소수력자원은 신재생에너지 중에서도 온실가스 배출량이 가장 적고 에너지밀도가 매우 높기 때문에 개발할 가치가 큰 청정부존자원으로 평가되고 있다. 본 연구는 프란시스 수차의 국산화 개발 연구로써 프란시스수차 외형설계에 필요한 기본사항과 제작, 프란시스수차의 설치 및 시운전, 프란시스수차의 성능시험을 수행하였다. 이에 대한 분석 결과, 개발된 프란시스수차는 기계적인 성능과 수력학적인 성능면에서 만족할 만한 결과를 보여주어 프란시스수차의 상용화에 대한 기반이 마련되었다.

프란시스수차의 경우 다른 종류의 수차보다 효율, 설치 및 운영면에서 많은 장점을 갖고 있으며 표준화를 통하여 가격을 크게 낮출 수 있기 때문에 우리 나라의 소수력발전입지에 적용하기가 매우 좋은 수차라고 할 수 있다. 수차설계자료를 외국의 수차제작사들이 공개하지 않으며, 국내의 수차설계경험의 부족으로 인하여 수차설계기술이 확립되지 않은 상황에서 국내 소수력자원특성에 적합한 프란시스수차의 국산화개발 기술이 확립되었다.

The Francis type hydro turbine with vertical axis has been designed and analized for hydraulic performance verification. The guide vane angle of turbine casing were designed to be varied according to the condition of head and flowrate. When the changes in flowrate and output were comparatively large, the efficiency drop were small, so the efficiency characteristics and stability of the entire operating condition were maintained in good condition. These results showed that the developed hydro turbine in this study will be suitable for small hydro power stations with medium and high head such as agricultural reservoirs and large dam.

As a key component of a Francis turbine facility, the runner performance plays a vital role in the performance of the turbine. It is effective and successful to design a Francis turbine runner blade with good performance by one dimensional hydraulic design method. On the basis of one dimensional hydraulic analysis, there are a lot of parameters of the internal flow passage shapes determined by experience. Among those parameters, the effect of port area of blade on the performance of a Francis turbine is investigated in this study. A given Francis turbine model was selected for investigating the port area of blade on the performance. The result shows that the effect of port area of runner blade on the outflow angle from runner passage on the performance is quite significant. A correct exit flow angle reduces the energy loss at draft tube, which has the best efficiency of the turbine model.

The hydraulic performances of a Francis turbine which had been designed and tested by IMHEF were calculated with a commercial code and compared with the IMHEF test results. The non-dimensional specific speed of the turbine is 0.5, the runner exit diameter 0.4m and maximum efficiency 93.1% respectively. To make the calculation of the turbine more exact, the stay vanes, the guide vane, the runner and the draft tube were calculated simultaneously. The calculation results gave a quite good agreement with the IMHEF test data, and therefore it is expected that the present calculation technique will be utilized for the hydraulic design of efficient Francis turbines.
