The electrical motor is the most common type of power that is used to start the gas turbines in a combined cycle power plant. There are some applications where the start-up power is provided by steam turbines and diesel engines. Diesel engines are used in plants where black starts are needed. A black start is needed where there is no electrical power available for start-up power. The new large gas turbines use the generator as a motor for start-up requirements. The generator acts as a motor to bring the turbine to a point where the turbine is fired. Once the...
