摘要
三相四线制供电系统线损分算求和法从完善现场运行计算条件,建立a相、b相、c相、零线的计算图,按相、零线计算出均方根电流;按用户用电量计算分配系数及各支线、线段的均方根电流;根据导线电阻参数,计算各线段、各支线的电阻,从而计算出各线段、各支线电能损失,进而相加得出计算相或其零线的电能损失,最后三相电能损失加上零线电能损失便得到该台区理论线损值。
Line loss calculation of three phase four wires power supply system gives calculation graph about phase Aphase Bphase C and null linecalculates RMS current according to phase and null line.Calculate distribution coefficient and every line segment RMS current according to user's electric energy used.Calculate resistance of every segment and every branchthus add to get energy loss of phase and Its null line.At last theory line lossValue of the station can be gotton through adding three phase energy loss with null line energy loss.
