负荷模型对基于能量函数的扰动源溯源的影响研究

Impact of Load Model on Disturbance Sources Locating Based on Energy Function

电力系统规划、运行、控制、设计都依赖仿真完成。仿真的准确度关系到电力系统的安全稳定运行,负荷模型对仿真结果的影响更是不容小视。针对基于能量函数的共振型低频振荡扰动源溯源方法,在仿真软件PSS_E环境下,选取了几种具有代表性的负荷模型,验证了能量函数法在不同负荷模型下的溯源效果,分析并讨论了负荷模型对基于能量函数的共振型低频振荡扰动源溯源的影响。

Simulation is the base of power system planning, operation, control and design. The accuracy rating of simulation has an important significance for security and steady operation of power system, and load model seriously impacts simulation results. In this paper, several typical load models are chosen to verify the effect of load models on the disturbance source locating of low frequency oscillation of resonance mechanism based on energy function in PSS_E, and the simulation results are analyzed and discussed.
