摘　　要：为分析新型电力系统的长时间尺度特性,需开展多时间断面下的潮流计算。提出基于全纯嵌入的多时间断面潮流快速计算方法,在较小的误差下实现配电网多时间断面电压幅值和相角的快速计算。对全纯嵌入法中的电压幂级数系数开展数值分析,推导出电压幂级数系数的线性计算方法。在此基础上,提出2种多时间断面潮流快速计算方式。配电网测试系统的测试结果验证了所提方法的有效性。In order to analyze the long-term characteristics of new power system,it is needed to carry out power flow calculation under multi-time section.A fast calculation method of multi-time section power flow based on holomorphic embedding is proposed,which realizes fast calculation of voltage amplitude and phase angle of multi-time section for distribution network with small errors.The numerical analysis of voltage power series coefficient in the holomorphic embedding method is carried out,and the linear calculation method of voltage power series coefficient is derived.On this basis,two fast power flow calculation modes of multi-time section are proposed.The test results of distribution network test system verify the effectiveness of the proposed method.
