摘要
针对新型电力系统中不同组成、不同复杂程度的综合负荷,亟需一种通用的模型结构来满足新型电力系统在线安全分析精度的要求。对含电动机负荷和静态负荷的综合负荷模型进行研究,分别建立新型电力系统下考虑电压相角变化和忽略电压相角变化的综合负荷广义离散等值模型,得到综合负荷广义离散等值模型的参数,并分析模型参数与电力系统各元件的内在联系以及各模型系数间的物理特性。通过CEPRI-36节点系统的仿真对比验证了所建模型的普适性和有效性。
Aiming at the composite load with different compositions and complexities in the new-type power system,a general model structure is urgently needed to meet the requirement of accuracy of online safety analysis for the new-type power system.The CLM(Composite Load Model) with motor load and static load is researched,the generalized discrete equivalent models for CLM with and without considering the variation of voltage phase angle are respectively built,the parameters of the generalized discrete equivalent models of composite load are obtained,and the inherent relations between model parameters and each component of power system and the physical characteristics among the model parameters are analyzed.The adaptability and effectiveness of the proposed model are verified by the simulation and comparison of CEPRI 36-bus system.
