摘要/Abstract

摘要： 磁阀式可控电抗器(MCR)是电力系统中的无功补偿装置，其容量调节通过改变磁阀的铁心饱和度实现。为了对MCR的铁心饱和度进行实时、准确的分析，从而优化MCR的输出控制，保障铁心磁阀安全可靠工作，基于Jiles-Atherton (J-A)逆模型对MCR进行数学建模，并通过电磁计算程序，对比分析不同状态变量对MCR输出特性的影响。结果表明，励磁支路的直流激磁电流与饱和度具有较好的线性关系，可以作为铁心饱和度的分析及观测指标。研究及结论有助于实现MCR铁心饱和程度及励磁支路状态的在线监测，优化调控MCR输出无功功率。

Abstract: Magnetic-valve controlled reactor (MCR) is a reactive compensation device in power system, and its capacity is regulated through changing the saturation of iron core. In order to accurately analyze the core saturation of MCR in real time for optimizing the output control of MCR and guaranteeing the safe and reliable operation of magnetic valves, a mathematical model of MCR is established based on Jiles-Atherton (J-A) inverse model and the effects of different state variables on the output characteristics of MCR are compared and analyzed with the electromagnetic computing program. The results show that the DC excitation current of the excitation branch presents linear relationship with the saturation degree. Therefore the DC excitation current can be used as an index for core saturation observation and analysis. The reached conclusions are helpful for realizing the on-line monitoring of the MCR core saturation and the operating state of excitation branch, and for optimizing the control of the output reactive power of MCR.
