摘要
TCSC的投运能够有效地提高电力系统暂态稳定性,由于TCSC价格昂贵,安装数量受到限制。文中以特征分析法、相关因子和TCSC的H_∞控制器作为工具,以系统稳定和H_∞指标作为最优配置目标来实现TCSC的最优配置。在扩展的Anderson试验电力系统模型中进行仿真,结果表明此方法可以提高多机电力系统暂态稳定性。
Thyristor Controlled Series Compensation (TCSCs) can effectively improve the transient stability in power system, but there is a limit on the number of such devices to be installed for the cost is very expensive. By Eigen-analysis, participating factor and H∞ controller as instrument, and by system Eigen value and H∞ norm as optimal index, the optimal allocation for TCSC are realized. The simulations in the extended Anderson test power system model show that they can enhance the transient stability of muhi-machine power systems.
