一种基于方向元件的微网保护控制方案
A novel protection control method for the micro-grid based on directional component
More attention is paid to the micro-grid with the development of renewable sources. A negative sequence directional component is proposed based on the analysis of micro-grid construction in island operation. This novel protection scheme only compares the phase difference between negative sequence voltage and current in relay location, and it has a good adaptation of fault resistance. The simulation results based on PSCAD/EMTDC prove the conclusions to be correct.
