| 摘 要： | 同步相量测量单元(PMU)可以直接量测节点电压相量和与该节点相连的支路电流相量。通过在适当位置配置PMU,便可使潮流方程不需迭代直接可解,为此提出了计及PMU支路电流相量的潮流方程直接可解法,并采用粒子群优化算法解决了PMU的最优配置问题。算例结果表明本方法有效,并可以减少所需PMU的个数,因此具有实际的应用价值。

| Abstract: | Phasor Measurement Unit(PMU) can provide node voltage phasor measurements,and branch current phasor measurements connected with the node.If the PMU are equipped in the appropriate location in the net,the power flow can be directly solved without iterating.For that,this paper proposes the method of direct solution of power flow with PMU current phasor measurements,and the optimal configuration of PMU is solved by particle swarm optimization(PSO).The results demonstrate that the algorithm is effective and can decrease the amount of PMU.It is useful for practical application. |
