Wind Farm Relay Protection Logic

The overcurrent and earth fault protection relays (ANSI 50/51) will be implemented to safeguard against excessive currents due to short circuits or overloads. Working group C25 was given the assignment to write a report to provide guidance on present relay protection and coordination practices at Wind-powered Electricity generating Plants (WEP). Collector. Need for a System Wide Protective Application apart from Control What does the W650 do ? Oscillography – Up to 20 oscillography files programmable from 4-64 samples/cycle, 1MB of data, analog and digital signals. Retrievable via front panel or system communications. The report includes protection of generator step up transformers, collector system feeders.
