Excellent control method, comprising three and less than three systems for running equipment under nominal situation and other emergency work conditions, especially
Than relatively hazardous or special operating mode or the operation method under special operating mode.
Background technology
System comprising three operation equipment, for example：Three oil feed pumps of boiler fuel oil pump house system, circulation
The many systems of three condensate transfer pumps of three water circulating pumps and condensate system etc., these are all critical systems, must
Must ensure which safely and steadily runs, normal high load working condition, typically all two equipment operations, remaining equipment sparing,
But in actual production running, there are many small load conditions, only need to run an equipment just, remaining two equipment
It is standby, so both meet production needs, save equipment and the energy again.Current system great majority only consider the reality of " dual-purpose is standby "
Border operating mode, often ignore outlet main-piping pressure it is low or run per platform equipment outlet pressure it is low when, how protection system, Yi Ji little
The actual operating mode of " one is standby with two " under load condition, even if considering, the interlock logic of whole system nor too comprehensively,
Or the very very complicated that logical relation is done, in different control systems, often because functional device the execution time or
The factors such as execution cycle, and the accuracy of result is affected, causing in actual motion, the connection between equipment opens failure or joins by mistake
Other equipment, or even the phenomenons such as system chaser are caused, or directly manually operated etc., it is not to cause inefficiency, wave
Take resource, exactly affect the safe and stable operation of whole system, greatly reduce system automation degree.
The content of the invention
The present invention is directed to above-mentioned problems of the prior art, there is provided a kind of optimum control side of three operations equipment
Method, is the optimal control policy of the system comprising three and less than three operation equipment.Its purpose is to guarantee system in office
Can require to carry out safe and stable, reliability, economy, efficient operation according to actual motion under what operating mode, improve automatization's journey
