| 摘 要： | 针对风电机组的调峰能力不足导致弃风问题依然突出,分析了系统热惯性对热电联产机组控制的作用,认为热电联产机组常规控制系统的发电负荷响应的跟随性存在较大时间的延迟,不能满足快速性响应要求,无法实时参与调峰,并提出了一种改进的控制方案来解决这一问题。通过Matlab/Stateflow仿真软件进行验证,仿真结果表明,改进后的控制方案显著优于常规控制方案,发电负荷响应指标响应快速,跟随性能良好,为热电联产机组参与电网调峰提供了先决条件。

| Abstract: | Aiming at the problem that abandoning wind is still prominent because of the insufficient peak load regulation capacity of wind turbine,the effect of thermal inertia of the system on the control of co-generation unit is analyzed.It is considered that the follow-up of generation load response of conventional control system of co-generation unit is delayed for a long time,which cannot meet the requirements of fast response and cannot participate in peak load regulation in real time,so an improved control scheme is proposed to solve this problem.Through the Matlab/Stateflow simulation software,the results show that the improved control scheme is significantly better than the conventional control scheme,the response of power load response index is fast and the follow-up performance is good,which provides the preconditions for co-generation units to participate in grid peak load regulation. |
