The Study on the Design and Protection Configuration of Building PEDF System

Aiming at the application of PEDF technology in buildings, the design points of building PEDF system, including topology structure, voltage level and energy storage configuration are analyzed, and the corresponding protection configuration is studied. The strategy of fault classification protection based on microcomputer protection and the method of residual current protection coordination based on flexible grounding are proposed. The effectiveness of the design method is proved by practical system test.
