| 摘 要： | 分析研究了配电网多种典型接线模式在不同负荷密度、不同变电站容量下计及可靠性收益的线路最优分段数。以配电网可靠性和经济性综合最佳为目标,考虑变电站、线路建设和运行等费用,采用"现值转年值"的方法将一次投资费用转化为年费用,确定各典型接线模式在多阶段负荷密度及普适性变电站场景下的最优分段数。最后通过仿真算例验证了本算法的合理性。

| Abstract: | The optimal sectionalizing number of transmission line with the consideration of reliability for various typical connection modes with different load density and substation capacity is studied. The optimization uses an economy and reliability combined objective function, and the construction and operation costs of substations and lines are considered. With the optimization, the optimal sectionalizing number of lines for a multi-phase load density and a universal substation scenario is obtained. The simulation results validate the proposed approach. |
