Analysis of the Influence of Distributed New Energy Access on Relay Protection

Abstract

Access to new energy large scale has changed our traditional characteristics produced during operation of electric power system, relay protection of our traditional and automatic safety devices bring higher requirements and challenges [1-2]. This paper introduces the situation of new energy power generation connected to a power grid, analyzes the operation risk of new energy access on distance protection and safety device and puts forward some suggestions and measures to resist the risk of power grid relay protection and self-installation. Research and analysis on relay protection and safety device for distributed new energy access to a regional power grid.
