基于自校正PID控制的单元机组CCS的仿真研究

Based on self-tuning PID control unit plant CCS simulation

单元机组协调控制系统是火力发电厂的控制重点,在工程实际中,应用最广泛的控制规律为PID控制。本文提出一种自校正PID控制器,它不仅可以消除外扰的影响,而且可以应用于多变量系统解耦。本文以神头第二发电厂500MW机组模型为例,将自校正PID算法作为子控制器进行仿真研究,结果表明自校正PID控制比常规PID有更好的鲁棒性和抗干扰性。

Unit Coordinated Control System is the emphasis for power plant.In practical engineering,the PID control is used most widely.This paper presents a self-tuning PID controller,it can not only eliminate the impact of outside interference,but also be used in multivariable decoupling system.In this paper,We take 500MW unit model of the second power plant of shentou for example,and do simulation research that the self-tuning PID control algorithm as a sub-simulation.The results show that self-tuning PID control has better robustness and immunity than the conventional PID.
