静止无功补偿器在交直流系统中最优安装位置的选择

摘要

采用局部参数化的连续潮流法和分岔理论，研究了静止无功补偿器(SVC)在交直流互联系统中的最优安装位置。以WSCC9节点测试系统为例，通过追踪系统的平衡解流行曲线和搜索系统稳定极限的分岔点，得出系统中对无功不足比较敏感的母线，并通过在某一母线节点处添加SVC提高整个交直流系统电压稳定性，实现了在最经济情况下使系统的无功功率得到补偿的目的。%Adopting local parameterized continuous trend method and bifurcation theory, this paper studied the optimal installation location of static var compensator (SVC) in AC/DC interconnected system. Taking the WSCC9 node test system for example, by tracking the epidem-ic curve of the system equilibrium solution and searching the bifurcation point of system stability limit, the more sensitive bus to insufifcient reactive power compensation was obtained in the system. And the voltage stability of the whole AC/DC system at a bus node was improved to realize the compensation of the system reactive power in the most economic situation.
