Abstract This paper introduces a main wiring form applied to the auxiliary power system of combined cycle power plant (CCPP), and analyzes the reasons why the original fast-switching system for the auxiliary power cannot achieve safe and fast switching under this wiring method. The design, protection configuration and secondary circuit are improved, and the feasibility of the improved scheme is verified through the actual test.
