【摘要】 输电系统开放后,潮流追踪的实用化研究是十分必要的。对潮流追踪的实用化进行了深入的分析,对实际电网潮流追踪中的追踪顺序采用二次排序的方法,保证了追踪顺序的快速性和正确性,对线路两端对地电容充电功率采取在线路两端加入无功功率电源的方法,在处理变压器支路负阻抗时采取将此负阻抗支路进行等效变换的方法。以某省电网系统(155个节点)作为算例进行计算,计算精度完全满足工程要求,验证了所提出方法的正确性与可行性。更多还原

【Abstract】 With transmission open access,the practicability of power flow tracing will be essen-tial.Based on its thorough analysis,a fast and accurate dual sequence method is applied to the sequence of power flow tracing.The reactive power source is added at both sides of transmission line to solve the problem of capacitor charging power.Equivalent change method is introduced to solve the issue of negative sequence reactance of transformer.Taking a transmission system(155nodes)as an example,the calculation precision completely meets the project requirements,which shows the proposed method is effective and practical.更多还原
