Abstract

Abstract: Since the domestic 600MW supercritical unit was put into operation, its operation is not so stable, and unplanned outage was happened many times. The current situation of automatic control of the supercritical unit was analyzed. Aiming at automatic adjustment of main steam temperature, some improvement suggestions were put forward, which causes the control of main steam temperature to be more fast and accurate, and the operation reliability and safety of the supercritical unit were increased.

Key words: supercritical unit, main steam temperature, automatic control, optimization
