Analysis on Impacts of Asynchronous Wind Farm on Fault Current Characteristics and Protective Relaying of Distribution Network
摘要
Abstract
The characteristics of short-circuit current offered by asynchronous wind farm connected with distribution network during the faults occurred in the distribution network are researched. The relational expression of fault current in the distribution network containing wind farm is derived theoretically, and combining with the characteristics of short-circuit current offered by the wind farm the features of the fault current in distribution network are analyzed. A simulation model of typical distribution network containing wind farm is built on the platform of PSCAD/EMTDC, and based on analysis on calculation formula of fault current the impacts of the capacity of wind farm, its network-connected position and fault point on fault current in distribution network and protective relaying are researched by the built model. Research results show that the action performances of protective relayings for distribution network are impacted by the connection of wind farm with distribution network; impacts of wind power capacity, its network-connected position and different fault points on protective relaying differ from one another.关键词
