摘要
以同一系统中静止同步串联补偿器(static synchronous series compensator,SSSC)和静止无功补偿器(static var compensator,SVC)的共同作用为研究对象,建立了2者的数学参数模型,推导出控制器之间相互作用的量化关系式。通过控制参数分析和仿真分析得出结论:灵活交流输电(FACTS)装置的控制方式和电气耦合程度对SSSC和SVC的相互作用有很大影响。最后基于直接反馈线性化(DFL)方法设计了SSSC和SVC协调控制器,仿真结果验证了该协调控制策略的有效性。
Taking the interaction between static synchronous series compensator (SSSC) and static var compensator (SVC) in the same power system as subject investigated, the mathematical parameter models for them are established, and quantized relational expressions for the interaction between the two controllers are deduced. By means of the analysis on controlling parameters and simulation, such a conclusion is obtained that the control mode of FACTS devices and their electric coupling degree greatly impact the interaction between SSSC and SVC. Based on direct feedback linearization (DFL) method, a coordination controller for SSSC and SVC is designed, and simulation results validate the effectiveness of this coordination control strategy.
