摘要
在配电网理论线损计算时,均方根电流法是常用的有效方法。本文通过对均方根电流法进行深入地剖析,指出了其在数值分析上的矩形积分的数学实质;同时,又提出了包括梯形积分、多项式积分、分段插值积分的的理论线损算法模型,并分别进行了误差分析;最后通过廊坊供电公司试点配电网的实测负荷数据对各种算法进行了对比分析,验证了不同算法的误差限和适用性。
The root mean square of current method (RMS) is the usual algorithm for technical loss computation of distribution network. Based on the mathematical model (rectangle integration) of the RMS method in the numerical analysis, the another algorithms including trapezium integration, polynomial integration, segment interpolation integration will be introduced, and the error analysis is given accordingly. Lastly, each algorithm will be varified by comparing and analyzing based on the measuring load dada of Langfang Power Supply Company.
