摘要
建立了STATCOM基于功率注入法的稳态模型和基于受控电流源的动态模型,并利用电力系统分析软件提供的用户自定义功能实现了这些模型,用以分析STATCOM在给定条件和控制目标下的动稳态特性.基于建立的模型,对山东电网各STATCOM装设方案进行了仿真分析.结果表明所建立的模型简单有效,STATCOM可以起到较好的动态电压支撑、强补无功和抑制电压跌落的综合效果.
Based on the injected power method and the controlled current source model, steady state and dynamic models for STATCOM are built. Both models are implemented using the user defined （UD） function of power system analysis software, and are used to study the steady state and dynamic performances of STATCOM under given conditions and control objectives. Based on these models, simulations are conducted and analyzed for each installation scheme of STATCOM in the practical Shandong power system of China. Simulation results show that the proposed models of STATCOM are simple and effective. They produce good comprehensive perfonnances on supporting dynamic voltages, compensating reactive powers and depressing voltage drops.
