<P>PROBLEM TO BE SOLVED: To provide generating equipment capable of causing multiple synchronous generators to start power supply to a load in a short time. <P>SOLUTION: The generating equipment includes: the synchronous generators; automatic voltage regulators that control the voltage of each generator to a desired voltage according to a voltage command signal; a prime mover starter that is connected in parallel with multiple pieces of generating equipment through generator circuit breakers and starts each prime mover when a prime mover start signal becomes true; a timer that starts counting when a prime mover start signal becomes true and outputs a true generation start signal when a preset time lapses; and a voltage command output device that outputs a voltage command signal to each automatic voltage regulator when a generation start signal becomes true. When the generator circuit breakers and a load circuit breaker are open and an external prime mover start signal is true, a prime mover is started. When a generation start signal thereafter becomes true, all the generator circuit breakers are closed to start the voltages of the generators. After start of the voltage is completed, the load circuit breaker is externally closed to start power supply to the load. Therefore, all the generators can be synchronously turned on in a short time regardless of the number of synchronous generators. <P>COPYRIGHT: (C)2007,JPO&INPIT |
