基于耗散功率的区域电网强迫功率振荡扰动源定位
Disturbance Source Location of Forced Power Oscillation in Regional Power Grid Based on Dissipation Power
摘要
Abstract
The continuous cyclical small signal power disturbances could excite the power system forced power oscillation,and the removal of disturbance sources can attenuate the oscillation rapidly.In order to find the specific location of the disturbance source to make the oscillation die down quickly,we analyzed the energy conversion characteristics of the forced power oscillation in a linear system during the steady-state resonance.Considering the application of practical power system and program realization of automatic positioning,we improved the energy function,and proposed a new method of disturbance source localization by using power dissipation.The proposed method is proved to be effective by case study of two-area with four-machine system,simulation model of a regional power grid,and wide area measure system（WARMS） measure data of the regional power grid.关键词
