FACTS 装置最佳设置点的选择指标

AN INDEX FOR OPTIMAL LOCATION OF FACTS DEVICE

在实际安装ＦＡＣＴＳ装置时，需要首先选择ＦＡＣＴＳ装置的最佳安装地点。文中采用模态分析方法，通过分析ＦＡＣＴＳ装置对电力系统稳态稳定性的影响，提出了用于提高系统稳态稳定性的ＦＡＣＴＳ装置最佳设置点的选择指标，其特点是不必对整个系统进行仿真。通过对实际系统的特征值计算和仿真，验证了所提出的选择指标的有效性和实用性。

This paper proposes an index for determining the optimal location of FACTS. device.By means of modal analysis,the index is determined by the variation of eigenvalues of the space equation for steady state.Through the use of the index,the system doesn't need to be simulated thoroughly.Applying this method to a 3-machine9-bus system with a TCSC shows that the method is practical.
