Although the report addresses coordination with wind turbine generator protective devices and static VAR sources, protection of the wind turbine generators and static VAR sources themselves is not included. Large WEPs are becoming more prevalent as generation sources on the power system.
Generators are the most expensive pieces of equipment on power systems. The following devices are used for AC and DC generators protection against the faults occurs in it. Reliable protective relaying schemes are therefore required to detect and clear generator faults quickly to minimize damage and reduce repair time to a minimum.
Various protections of this class are: 220 KV (HV side of Generator Transformer) busbar protections. Generator Transformer HV side breaker pole discrepancy. Impedance/Over current back-up protection, etc 2nd harmonics restrained. Figure 1 – Generator protection single line diagram 1. Generator differential protection (87 G)
The wind turbine protection scheme may include voltage and frequency relaying to protect the generator. For example, some wind turbines may trip for frequencies at or below 95 percent of nominal, or above 103 percent of nominal, with an appropriate time delay.
Wind turbines with doubly-fed generators The doubly-fed concept gets its name from the fact that the generator feeds power from both the generator''s stator and rotor: two-thirds of nominal
