摘要

分析了使火电机组协调控制品质较差且不能达到自动发电控制(AGC)性能考核指标的原因。采用分项动态自适应前馈技术和基于一次调频功能的AGC控制方案对机组协调控制系统进行了优化

优化后的机组协调控制系统应用于国投天津北疆电厂1号超超临界1 000MW机组中。结果表明

机组在500～1 000MW之间以20MW/min的速率AGC变负荷时

机组负荷动、静态偏差均小于1%

主蒸汽压力偏差小于0.4MPa

主蒸汽温度偏差小于6℃

微过热点蒸汽温度偏差小于10℃

AGC综合指标系数KP显著提高。

Abstract

The reason for poor quality of coordination control system(CCS) and the failure of achieving the index of automatic generation control(AGC) performance examination was analyzed.Partial dynamic adaptive feedforward technique and primary frequency modulation based AGC control method were adopted to optimize the unit coordination control system.The application of optimized coordination control system on an ultra supercritical 1 000 MW power unit showed that

the unit changed its load at rate of 20 MW/min from 500 MW to 1 000 MW.The dynamic and static deviations of the unit load were both less than 1%.The deviation of main steam pressure was less than 0.4 MPa

and that of the main steam temperature was less than 6 ℃.The deviation of slight-superheat steam temperature was less than 10 ℃

the aggregative indicator of the AGC was improved dramatically.
