Publication number: 20070273342Abstract: An electric power supply apparatus includes a distributed power generator such as a gas turbine generator and a power converter such as an inverter apparatus for converting electric power generated by the distributed power generator into AC electric power (alternating-current power) having a required frequency and a required voltage and supplying the AC electric power to a load. The electric power supply apparatus further includes a control unit having output voltage vs. output current characteristics for determining an output voltage corresponding to an output current of the power converter. The output voltage vs. output current characteristics has a first dropping characteristic for causing output electric power of the electric generator to be limited, between a first output current exceeding a power generation capability of the electric generator and a second output current exceeding a power converting capability of the power converter.Type: ApplicationFiled: May 24, 2007Publication date: November 29, 2007Applicants: EBARA CORPORATION, EBARA DENSAN LTD.Inventors: Tadashi Kataoka, Shigeru Sakata, Takahide Ozawa, Isao Tsukagoshi, Zheng Dai
