微电网电流保护问题及其改进策略研究
Micro current protection of electric network problems and improvement strategies
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.
