摘　　要：在以新型绿色能源的快速发展为代表的新能源革命的发展进程中,从现有火电机组重要过程控制回路实现深度调峰、快速调频性能的角度,传统的比例积分微分(proportional-integral-derivative,PID)控制技术难以再适应。为此,发明工程最速控制器(engineering fastest controller,EFC),显著提高反馈控制性能,适应目前新型绿色能源快速发展的客观需要。但是构造EFC的工程最速比例积分(engineering fastest proportional-integral,EFPI)控制器存在控制性能相对不高的问题,EFPI难以单独运用,需要针对EFPI存在的问题进行改进;因此提出加速型工程最速跟踪滤波器(acceleration engineering fastest tracking filter,AEFTF),采用AEFTF构造出加速型工程最速比例积分(acceleration engineering fastest proportional-integral,AEFPI)控制器,实现一种工程上的加速型最速控制性能,相对EFPI,有效提高了控制性能。通过将AEFPI与EFPI、最优PI(optimal proportional-integral,OPI)控制进行对比,验证了AEFPI的控制性能明显优于EFPI、OPI。所给出的典型工程应用案例证明:与PI控制相比,AEFPI显著提高了现有火电机组的过程控制性能。AEFPI是EFC的继续深入发展,AEFPI、EFC的快速发展为新能源革命提供动力。In the development process of the new energy revolution represented by the rapid development of new green energy,from the perspective of the existing thermal power unit process control,the traditional proportional-integral-derivative(PID)control technology is difficult to adapt.Researchers have invented an engineering fastest controller(EFC),which significantly improves the feedback control performance and meets the objective needs of the current rapid development of new green energy.However,the engineering fastest proportional-integral(EFPI)controller that constructs EFC has the problem of relatively low control performance.EFPI is difficult to use alone,and needs to be improved for the problems existing in EFPI.An accelerated engineering fastest tracking filter(AEFTF)is proposed.AEFTF is used to construct an accelerated engineering fastest proportional-integral(AEFPI)controller,which effectively improves the control performance compared with EFPI.By comparing AEFPI with EFPI and optimal proportional-integral(OPI)control,it is verified that the control performance of AEFPI is significantly better than that of EFPI and OPI.The given typical engineering application cases prove that compared with PI control,AEFPI significantly improves the process control performance of existing thermal power units.AEFPI is the continuous and in-depth development of EFC.Behind the rapid development of AEFPI and EFC,it represents the development process of promoting the new energy revolution.
