  • This paper presents the methodology to analyze flow duration characteristics and performance prediction for small hydro power(SHP) plants and its application. The flow duration curvecan be decided by using monthly rainfall data at the most of the SHP sites with no useful hydrological data. It was proved that the monthly rainfall data can be characterized by using the cumulative density function of Weibull distribution and Thiessen method were adopted to decide flow duration curve at SHP plants. And, the performance prediction has been studied and development. One SHP plant was selected and performance characteristics was analyzed by using the developed technique. Primary design specfications such as design flowrate, plant capacity, operational rate and annual electricity production for the SHP plant were estimated. It was found that the methodology developed in this study can be a useful tool to predict the performance of SHP plants and candidate sites in Korea.

  • A methodology to evaluate the performance analysis for small hydropower at existing water treatment facilities has been studied. It consists of two main parts; flow duration function which can describe existing water treatment facilities and performance analysis to estimate the output characteristics of small hydro power plants. The output performance characteristics for Mi-ho reservoir, Sum-kang low dam, Sun-cheon sewage treatment plant and Nam-dong purification plant were analyzed, using developed model. According to the simulation results, the predicted data show that the data were in good agreement with measured results. Also, it was found that the developed model in this study can be used to analyze the output characteristics for small hydro power at existing water treatment facilities.

  • The effects of design parameters for small scale hydro power(SSHP) plants due to climate change have been studied. The model to predict hydrologic performance for SSHP plants is used in this study. The results from analysis far rainfall conditions based on KIER model show that the capacity and load factor of SSHP site had large difference between the period. Especially, the hydrologic performance of SSHP site due to rainfall condition of recent period varied in design flowrate sensitively. However climate change gave small effect in load factor of existing SSHP plant. And also, the methodology represented in this study can be used to decide the primary design specifications of SSHP sites.

  • The model to predict flow duration characteristics and performance for small scale hydro power(SSHP) plants is studied to analyze the effects of rainfall condition. One existing SSHP plant was selected and performance characteristics was analyzed by using the developed model. The predicted results from the model developed show that the data were in good agreement with operational results of existing SSHP plant. The results show that both the scale parameter and the shape parameter have large effects on the performance of SSHP sites. And also it was found that the model developed in this study can be a useful tool to predict the performance of SSHP sites.

  • 삼천포 화력발전소에서는 냉각수로 이용되고 방류되는 해수를 이용한 소수력 발전소가 건설되고 있다. 소수력 발전소는 발전량을 최대화하기 위해서는 규모를 크게 하는 것이 바람직하나, 소수력 발전소가 방류수로의 기능을 저해하지는 않는 범위에서 결정하여야 하기 때문에 적정규모를 결정하기 위해서는 수리학적인 고려가 필요하다. 본 연구에서는 현재 방류수로의 흐름특성 자료를 이용하여 3차원 흐름모형인 FLOW3D모형을 구축하고, 구축된 모형을 이용하여 소수력 발전소의 규모에 따른 방류수로 상류 지점의 수위 증가 양상을 예측하였으며, 발전소 건설에 따른 흐름변화 양상도 분석하였다 삼천포 소수력발전소 건설은 상류의 수위증가를 유발하며, 설계유량 156톤/초, 발전소 가동보 높이 3.8 m 기준에 대한 방류수로 Weir 상류지점의 수위는 4.97 m로 현 상태 4.32 m 보다 65 cm 정도 증가하는 것으로 파악되었다.

  • Small Hydro-Power (SHP) is an environmental friendly technology. Usually hydro power generation projects are viewed as constructing large dams and reservoirs but available new research and engineering techniques have helped hydro power generation without large dams and without large reservoirs. In India, there are several water installations, irrigation dams, canals, streams or running rivers not tapped to generate power. In these cases the existing system and facilities can help in generating power with less investment and time. This area is yet unexplored. Harnessing a stream for hydroelectric power is a major undertaking for the energy crises and the global issues to go green. In this technical note a potential site for mini hydro power plant nearby Shoolini University is identified and examined for the economic feasibility.
