摘要

未来配电网的架构将具备分布式电源高密度接入、交直流混联等显著特点，配电网故障分析将面临新的挑战，高密度分布式电源及大量电力电子设备的接入，使得故障响应呈现非线性时空关联特性，交直流系统故障响应交互影响进一步加大了故障分析的难度。文中对配电网故障分析的研究现状进行了总结，进一步指出高密度分布式电源的时空关联特性解析与解耦建模、交直流配电系统的等效建模以及高效收敛的计算方法是未来配电网故障分析亟待探索的关键问题。

Abstract

The future distribution system will have the significant characteristics such as high density integration of distributed generations

interconnection of AC/DC hybrid system. Therefore

the fault analysis for distribution system will face new challenges. As the integration of high density distributed generation and power electronic equipments

the fault response presents the property of nonlinear temporal-spatial correlation

and the fault response interaction influences between AC/DC system further increase the difficulty of fault analysis. In this paper

the current research status of the distribution system fault analysis is summarized

and the key issues to be studied in the future are proposed including the analysis and decoupling modeling of distributed generations for the temporal-spatial correlation characteristics

the equivalent modeling of AC/DC hybrid distribution system

and the effective convergence algorithm.
