Test Devices for Bi-Directional Coordination of New Energy SourcesPV Systems in Secondary Feeders

摘要

PURPOSE: A bidirectional protection coordination testing device of a new energy(sunlight) power source is provided to be used for the system interconnection of various energy power sources by performing a simulation for the protection coordination, voltage variation, power quality of a energy power source based on the system interconnection guide line of the energy power source. CONSTITUTION: A simulated distribution system apparatus contracts an actual distribution system and performs simulation to test and analyze the influence of an energy power source on a system. A surveillance control part includes a function for controlling and analyzing a protection coordination testing device. A protection coordination apparatus offers a protective relay and the high accuracy measurement of electric power distribution facilities. A bidirectional protection coordination testing device consists of a simulated load device, which reduces the load of a system and performs the same function as an actual distribution system.
