Abstract
The object of the invention is to provide an electric power plant and a control apparatus therefor which can obtain an emergency power supply reliably through use of the turbine starter. Another generator different from the main generator coupled to the rotor shaft of the turbine is provided to the input side of the starter via a motor, and a control apparatus is provided for electrically connecting the starter and the generators responsive to a bus voltage from the in-house power supply unit which supplies electricity to a plurality of auxiliary equipment operating in the electric power plant. Thereby, an emergency power supply can be obtained reliably by the simple configuration of the invention without installing emergency power generation facilities such as a diesel engine, gas turbine or the like. In addition, an LCI device which has been utilized only at the time of turbine start up can be utilized advantageously also at the time of emergency when the in-house power supply is lost.
