This paper presents an optimization of the interlock logic control of No.1 600 MW subcritical air-cool unit of Guohua Jinjie Energy CO.
Ltd.The interlock logic design core it revealed has a control of three feed water pumps that are standby for one another and can all be started up from section A or B of the bus-bar.Tests on the electric pump interlock were conducted under the different conditions
one is with one pump in operation while the other was standby under 59% load
and the other is that two pumps were in operation while one pump is standby under 100% load.The test results have proved that the logic design after optimization is rational and correct.
