摘要
本文针对煤粉制备系统为风扇磨直吹制的锅炉主汽压调节对象的特点:惯性大、给煤机给煤量与控制电流呈非线性等因素,利用原有常规仪表构造降维观测器,提供超前反馈信号,提高了系统抗内扰能力,改善了调节品质。设计中使系统有较多的整定参数,以兼顾不同的性能指标。已在某电厂实际应用,并得到验证。
For direct-fired-boilers with fan mill in thermal power plant, the automatic regulation of steam pressures remains long time a problem which has not been solved satisfactorily. But the solution of this problem is of great practical significance to the safe and economical operation of such boilers. This paper presents the investigation results of this problem, carried out in a power plant.
