超临界火电机组运行灵活性提升控制策略研究及应用
Research on and Application of the Control Strategy for Flexibility Improvement of Supercritical Fossil-Fired Power Units
摘要
Abstract
Along with the increasing of new energy generation projects and long distance power supply volume beyond the area,the power supply structure of power grids has undergone fundamental changes,which brings about growing pressure on peak load regulation.Therefore,the modification on the flexibility of automatic control is required.In this paper,based on the analysis of the characteristics of the power grid AGC instructions and the study on the control characteristics of the supercritical units,a series of control strategies are proposed in accordance with the requirements of power grids to improve the load response rate of the unit under the condition of large loads,avoid the impacts of the slight fluctuation of the AGC commands on the unit control and enhance the stability of the reheat steam temperature control.The practical application proves that the optimized coordinated control system can maintain the stability of major thermal parameters and meet the requirements of the power grids for the enhancement of the flexibility of the unit operation.关键词
