摘　　要：以鞍山10kV配电网为背景,研究了实用的三相潮流在线计算方法。解决了节点导纳矩阵奇异、内存占用量大、给定已知条件数目少于未知条件、应用平衡节点实测线电压计算以及节点零序注入电流影响收敛的问题。鞍山配电网在线潮流计算程序长期运行结果表明,该方法收敛可靠,计算速度快,适合配电网在线计算。A three-phase on-line power flow algorithm is studied based on the Anshan 10 kV distribution system,which has a good solution to such problems as admittance matrix’s singularness,large memory demand,the number of known conditions being less than that of the unknown,convergence influenced by zero-sequence current injection.The long-term performance of the on-line power flow program for Anshan distribution system shows that this method has the advantage of reliable convergence and high speed calculation and is suitable for on-line power flow calculation for distribution system.
