热力站智能调节器设计

摘要

文中提出了适合我国热力站系统的自动控制方案，介绍了相应的智能调节。该智能调节器实时跟踪气候温度变化，优化热力站供热设定值，在常规PID基础之上，采取不完全微分、被控变量微分、非线性输出限制、比例增益自适应修正等改进措施，使热力站控制系统达到优化运行状态。%This paper presents an automatic control method adapted to our Country's thermal power station and the corresponding intelligent controller.The controller can follow the change of environment temperature on the real time and optimize the set-point value of the thermal energy supplied.On the basis of conventional PID control method,the partial derivative,the controlled varies derivative,the nonlinear restricted output,the proportional gain adaptive revise etc.are used together to make thethermal power station system running in optimal state.
