摘　　要：超超临界技术是火电技术的发展方向。从技术和经济方面综合分析论证了我国发展超超临界机组的蒸汽参数选择和容量等级的问题。结论:在我国超超临界机组的起步阶段,选取25MPa/600℃/620℃的蒸汽参数是合适的,并论证了600MW、800MW和1000MW容量等级的机组各自的优缺点和适用条件。One of the development directions at thermal power-generating technique area is the technique of USC unit. It uses the method of technical and economic analysis to select the steam parameter and capacity grade. By analyzing we can conclude that it is appropriate to chose the steam parameter 25MPa/600℃/620℃ at the starting stage of USC unit. Also it demonstrates the advantage and disadvantage and application conditions of these capacities stage of 600MW, 800MW and 1000MW.
