Dear sir,
I am working in CPP with 750 MW power generation capacity. There are 6 gas turbine generators. Generators have both overvoltage and overexcitation protection. If overexcitation occurs, then overvoltage protection can also sense this fault. So my question is why are both protections used? Is the function of both protections the same or different? Are both really needed?
