Small Hydroelectric Power Development in China

摘要

The small hydroelectric development in China is extensive, with more than 90,000 units, but represents a very small resource in terms of total electricity generation (or as little as 4%). In the rural areas, however, small hydro is an important tool for modernization and represents a substantial percentage (30%) of the electricity. Its characteristics - simplicity, reliability, and low cost are ideal for isolated underdeveloped areas. Good turbine design is largely an empirical science. The Chinese experience in developing technology for for a large variety of operating conditions has provided an empirical basis for good designs. Their small turbines and accompanying control mechanisms thus appear to be competitive in the American market. It is not obvious that other technology, especially on the electrical side, has advantages for the American market. It appears that the Chinese emphasis on small hydroelectric development, in parallel with large central development, will continue in the future. Technical development, especially in the small standardized turbine area, should continue as well. (ERA citation 05:034624)
