摘　　要：为便于装置型式选择,回顾常见特殊负荷引起的主要电能质量问题及动态无功补偿装置应用情况,分析动态无功补偿装置(SVC、SVG)的基本原理、组成型式,总结其特点与应用场合并详细介绍了PSD-BPA仿真软件中关于SVC、SVG的仿真控制模型。通过对薄弱电网某工程案例的仿真分析,结果表明,电压稳定性主要与动态无功补偿装置容量有关,在容量确定的情况下,可以通过优化控制参数来减小电压波动。In order to facilitate the selection of devices,the main power quality problems caused by common special loads and the application of dynamic reactive power compensation devices are reviewed.The basic principles and composition types of dynamic reactive power compensation devices(SVC,SVG)are analyzed.Their characteristics and applications are summarized.The simulation control model of SVC and SVG in PSD-BPA simulation software is introduced in detail.Through the simulation analysis of a project case of weak grid,the results verify that the voltage stability is mainly related to the capacity of dynamic reactive power compensation device,and in the case of certain capacity,voltage fluctuation can be reduced by optimizing control parameters.
