摘要: 时间尺度是描述控制系统快慢特性的定量标尺,可作为控制器参数校正的依据。介绍了采用时间尺度校正的控制系统的结构、时间尺度校正参数的设置和调整方法。将时间尺度校正应用于某1 000 MW超超临界机组主蒸汽压力控制系统,给出了时间尺度校正的实现方法和调整步骤。该机组深度调峰及正常升降负荷过程的控制效果表明:时间尺度校正是控制系统变参数控制的一种简单有效的手段,可大大减少系统的调试工作量并缩短系统调试时间。

Abstract: The time scale is a ruler used to describe the speed characteristics of a control system and can be used to correct the controller parameters. The structure of the control system with time scale correction and its parameter setting and tuning method are introduced in this paper. The implementation of time scale correction and the tuning procedure applied to the main steam pressure control system of a 1 000-MW ultra-supercritical coal-fired power generation unit are presented. The performance of the main steam pressure control system in terms of deep peak regulation and large load variation shows that time scale correction is a simple but effective method for variable parameter control and has the potential to reduce the working load and shorten the time of on-site commissioning.

Key words: time scale, parameter correction, control system, tuning, ultra-supercritical unit
