Abstract: This article outlines the development and use of tidal energy, specifically, the exploitable tidal energy and the situation of its use in China and introduces the first large bidirectional tidal experimental power station now in China. The Jianxia Station, which is in the northern part of Leging Bay near Werling County, Zhejing Province, is one of China's key research projects. There are five installations of two types for a total capacity of 3200 kw. All use bulb turbines appropriate for low head power stations. One type of installation, No. 1 and No. 2, has planetary gear trains. Another type of installation is the directly driven type. Since May 1980, when it went on line, unit No. 1 has operated in good condition. All five units were in operation by January 1986 and the engineering plan of Jiangxia was also completed. The article illustrates the operational characteristics and structure of tidal water turbines No. 1 and No. 2.
