抽能电抗器运行工况下的仿真设计和优化
|
摘要
从分析抽能电抗器高压绕组和抽能绕组特殊的电磁耦合关系和结构出发,应用硅钢叠片各向异性等建模方法,仿真分析了抽能电抗器空载、额定运行以及短路故障下的性能指标,并提出了改进措施。
Based on the analysis of the special electromagnetic coupling relation and structure of high-voltage winding and energy-extraction winding in energy-extraction reactor, the performance indexes of the energy-extraction reactor under no-load, rated operation and short-circuit fault are simulated and analyzed by using the modeling method of silicon steel sheet anisotropy. The improvement measures are put forward.
