Analysis of Relaying Protection Setting of A 10 kV Power System with Distributed Photovoltaic
Taking the 10 kV power supply system of a logistics facility containing 1.8 MWp distributed photovoltaics as an example,this paper summarizes its relay protection configuration and setting methods.This paper introduces the processing method of distributed photovoltaics in short-circuit current calculation,analyzes the impact of distributed photovoltaics on relay protection setting,and proposes configuration and setting methods for transformer protection,line protection,busbar protection,fault disconnection protection,and backup automatic switching.
