Protection of Wind Electric Plants

Protection of Wind Electric Plants is a report covering engineering considerations for the design of protection systems and present relay protection and coordination practices at wind electric plants. The report includes protection of generator step up transformers, collector system feeders, grounding transformers, collector substation buses, reactors, capacitors, main substation transformers, tie lines and points of interconnection and associated arc flash issues. Engineering details on possible electrical layouts, equipment ratings, system grounding, wind electric generator characteristics, transformer connections and characteristics, harmonics and sub-harmonics, voltage and frequency control requirements, and protective relay schemes are also described. The report addresses coordination with wind turbine generator protective devices and static VAR sources; however, the protection of the wind turbine generators and static VAR sources themselves is not included.
