摘要
互感输电线路耦合分布参数的求解是线路参数实测中的很重要的一部分,目前的计算方法仍存在一些问题。考虑同塔平行双回线模型(两端共母线的双回线)存在特殊性,对此种情况下的耦合参数具体计算方法进行了研究。另外,录波器两端采样会存在不同步问题,因此提出了在双端录波器采样不同步的条件计算双回线耦合参数的方法。通过仿真计算,验证了方法的有效性。
Accurate line parameters are the basis of the calculation and analysis for power system. There are still some problems to be solved. With particular characteristics, the parameter calculation method of coupled double lines with same transmission tower is proposed. Considering the recorder used in practice cannot guarantee the synchronization of the two- terminals of the transmission line, a method which can calculate parameters of the transmission line basing on asynchronous two-~terminal data is proposed. The method is verified by MATLAB simulation.
