Study on the Theoretical Calculation of Line Loss Considering Different Wiring Modes

结合不同接线模式下的中压配电网线损理论计算结果,运用等值电阻法对线路的总损耗和线损率进行计算比较,得出线损率随着接线模式的不同而相应变化。从而确定不同负荷密度下的最佳接线,为以后中压配电网规划建设制定科学合理的接入方案,保证中压配电网的灵活性、合理性,提高电网运行的经济性。

Based on the theoretical calculation results of line loss in medium voltage distribution network under different wiring modes,the total loss and line loss rate of line were calculated and compared by equivalent resistance method,and the line loss rate was correspondingly changed as the wiring mode is different.So as to determine the best connection under different load density,and make a scientific and reasonable access plan for future medium voltage distribution network planning and construction,ensure the flexibility and rationality of medium voltage distribution network,and improve the economic performance of power grid operation.
