摘要
以基于储能的有功、无功皆可动态调节的静止伏安发生装置SVAG为实验平台,对孤立微网中两个不同容量SVAG并联系统带动态负荷运行的特性进行了分析。应用下垂控制策略的SVAG并联系统的控制目标是在微网中的动态负荷发生突变时实现不同容量SVAG间的负荷协调分配,以维持系统稳定运行,在PSCAD/EMTDC软件中搭建模型进行仿真分析并在SVAG物理装置上开展实验,仿真结果和实验结果验证了采用下垂控制策略的SVAG并联系统具有一定程度的抑制环流作用和良好的负荷分配特性。
The parallel operation characteristics of two dynamically loaded SVAGs （Static VA Generator） with differ- ent capacities in an isolated microgrid are analyzed on the SVAG experimental platform, which can regulate active and reactive power based on energy storage. Droop control strategy is applied to SVAG parallel system in order to reasona- bly distribute load between SVAGs with different capacities and to maintain stable operation state in case of abrupt change of dynamic load in microgrid. Simulation analysis is conducted on the model built in PSCAD/EMTDC soft- ware, and experiments are made on SVAG physical devices. The simulation and experiment results verify that parallel operation SVAG using droop control could restrain circular current and is superior in load distribution.
