为利于传统能源和可再生能源发电的互补运行,有效利用可再生能源发电,实现火电企业的节能减排目标,并解决汽包炉单元机组控制作用滞后的局限,利用预见控制理论设计滚动的可在线调节的预见窗口,一方面为在线实时跟踪动态变化的优化调度策略制定的预发曲线提供技术支持,缓解传统和新能源发电调度中的矛盾问题;此外,结合预见控制可超前调节、逆输出控制可精确跟踪的优点,充分利用被调量给定值的未来信息作为前馈信号,使得控制作用能够超前给定值而变化,有效改善控制系统的跟踪性能。通过对300 MW燃煤汽包炉机组仿真实验验证系统的控制品质。
In order to facilitate the complementary operation of traditional energy and renewable energy power generation, make efficient use of renewable energy power generation and achieve the goal of energy saving and emission reduction of thermal power enterprises, and solve the limitations of the lagging control of drum unit unit, the predictive control theory can be used to design scrolling The forecasted window of on-line regulation can provide technical support for the online real-time tracking of the forecasted curve formulated by the dynamically-changing optimal scheduling strategy, and alleviate the contradictions in the traditional and new-energy power generation scheduling. In addition, the predictive control can be combined with the predictive control to reverse the output Control the advantages of accurate tracking, make full use of the future information of the setpoint to be measured as a feedforward signal, so that the control effect can change ahead of a given value and effectively improve the tracking performance of the control system. The control quality of the system is verified through the simulation experiment of 300 MW coal-fired drum boiler unit.
