超高压磁控电抗器直流偏磁分析及 对横差保护的影响

Carbon Neutralization and New Power Systems, 2023
摘要:超高压磁控电抗器广泛应用在新能源送出站中,其特殊的运行特点可以为电力系统提供动态无功补偿,同时无功大小可以连续调节,解决了常规固定电抗无法适用新能源送出无功需求波动的难题。本文对超高压交流输电系统中磁控电抗器结构及工作原理进行了简单介绍,针对不同直流偏磁条件下磁控电抗器中铁芯磁饱和程度和控制电流的关系做出了分析,并对磁控电抗器匝间横差保护在不同工况下的可靠性进行了研究并提出了可行的方案,为超高压磁控电抗器保护的设计和运维提供了一定的参考。
