类噪声辨识负荷参数的实际电网校验方法

Load modeling plays an important role in power system simulation and analysis. In order to build more exact load models, attentions were paid to selection of load model structure and acquisition of load model parameters in previous researches. However, validation analysis for identified load model parameters was seldom conducted. Considering the purposes of load modeling, a validation method for the parameters identified with ambient signal with system simulation is proposed in this paper. Meanwhile, the engineering problem of converting the parameters identified with actual measurements into the parameters suitable for simulation is solved. Firstly, the load model parameters are identified with the ambient signal from phasor measurement unit (PMU). Then the identified parameters are used to replace the parameters in the simulation system after conversion. Finally, the simulation results with different load model parameters are compared to achieve validation purposes.
