摘要 随着电网规模的扩大,母线短路电流不断增大。目前常采用加装限流电抗器的方法来限制500 kV电网的三相短路电流。文中提出一种采用粒子群算法优化配置限流电抗器的方法,在满足限制短路电流的前提下,加装电抗器的数量和总阻抗最小,同时保证系统正常运行。通过在IEEE30节点系统的测试,以及与枚举法结果的比较,验证了该方法的实用性和可靠性。采用该方法限制江苏电网短路电流,取得很好的效果,达到设计的要求。 With the continuously increasing scale of the power system,the short-circuit current of buses is consequently increasing.At present,the current-limiting inductor(series inductor) is often used to limit the three-phase fault current in 500 kV power system.The paper presents a new approach for optimal CLI location based on particle swarm optimization(PSO),to make the quantity and total impedance of CLI least and ensure power system normal operation in the premise of meeting short-circuit current limit.The practicability and reliability of the approach is verified by comparison with enumeration results of an IEEE 30-bus system.The approach has been applied to the Jiangsu Power Grid and met the design requirements.
