result. In addition, the invention discloses a power system fault monitoring system. According to the power system fault monitoring method, the real-time power flow network structure is generated through modeling of the electric system, simulating monitoring physical quantity of the actual electric system is obtained through simulation model calculation, electric monitoring quantity is directly input into a comprehensive protection device to simulate the on-site running condition of the electric system, and therefore on-line monitoring and examining of the power system fault can be achieved efficiently and accurately.
