Abstract： With the continuous growth of the national economy and the continuous innovation of science and technology， the construction and development of China's electric power industry has made a qualitative leap. "Two-on-One" gas-steam combined cycle unit， as an advanced power generation technology， when widely used in the power industry， has created a great value. The most remarkable feature of the "Two-on-One" gas-steam combined cycle unit is that it can start and stop quickly， efficiently and safely， which can help thermal power plants to maximize thermal efficiency， reduce pollution emissions， and realize the harmonious and stable development of ecological and economic construction. In view of the related reasons for the deviation of the control effect of the "Two-on-One" gas-steam combined cycle unit， this paper will further carry out in-depth research and discussion， in order to provide scientific reference for people in the same industry.

Keywords： "Two-on-One" gas-steam combined cycle unit; control strategy; system

引言

当前是一个科学技术创新时代，我国燃气轮机技术完善发展要与时俱进，跟上时代前进的脚步。二拖一燃气-蒸汽联合循环机组实质指的是将2套先进的燃气轮机、1台汽轮轮机有机结合在一起，基于余热锅炉系统运行作用下，帮助市场燃机电厂全面提升热效率，确保在最低成本下创造出最大的经济效益。与西方发达国家相比较，我国二拖一燃气-蒸汽联合循环机组性能控制水平较低，有待相关工作人员进行深入研究，科学有效采取优化措施，全面提升机组运行质量和效率，并且实现机组节能创新改造目标，为燃机电厂节能更多的能源。
