[Abstract]:The purpose and the main meaning of popularizing and implementing optimal load distribution in power plant is that the AGC automatic power generation control (Automatic Generation Control) of thermal power plant is used to connect the power grid energy management system with the generator unit control system in essence. As an important control system to balance the load of generating set and power grid, factory level AGC can ensure the stability and efficiency of power network, improve the efficiency of power generation, and ensure the coordinated and stable operation of unit equipment. Finally, the sustainable and efficient development of power grid and power plant is realized. This paper analyzes the feasibility of practical application of AGC system in thermal power plant. By consulting the relevant research literature at home and abroad, the feasibility analysis is carried out theoretically, and then the test and simulation environment is established. The data of load distribution of AGC system at plant level are collected through simulation system, and the feasibility of the test is further combined with the actual project to carry out practical demonstration. Finally, it is proved by the actual project that the whole plant mode of AGC can effectively improve the deficiency of the traditional AGC system in dispatching load, which can be used as a powerful assistant to the AGC of power grid and realize the high efficiency and sustainable economic benefit. At the same time, it also shows that the coal consumption curve of the unit must be relatively accurate as the soul of the factory level AGC system. If the accurate coal consumption curve can be combined with the factory level AGC, the win-win situation of energy saving and dispatching of power grid and power plant will be realized.
