中文摘要:

本文通过对微电网及其结构的介绍,根据微电网短路容量小的特点,提出一种快速动作的保护方案,在PSCAD/EMTDC软件中搭建微电网模型,并配置电流保护和无通道保护相结合的保护方案,通过仿真分析验证了该保护配置的有效性。

英文摘要:

Based on the micro power grid and its structure is introduced, according to the characteristics of micro grid short-circuit capacity is small, a protection scheme for the fast action, build the micro grid model in PSCAD/EMTDC software, protection scheme and configuration of current protection and non-communication protection combined, through the simulation analysis to verify the validity of the protection configuration.
