PURPOSE:To provide an inverter apparatus and a synchronous closing apparatus to enable, after connection of a system, power factor control and separate operation without requiring a limited current reactor by controlling power receiving coefficient with the inverter apparatus. CONSTITUTION:An induction type power generator 2 is used for self-power generation facilities such as a co-generation system, etc. Moreover, an inverter apparatus 12 for excitation to control an output voltage of the induction type power generator 2 and a synchronous closing apparatus 14 for inputting an output voltage of the induction type power generator 2 and a system voltage, detecting the in-phase point and then outputting a closing signal to a circuit breaker 6 for connecting the induction type power generator 2 to the system are further comprised. After connection of the system, the inverter apparatus 12 controls the power receiving coefficient. Therefore, since the closing becomes possible by controlling voltage and phase for the system through generation of an output voltage on the induction type power generator when it is connected to the system, an excessive current never flows at the time of closing. |
