Abstract

This graduation thesis undertakes parts of work in the design of powerhouse of hydropower station in hydropower construction. The design is based on the original information and the local weather. The main contents are as following: the place of the hydropower station, the entire layout, the choice of the hydraulic turbine type, the size of the volute, the size of the draft tube, the Dimension of the powerhouse of hydropower station, the arrangement of accessory equipment, and drawing the plan and section drawn.

The station adopts the developing of diversion type power, the station has three axis-flow sets, whose single-machine capacity is 6 MW. The station can make sure that the output is

4.7MW and the average of output is 869.8 million in recent years, and the available hours are 4832 hours.

The station designing includes a 13-meter-long water head and a generator with 6000KW single-machine capacity. There are three machine sets, whose total installed capacity are 180MKW.

Key words: single-machine capacity, installed capacity, diversion type power, generator, hydraulic turbine.
