The invention relates to the technical field of electric power and discloses a generator exciter model checking system, which comprises a power grid data input subsystem, a power grid data processingand a checking data generation subsystem, an execution calculation subsystem, a checking result processing and a quality parameter obtaining subsystem. One end of the power grid data input subsystem is electrically connected with one end of the power grid data processing and verification data generation subsystem, the other end of the power grid data processing and verification data generation subsystem is electrically connected with one end of the execution calculation subsystem, and the other end of the execution calculation subsystem is electrically connected with one end of the verification result processing and quality parameter acquisition subsystem. The single-machine infinite-bus test system constructed based on the electric grid data processing and verification data generation subsystem of the invention checks the exciter model of the generator and greatly reduces manual operation, and the use method is simple, at the same time, the standardization of the verification result statistics can be realized, and the accuracy of the verification result can be ensured.
Description
technical field [0001] The invention relates to the field of electric power technology, in particular to a generator exciter model checking system. Background technique [0002] The excitation system of synchronous generator plays a very important role in the voltage control and stable operation of the power system. The closeness between the simulation model response of the excitation system and the actual system response is directly related to the correctness of the conclusions of the power system stability research. [0003] Excitation system model parameter checking is to simulate and calculate the established generator excitation system model in a single-machine infinite system, apply the same reference voltage step as the field test to the calculation model, check the calculation results of the simulation model, and count the simulation model The five quality parameters of the result curve, including rise time Tup, peak time TP, overshoot MP, adjustment time Ts, and num...
