The 21st century , China's power industry is moving towards an efficient , energy-saving , environmental protection , energy use and environmental and sustainable development as a strategic goal of the development stage , important sign is the rapid development of ultra-supercritical units . The development of ultra-supercritical power generation technology to create new economic growth point , the strategic choice for the sustainable development of China's power industry . The main steam temperature control is directly related to the safe and economic operation of the unit , this subject carried out the characteristics of the main steam temperature control system of ultra-supercritical unit and its control strategy research . Thermal power plant steam temperature control is a study of the problem for many years , with the growing popularity of DCS system , cascade PID control strategy has become a classic and is widely used . However , for ultra-supercritical unit , but it falls short of actual control effect . The topics in the analysis of the superheated steam temperature regulating controlled object task control difficulty , based on design principles as well as static and dynamic characteristics , respectively, with the fuzzy control and predictive control Superheat steam temperature control , this theory analysis and simulation study and found that both have significant advantages , but there are obvious shortcomings , both reasonable combination of other applied to the control system . Therefore , the design of a fuzzy generalized predictive control algorithm based on the T - S model can adapt to the changes in the working conditions of the superheated steam temperature control and interference effects . Compared with the traditional control algorithm , the algorithm has the advantages of good robustness, simple, easy - to - line adjustment . Its algorithm is applied to the main steam temperature control of the ultra-supercritical unit , simulation results show that the control system regulating quality satisfactory and steady changes in the amount of control , and has good robustness and immunity , higher engineering practical value.
