A first primary winding Nof a transformeris connected with a commercial power sourcevia a transistor Q, and a second primary winding Nof the transformeris connected with a backup batteryvia a transistor Q. An electric power on the second primary winding Nis output for a controlling apparatus. When a voltage of the commercial power sourceis larger than a predetermined value, a backup stopping circuitturns off a LEDand stops the transistor Q. The second primary winding Nis connected with input terminalsas a power source for charging a battery. While the transistor Qis stopped, an electric power for the battery is output from the second primary winding N. Since the LEDturns on at the time of electric power breakdown, the electric power for the battery is stopped.

Direct current stabilizing power source apparatus

A fault on the generator can be detected with the use of a simple arrangement. The output of the generator which has multi-phase winding and is driven by an engine is rectified and then converted by an inverter into an alternating current at the frequency of a system before interconnected to the source of the system. After the engine is started, the direct current voltage Vdc is monitored with a first fault monitor . When the direct current voltage Vdc rises up to a predetermined level, a connector relay is closed. As the output of the inverter is increased, the interconnection with the system source is enabled. After the interconnection, the direct current voltage and the output of the inverter are monitored with a second fault monitor . If the direct current voltage drops down to below the predetermined level before the output of the inverter reaches a rated level, the canceling and re-interconnection is repeated. Then, when the direct current voltage remains below the predetermined level after the re-interconnection, it is judged that the generator has a fault such as a line breakage in the windings disconnection.

Connection to grid type engine generator apparatus

A generator apparatus such as in a cogeneration system has a controlling power supply energized with its generator output with giving no adverse effect on the waveform of its output. An inverter is provided for converting an alternating current output of the engine generator into a direct current and returning back by the action of its inverter circuit to an alternating current of a predetermined frequency which is then connected to a power supply system . While the engine remains not actuated, a power received from a joint between the inverter and the power supply system is rectified by a rectifier and transferred to the controlling power supply . When the engine is started, the power at the input of the inverter circuit is transmitted to the controlling power supply . As the voltage at the input of the inverter circuit is set higher than that at the power supply system side, the energization of the controlling power supply with the power at the input of the inverter circuit can automatically be selected after the start-up of the engine.

Generator apparatus

A grid-type engine generator apparatus which can prevent reduction in the operational efficiency due to the stop motion of an engine at the cancellation of the interconnection and minimize loads exerted on the startup device for the engine. A network protector is provided for generating a fault signal when detecting a fault on the network source. Upon receiving the fault signal, an interconnection relay is opened to cancel the interconnection and simultaneously, a timer is started. The cancellation permits the engine to run with no load. When the fault signal is maintained until the setting duration of the timer is timed up, a time-out signal is released to stop the engine. On the other hand, when the fault signal is eliminated by canceling the cause of the fault before the setting duration of the timer is passed, the interconnection relay is closed to establish the interconnection again and the timer is reset.
