Analysis of Influence of Distributed Photovoltaic on 10kV Line Relay Protection

Photovoltaic power generation is the most significant way to utilize solar energy in world today. Facing severe fossil crisis and environmental facing today, photovoltaic has obvious advantages from perspective of resource sustainability friendliness. The access distributed sources will change flow distribution network. If grid-connected load light, capacity large. After connected, network become a multi-source network, output be During this period, line prone reverse current flow, which increases voltage affects quality Thence, it essential consider adopting strategies control ensure safe steady operation
