Distributed power supply for relay protection

Home / Distributed power supply for relay protection

This paper proposes the configuration principles and requirements for distributed protection relay protection and safety automatic devices with distributed power supply, which can provide reference for the safe and reliable operation of distribution networks with. The issues covered include protective device coordination problems due to infeed and bi-directional current flow; effects on synchronizing and autoreclosing; the potential for. After the distributed power supply is connected to the distribution network, it has a great impact on the original relay protection and brings a new challenge to the existing protection configuration scheme. By constructing a simulation model of a distributed power generation system, we compared and analyzed the performance of traditional fixed threshold.
