摘要

在我国普遍采用高压电抗器作为工频过电压的限制措施和可控串补（TCSC）日益广泛使用的背景下

为了详细考虑串补输电系统规划中高压电抗器限制工频过电压和TCSC提高暂态稳定性的作用

提出了一种"仿线性规划"的优化方法。采用该方法

从高压电抗器限制工频过电压和TCSC提高暂态稳定性的原理出发

以保证安全稳定性条件下的经济性最优为优化目标

根据具有TCSC输电系统各参数间的相互关系

可以得出串补输电系统的优化规划方案。实际输电背景的算例分析结果说明

该提出的方法能够从原理上明确地分析得到经济性最优条件下的配置方案

实现串补输电系统的优化规划。

Abstract

Because HV shunt reactors are generally applied to limit power-frequency overvoltage in China and more and more TCSC are adopted in power transmission system

their functions in limiting power-frequency overvoltage and improving transient stability should be specially considered in the planning of series-compensated power transmission system. Consequently

we proposed a method of "pseudo-linear programming" to realize optimal scheme for series-compensated power transmission system. Using this method

according to the basic principle considering power-frequency overvoltage and transient stability of series-compensated power transmission system and the optimal economical object

we could get proper parameters of series capacitors and shunt reactors to realize optimal scheme. The proposed method has been applied to an existing power transmission background

showing its applicability.
