Fault Detection Strategy for Two-Stage Grouping Control in Modular Series Structure Power Supply Systems
To ensure the normal operation of modular series structure power supply systems,this paper explores the fault detection strategy of two-stage grouping control in modular series structure power supply systems.This method optimizes the fault feedback signal reception mechanism of modular series structure power supplies and introduces a two-stage grouping control direct current islanding detection technology based on Maximum Power Point Tracking(MPPT).At the same time,fault criteria were designed and the detection result output process was optimized.Through practical case verification,the method proposed in this article can accurately detect faults in a short period of time,thereby significantly improving the operational stability of the power system.
