摘要/Abstract

摘要： 建立详细的三相变压器模型对配电网分析至关重要。在所建立的变压器三相模型基础上,对比分析了相间磁耦合和励磁支路对模型的影响,讨论了零序参数和励磁支路参数的计算方法,并采用4节点配电网测试系统,详细分析了相间磁耦合、励磁支路对配电网三相潮流计算的影响。算例分析表明,在变压器模型中是否考虑相间磁耦合对潮流计算结果的影响较大,而且励磁支路产生的损耗不应忽略。

Abstract: The establishment of the detailed three-phase transformer model is critical to distribution network analysis. Based on the established model, the interphase magnetic coupling and magnetizing branches influence on the transformer model are analyzed, and estimations of zero-sequence parameters and excitation branch parameters are discussed. Then, based on the IEEE 4-bus distribution test system, the detailed analysis of the power flow calculation is given, which includes the influences of the inter-phase magnetic coupling and magnetizing branches. The results of the test cases show that the interphase magnetic coupling has great impact on the results of three-phase power flow and the excitation loss should not be neglected.

Key words: distribution system, transformer models, magnetizing branches, power flow calculation
