摘要

针对大唐马鞍山当涂发电有限公司一期超临界2×660 MW机组控制系统存在的主蒸汽压力波动大、对煤质频繁变化适应性差、负荷响应慢等问题

对机组协调控制系统的负荷指令与压力设定、锅炉主控、汽轮机主控、一次调频、给水、燃料等控制回路进行了优化。控制系统优化后

机组稳态下负荷偏差减小

在变负荷过程中主蒸汽压力波动较小

在稳定负荷下主蒸汽压力与设定值偏差较小

控制品质显著提高。

Abstract

Directing against the problems existing in control system of supercritical 2×660 MW units in the first-phase project of Datang Ma'anshan Dangtu Power Generation Co Ltd

such as large fluetuation of the main steam pressure

bad suitability to the frequent change of coal quality

and show response to the load etc.

the load command and the pressure set value in the coordinated control system of units

the master control of boiler

the master control of steam turbine

and the control eircuits of primary frequency modulation

feed-water

and fuel etc have been optimizaed.Results of test show that the load deviation in stable state of units after optimization of the control system has reduced

the fluctuation of main steam pressure is smaller in the process of load change

the deviation between main steam pressure and the set value is smaller under stable load

the control quality has been remarkably enhanced.
