This paper presents a study of the performance of distance protection relays when series compensation (SC) is inserted on double circuit transmission line high voltage (HV) 400 kV in Algeria (Group Sonelgaz). The relays setting for distance protection is considered as a great challenge to power system protection engineers. Special considerations on the transmission line impedance measurement ar...

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 beco...

For the distance protection applied in converter-interfaced renewable energy systems, various AC fault ride-through strategies of sources will cause a large phase difference between operating current relay and current, resulting mal-operation relay. To overcome this issue, paper proposes an active control for systems to enhance reliability This scheme firstly calculates by only using local meas...
