  • The output of small hydro power plant was generated less than rated output under high temperature. We Installed the artificial ventilation that blow cold wind from water supply pipe tunnel to small hydro power plant. The temperature of small hydro power has been decreased. The output of small hydro power plant has been increased from 405kW to 445kW.

  • Microcomputer-based PID governor which can be provided either stability or rapid response for small hydro power plant at low cost is developed and adapted to the 5 KW model hydro power for the performance test. The effects of PID gains on stability boundaries of the hydraulic turbine generating system is investigated. For the optimum selection of the PID gains, general equations are derived on the base of the experiments. This control system has a good performance at the model of hydro power plant. For the prediction of the control system, a mathematical model was developed and the results of the simulation using this model was matched with the experimental results.

  • Automatic control equipment in hydro power plant, such as turbine governor or automatic voltage regulator have to act promptly against for variation of power system, so it is necessary to check and test continuously. During last five years, the performance test of automatic control equipment was performed about 20 units of hydro turbine generator. In this process, because it has complex connection and before calibration, signal conditioner was developed as an auxiliary equipment for performance test. It includes function of signal amplifier, transducer, and meters. As a result of use this equipment for electric governor test at soyang-gang hydro power plant, it was possible to find output data equal to old one.

  • Renewable and unutilized energy (biogas power generation, wind power, solar, small hydro-power, sewage heat source, etc.) seems to be suitable to install for the sewage treatment facilities. There are 357 sewage treatment plants in 2007. 17 plants among these have been operating for self-supporting energy by using solar power, small hydro-power and biogas in 2008. Newly built sewage treatment plant of 96,000 $m^3$/day for a newtown is expected to get up to energy consumption of 10 GWh/yr. If solar energy, small hydro-power and biogas-equipments were applied to the new treatment plant, self-supporting energy of the new sewage treatment plant will get up to 56.1%. As a results, about 2,379ton $CO_2$/yr $CO_2$ emission reduction can be expected by using renewable energy. These efforts for self-supporting energy will lead sewage treatment plant to new energy recycle center.

  • Condition-based maintenance (CBM) has been used as a useful concept for optimizing maintenance plan and decreasing maintenance cost in several kinds of plant sites. This study introduced an example that developed an integrated management system for maintenance parameters and hydraulic turbine of hydro-power plant in order to improve its maintenance system as applying CBM techinique. The integrated management system consists of three parts. One is a hardware part including PDA inspection system and several kind of precision measuring instruments. Another is a vibration monitoring system on hydraulic turbine. The other is a software part that takes charge of making hierarchy tree of maintenance parameters and their inspection route, managing accumulated database, assessing health condition of components, and supporting interface with other enterprise management system. The system has been installed at Chuncheon Hydro-power plant for test and demonstration. It is expected that the system can contribute database construction for diagnostics and prognostics on facility health condition and systematic accumulation of know-how on operation and maintenance of plant.

  • Now Korea depends upon the imported resources for about 97% of total using energy. So from October, 2001 Korean government has supported renewable energy business owners by providing them with Electric Power Industry Basis Fund. Only plant-use electricity of the small hydro power plant is exactly managed, but other renewable energy plants is unprepared or not yet managed. Therefore, in this paper, we'll analyze the plant-use electricity management of the small hydro power and propose improvement plans for plant-use electricity of the photovoltaic power plant.

  • 본 연구는 해양소수력발전소에서의 튜블러 수차의 성능평가를 위한 현장시험 및 그 결과에 대한 내용을 포함하고 있다. 현장시험용 수차의 발전기 최소출력은 측정된 유효낙차, 출력 그리고 효율을 이용하여 검토되었다. 정격 및 최대 출력시험은 수차 설치현장의 조수간만의 차에 의한 영으로 인하여 동일한 실험조건을 확보할 수 없었기 때문에 모델시험에 의한 성능 데이터를 이용하여 환산된 값을 사용하였다. 현장시험에 의한 수차의 성능은 최소출력, 정격출력, 최대출력 운전점에서 보증출력 및 보증효율을 만족시키는 결과를 나타냄을 확인하였다.
