| 摘 要： | 方均根电流法是广为应用的理论线损计算方法,交流超特高压线路长、电压高、分布电容电流大,传统的方均根电流法对于超特高压长线的理论线损计算精度降低。通过分析超高压长线分布电容电流及高压并联电抗器对传统方均根电流线损理论计算的影响,文章提出了一种补偿分布电容电流影响的方均根电流理论线损算法,适用于带高压并联电抗器的超特高压长线路。通过安徽电网EMS在线理论线损计算平台的实践应用,进一步证明了本实用算法的有效性。

| Abstract: | Traditional RMS current method of transmission line power loss is applied widely .However , its calculation precision of long UHV transmission line is compromised when the large distribution capaci -tance current and UHV shunt reactance are given .Based on analysis of the calculation error caused by distribution capacitance current and shunt reactance , a new type of on-line RMS current power loss calcu-lation method of shunt current compensation is presented , which has also been proved suitable for long UHV transmission lines with shunt reactance .The effectiveness of the new method has also been demon-strated via the practical calculation results based on EMS of Anhui power grid . |
