Abstract: China is one of few countries in the world main power production of which is thermal power generation. China is rich in coal resource, and this determines that in longer term the main installed units of our country will be thermal power units. But the power source structure is not all rational. Aiming at this situation, hereafter, in development of electric power construction, must optimize the thermal power generation development, must vigorously develop the clean power generation technology, promote the integration construction of coal, electricity and harbor, and in coastal areas, which is rich in water and poor in coal, must introduce and construct 1300MW unit, and introduce the optimal ultrasupercritical single reheat generation technology, and those will helpful for realization of sustainable development of domestic electric construction.

Key words: ultra-supercritical1300MW unit, thermal power generation, introduce, optimization
