Abstract: The research of ultra-supercritical power generation technology was introduced, especially State Development and Reform Commission significant project “research of 600 MW supercritical thermal power unit” and 863 plan (“Tenth Five-year Development Plan”) ”ultra-supercritical coal-fired power generation technology”. Research results of the two projects realized leap development of ultra-supercritical coal-fired power generation technology. Further more, present situation of generating set manufacturing industry and development scale of ultra-supercritical units were introduced, and the leading direction in coal-fired power plant in China was pointed , which is the ultra supercritical electricity generation technology.

Key words: ultra supercritical unit, coal-fired power generation technology, development, present situation
