联合循环燃气轮机低负荷运行模式探讨与分析

Discussion and Analysis on Low Load Operation Mode of Combined cycle Gas Turbine

联合循环燃气轮机启停响应迅速,具有良好的灵活性以及较高的工作效率,因此在电厂中应用广泛,深受我国市场青睐。鉴于此,文章以某发电厂多轴联合循环燃气轮机机组为例,首先分析了该机组在低负荷阶段运行的特征以及机组特点,然后在机组原有的运行方式以及协调逻辑上对联合新欢燃气轮机的负荷分配方式进行了调整与优化,最后借助旁路与汽机的配合,在保障联合循环燃气轮机机组稳定性的基础上实现了发电效率以及经济效益的最大化,以期能给相关结构或者类似研究起一定的借鉴作用,提升联合循环燃气轮机机组的性能。

The combined cycle gas turbine can start and stop response quickly, has good flexibility and high working efficiency, so it is widely used in power plants, favored by the Chinese market. In view of this, the paper analyzes the characteristics of the gas turbine unit, firstly analyzes the operation and the characteristics, and then realizes the maximization of the power generation efficiency and economic benefit on the basis of ensuring the relevant structure or similar research, and improves the performance of the combined cycle gas turbine unit.
