10kV配电网单相接地故障模拟仿真建模技术研究
Research on Simulation and Modeling Technology for Single-Phase Grounding Fault in 10 kV Distribution Network
摘要
Abstract
In order to realize a comprehensive,fast,and economical assessment of the grounding faults disposal algorithm in the power system digital simulation platform,the author proposes a simulation modeling method for single-phase grounding faults in a 10 kV distribution network,which can realize the system capacitance current design and verification,neutral grounding switching control,Z-shaped grounding transformer modeling and parameter verification.Based on the modeling method,the modeling is completed in Real Time Digital Simulation System(RTDS)and connected to the small current grounding selection device for test verification.The results show that the key parameters of the simulation model of the distribution network meet the design expectations,and the small-current grounding routing device is correctly routed.关键词
