Introduction

Cenjing Xu is a notable inventor based in Zhejiang, China. He has made significant contributions to the field of photovoltaic technology, particularly in ground fault protection methods. His innovative approach addresses critical safety concerns in photovoltaic station output transmission lines.

Latest Patents

Cenjing Xu holds a patent for a "Ground fault protection method and apparatus for photovoltaic station output transmission line." This invention provides a method for controlling a circuit breaker on the photovoltaic side through a control element. It determines whether the measured zero sequence impedance on the photovoltaic side has a significant variation before and after the action of power grid side distance protection. If the variation is less than a set value, a tripping signal is sent to the circuit breaker to isolate the fault. Conversely, if the variation exceeds the set value, the photovoltaic side distance protection is not activated. This innovative method enhances the safety and reliability of photovoltaic systems.
