摘要: 为满足电网对机组频繁和快速的启停的需求,对某电厂2×600 MW超临界发电机组启动过程的节点进行调整,包括采用适度开启高压调节阀、优化蒸汽参数和调整凝汽器真空等措施,优化机组的运行方式。采用这一优化方式,提高了机组启动安全性及机组启动成功率,缩短了机组启动时间,节约了启动燃油量及厂用电量,不仅满足了电网的需求,也为电厂创造了良好的经济效益。

Abstract: To meet the requirements of frequent and quick startup of units by the power grid, the startup procedures are adjusted by optimizing the operation pattern of two 600-MW supercritical units of a power plant, which includes moderate opening of high-pressure regulating valve, optimization of steam parameters and condenser vacuum, etc. Through the implementation of the optimized procedures, the safety and the success rate of the unit startup are improved and the startup duration is shortened, which not only meets the requirements of the power grid, but also produces good economic benefits for the power plant.

Key words: 600 MW, supercritical unit, startup optimization, energy saving and consumption reduction
