Abstract

The invention discloses a power system simulation fault generation method, which comprises the steps of reading a power flow data file of a power system, and obtaining a basic topological structure ofthe power system according to the power flow data file; identifying a fault topology node of the power system according to the power flow data file and the basic topology structure of the power system, and acquiring topology information of the fault topology node; according to the topology information of the fault topology node, identifying a fault setting element of the power system and the topology information of the fault setting element, wherein the fault setting element comprises a line, a three-winding transformer, a power plant and a direct current system; and according to the topological information of the fault setting element, setting a fault type and generating a required simulation fault. The topological structure of the power system can be accurately analyzed, a fault demandsuitable for power system simulation can be quickly and completely generated, and safe and stable operation of a power grid is ensured. The invention further discloses a power system simulation faultgeneration device.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a method and device for generating simulated faults in electric power systems. Background technique [0002] The safe and stable operation of the power grid is of great significance to the national economy. With the continuous development of the national economy, the power grid continues to grow and develop. The operating environment of the power system is also more complex, and the requirements for the safe and stable operation of the power grid are getting higher and higher. [0003] To ensure the safe and stable operation of the power grid, a lot of system research work is required to study effective measures to maintain the stable operation of the system under various operating conditions. Therefore, a large number of fault simulation calculations must be carried out, which requires a complete and reasonable simulation fault set . In addition to manually filli...
