Tidal Energy
Research on tidal power generation is conducted in the countries including France, former Soviet Union, Canada, China and England. Its technology has been developed to the ripest among that of ocean energy, and the utilization scale has been the largest one. The total installed capacity of tidal power stations in the world hits 265MW, details please refer to Table 1.

China is the country that has built the most tidal power stations in the world. Nearly 50 sets of tidal power station have been built from 1950s to 1970s. But according to the statistics in early of 1980s, only 8 sets of power stations were being operated in normal condition. Jiangxia power station is the largest tidal power station in China, which has been put into operation for nearly 20 years, but still cannot match up to the original design.
Research on Jiangxia power station was listed into the major technical projects needed to tackle in the period of “the Sixth of Five Year” in China. The project investment was 1,130 million Yuan. It has started the construction from 1974. The first generator sets of 500kW started its generation in 1980. The project was completed in 1985, which was installed one set generator of 500kW, one set of 600kW and 3 sets of 700kW with the total capacity of 3.2MW. The power station belongs to single-reservoir and two-function type, with which the area of reservoir is 1.58´106m2, and it was designed to generate 10.7´107kWh yearly. In 1996, the annual net generating capacity was 5.02106kWh, equaling half capacity of the design. The main reason is that it has difference between the design state and the actual state of the operation. Furthermore, the operation guarantee of the sets and operation control method should be upgraded. But general speaking, Jiangxia power station is successful which provides more comprehensive technology for construction of tidal power station in China, and as well as accumulates abundant experience for operation, management and multi enterprise of tidal power station.
