摘　　要：考虑到电力系统实际应用中很难获得准确的网络拓扑和参数 ,使得 FACTS控制器的参数化模型的建立与验证极为困难 ,提出采用采样调节器设计技术进行晶闸管控制串联补偿器( TCSC)与静止无功补偿器 ( SVC)的控制 ,以提高系统的暂态稳定水平。所采用的采样调节器设计技术只需事先获得系统的开环阶跃响应 ,完全建立在非参数化模型之上 ,它不但能保证闭环系统的稳定性和优越的动态性能、稳态零误差 ,而且对电力系统的非线性及运行点的变化具有足够的鲁棒性。最后 ,通过 NETOMAC仿真软件在我国阳城—淮阴输电工程中进行了仿真验证 。This paper presents a sampled regulator design method (SRDM) for TCSC and SVC control for the transient stability enhancement of long-distance transmission systems, when the accurate network topology and parameters are so difficult to be obtained that the parametric models of FACT and validity can not be implemented. The SRDM can guarantee control system stability, optimality and robustness, and only require knowledge of the open-loop system step response. i.e. a nonparametric model, which is particularly attractive for applications in power systems. The effectiveness of the proposed control design scheme is validated with the Yangcheng-Huaiyin transmission project of China, where the simulations are carried out by the NETOMAC program system.
