摘要
主要研究新型实用非线性自抗扰控制技术(ADRC)在火电厂燃烧控制系统中的应用。针对火电厂燃烧控制系统的大滞后、大惯性以及动态特性随工况变化的不确定性等特点,提出了自抗扰燃料量控制方案。采用600MW超临界燃煤机组的燃烧控制系统为被控对象,在电厂热工过程控制实时仿真平台STAR-90上建立模块化的控制器,分别进行了降负荷、加10%扰动和RB试验。试验结果表明,用ADRC技术建立的燃料量控制系统与PID控制系统相比,ADRC控制系统具有更好的控制品质和抗干扰性。
Mainly studied was the application of novel and practical non-linear active disturbance-resistant control(ADRC) technologies in combustion control systems of thermal power plants.In the light of such specific features of combustion control systems of thermal power plants as a big hysteresis,large inertia and uncertainty of dynamic characteristics changing with operating conditions,an active disturbance-resistant control scheme was presented.With the combustion control system of a 600 MW supercritical coal-fired unit serving as a controlled object,a modular controller was established on a real-time simulation platform STAR-90 for the thermodynamic process control of power plants,and a load reduction,addition of 10% disturbance and RB(Run Back) test were performed respectively.The test results indicate that compared with a PID(Proportional,Integral and Differential) control system,a fuel quantity control system based on ADRC technologies boasts a better control quality and disturbance-resistant ability.
