| 摘 要： | 鉴于传统合环潮流计算方法存在支路多、计算量大的缺点,提出将合环网络中多节点负荷支路简化为单节点负荷支路的思路,并建立等值模型和推导出计算公式。取一条9节点的10 kV配电网线路进行仿真实验,采用单节点模型计算得到的末端电压幅值相对误差为1.7%,相位相对误差为15.5%。仿真结果表明,该方法能满足实际工程的要求,且大大减少了合环潮流计算的工作量。

| Abstract: | In view of defects such as excessive branches and mass calculated quantities of traditional closed-loop flow calcula-tion method,this paper proposes a thinking of simplifying multiple node load branches in closed-loop network to single node load branch.Meanwhile,it discusses establishment of equivalent model and calculate formula derivation.One 9-node 1 0 kV distribution network line was taken for simulation experiment and single node model was used for calculation.By calculating, relative error of terminal voltage amplitude was worked out as 1.7% while phase relative error was 1 5.5%.The simulation result showed that this method was able to meet requirement for practical engineering and greatly reduce workload of closed-loop flow calculation. |
