摘要

Parameter identification method was discussed in this paper. Through the experiment analysis of the measurement realpower and voltage signals and by aid of Matlab Optimization Toolbox, the method and steps of parameter identification ofdynamic load modeling was given. Experiment results showed that the model obtained by parameter identification could reflect thevarious rules of real power signals measured in power system. It is important for the research on the feature of dynamic loadmodeling.%针对动态负荷模型的参数辨识问题进行研究.通过对实测电网有功功率和电压信号的实验分析,借助MATLAB系统优化工具箱,给出了动态负荷模型参数辨识的具体方法和步骤.结果表明:利用参数辨识方法得到的负荷模型能够较好地体现电网实测有功功率的变化规律,对于深入研究电网动态负荷模型的特性有重要意义.
