为了解决目前火电厂热工调试缺乏先进的控制方法、无法在生产现场进行应用的难题.基于虚拟DPU技术研发了热工调试系统,该系统具有良好的稳定性和可扩展性,可用于热工组态的调试.火力发电厂要求较高的主汽温控制精度,由于主汽温存在大惯性和大延迟特性,传统的PID控制策略难以取得较好的控制效果,不能满足生产的需要,需要研究高精度的主汽温控制策略.在该热工调试系统上进行了主汽温控制策略优化研究,研究结果表明:改进后的控制方法具有良好的控制品质,同时也说明热工调试系统能够满足热工调试的要求,为进一步开展火电厂自动控制策略研究提供了解决方案.
In order to solve the current thermal power plant commissioning lack of advanced control methods, can not be applied in the production site problems.Virtual DPU technology based on the development of thermal debugging system, the system has good stability and scalability, can be used for thermal Because of the large inertia and large delay characteristics of the main steam temperature, the traditional PID control strategy is difficult to achieve good control effect, can not meet the needs of production, need The main control strategy of main steam temperature is optimized on the thermal debugging system.The results show that the improved control method has good control quality and also shows that the thermal debugging system can Meet the requirements of thermal debugging, and provide a solution for further research on the automatic control strategy of thermal power plant.
