| 摘 要： | 为研究电气化铁路牵引负荷产生的负序电流对公用电网的影响,必须建立其负序电流源仿真模型.以牵引变电站高压侧母线正序电压和牵引负荷正序电流为激励,牵引负荷注入公用电网的负序电流为响应,运用支持向量机原理建立牵引负荷的负序源模型.牵引负荷运行工况随机可变环境下的仿真数据样本的总体测辨建模结果表明,模型具有良好的描述能力和泛化能力.比较WSCC-9节点系统的负序潮流计算和Matalab仿真平台的运行工况模拟结果,验证了模型的正确性和实用性.

| Abstract: | To study the negative sequence current impact of the electrified railway traction loads on the public power grid,their negative sequence current source simulation model should be set up.The positive sequence voltage of the high-voltage side of the traction substation and positive sequence current of traction load are used as excitation,negative sequence current of traction load which flows into the power grid is used as the response,and the support vector machine principle is applied to set up the negative ... |
