Control Strategy and Experimental Research of 600 MW Supercritical Unit Load Management
In order to improve the capacity for variable load and resolve the conflicts within and outside the 600MW supercritical unit,the unit load management control strategy is adopted.Based on the actual operation,the external load requirements of the unit will be converted by the control center to actual load instructions,whose amplitude size and change rate are acceptable to the unit.Three tests on AGC,RB and load changes have been conducted simutaneously,and the test curve and data show that the strategy can improve the unit capacity for variable load and thermal efficiency,and quickly meet the power load requirements.
