Engineering Research On Predictive Control Technology In Intelligent Power Generation

As of March 2022,China’s installed power generation capacity has exceeded 2.4 billion kilowatts,and the proportion of thermal power generation capacity still ranks first.However,thermal power generation has the disadvantages of high pollution and high energy consumption,which runs counter to the country’s "dual carbon "strategy,so the reform of the power system is urgent.With the development of society,the concept of sustainable development has emerged as the times require.This concept includes some characteristics such as green,energy conservation,emission reduction,and safety.How to integrate these new ideas and concepts into the power system has become a key topic of research.With the introduction of the new concept of intelligent power generation,it has played a guiding role in the reform of the power industry.In the field of control,intelligent power generation requires increasingly high automation quality of the system,and traditional PID control methods cannot meet the control requirements of current power systems.Therefore,it is necessary to introduce intelligent algorithms with higher control quality to be applied in the actual power generation process.Compared with other intelligent control algorithms,predictive control does not rely on accurate mathematical models,and has higher control accuracy for complex industrial models.In particular,generalized predictive control(GPC),with its good control quality and robustness,provides ideas for improving control methods in power systems.This article will improve the GPC algorithm to reduce the amount of computation in its calculation process,and improve the anti-interference ability and robustness of the system,so that it can play a better role in engineering;This paper combines GPC with traditional PID control to form a proportional integral generalized predictive control algorithm(PIGPC),and compares the simulation results of PIGPC with GPC and PID.The results show that PIGPC exhibits better control quality than GPC and PID;Finally,combined with the circulating fluidized bed selective catalytic reduction(SCR)denitration control system in thermal power plants,a PIGPC cascade control strategy was designed,and its control performance in denitration control was analyzed.Compared with traditional PID cascade control,a denitration control system engineering verification strategy was presented based on industrial practice.
