Technology for Photovoltaic Module Ground Fault Location and Detection
The photoelectric conversion part of photovoltaic modules can break down or short-circuit with the external frame.Once a ground fault occurs in the photovoltaic module,it will cause the entire string to stop func-tioning properly,resulting in significant power generation losses.A non-disruptive detection method for photovol-taic module ground faults is proposed,which effectively addresses the grounding issue faced by photovoltaic mod-ules and improves the performance and efficiency of the entire photovoltaic power generation system.This method has been validated in practice and demonstrates good practicality and value.
