摘要

针对传统500 kV变电站低端无功补偿装置容量仅靠经验判断没有系统的计算方法问题

本文分析比较了确定500 kV变电站低端补偿容量的综合配置方法。在分析了江苏500 kV电网的无功流动情况以及现有无功补偿配置概况的基础上

分别从无功就地补偿以及分层分区平衡的角度、500 kV变电站加装无功补偿装置的原因、配合500 kV变电站母线电压运行在合理范围内的极限补偿容量3个不同角度提出了500 kV变电站的无功补偿配置实用化方法

通过在电力系统分析综合程序（PSASP）中搭建实际电网简化仿真模型进行仿真计算等方法

结合实际案例对3种计算方法进行分析比较

为变电站规划设计提供参考。

Abstract

As for the reactive power compensation device capacity judgment at the low end of traditional 500 kV substation is relied only experience and without systematic calculation method

in this paper

the comprehensive allocation for the low end compensation capacity of 500 kV substation is determined by way of analysis and comparison. On the basis of the reactive power flow situation and existing allocation condition of the reactive power compensation in 500 kV grid in Jiangsu Province

the practical method of the reactive power compensation allocation for 500 kV substation is proposed from such three aspects as reactive power local compensation and hierarchical partitioning equilibrium

the reason of installing reactive power compensation device for 500 kV substation and the limit compensation capacity for the busbar voltage of 500 kV substation operating within reasonable range. The simulation calculation is made with the simplified simulation model which is set up in power system analysis software package（PSASP）. The three methods are analyzed and compared with combination of actual case so to provide reference for the plan and design of substation
