电网自动调频和经济运行是电网调度自动化的重要任务,因此研究电网正常运行时的负荷扰动,可使电网的发电出力跟踪实际的负荷变化,保持电网频率及电钟误差在规定的范围,并保持电网的低运行费用,为电网的经济运行服务.电网自动发电控制过去称为自动调频和经济运行,有着两种实现体制,即所谓分散型和集中型,它们各有利弊,然而它们的指导思想,都是建立在古典控制理论基础上,按经济运行准则控制发电出力.
Therefore, the study of the load disturbances during normal operation of the power grid can make the power generation of the power grid track the actual load changes, keep the grid frequency and the clock error within the specified range, and maintain The low operating cost of the grid serves the economic operation of the grid.The grid automatic generation control, formerly known as auto-tuning and economic operation, has two implementation regimes, namely decentralized and centralized, each with its advantages and disadvantages, but their guiding ideology , Are based on the classical theory of control, according to the rules of economic operation control power generation.
