Optimization Strategy for Coordinate Control System of 700 MW Supercritical Thermal Power Unit
摘要
为提高机组的协调控制调节品质
对原控制系统策略的不足进行分析
从锅炉主控、汽机主控、给水调节、燃料调节、一次风压调节、磨煤机风门控制等方面进行优化
满足发电机组的AGC负荷调节的速率及精度要求。优化后增强了锅炉对煤种变化的适应能力
机组主要参数调节品质优良
机组安全稳定经济运行水平得到提升。
Abstract
In order to improve the controlling quality of the coordinated control system of the unit
optimization work based on the analysis of the deficiencies in the original system control strategy on several aspects such as the main control system of boiler and steam turbine
feed water automatic regulation system
fuel master
primary air pressure adjustment
the air damper control of the coal mill was done to meet the requirements of adjustment rate and accuracy of the AGC load of the generating units. After optimization
the adaptability of boiler to the change of coal is enhanced
and the safety and stability of the unit is improved.
