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 ,证明了所设计方案的有效性
Considering that it is very difficult to obtain the accurate network topology and parameters in practical application of power system, it is extremely difficult to set up and verify the parameterized model of FACTS controller. It is proposed that the design of thyristor controlled series compensator (TCSC) Control of reactive power compensator (SVC) to improve the transient stability of the system. The sampling regulator design technique used in this paper only needs to obtain the open-loop step response of the system beforehand and is based on the non-parametric model completely. It not only guarantees the stability of the closed-loop system and the superior dynamic performance, steady state zero error, But also has enough robustness to the nonlinearity of power system and the change of operating point. Finally, the simulation results of NETOMAC simulation software in Yangcheng-Huaiyin transmission project in our country proved the effectiveness of the proposed scheme
