The operation tactics  of 670MW supercritical oncethrough boiler  under AGC (R) pattern

Abstract

Abstract: Abstract:When the 670MW supercritical unit of Huadian Weifang Power Generation Company Limited operated under AGC(R) pattern, the larger fluctuation of the unit load leaded the unit parameters to be unstable, and the unit had to exit from AGC(R) pattern frequently. Aiming at this problem, the possible reasons were analyzed, and some targeted measures, such as to control intermediate point temperature, to adjust the coal quantity in ignition stage and last stage of load variation and so on, were adopted. So the operational reliability and economic efficiency of large unit under AGC(R) pattern were improved.

Key words: Keywords:supercritical oncethrough boiler, automatic generation control (AGC), countermeasure
