Energy storage bottle nozzle

How many nozzles are regulated in a compressed air energy storage system?

Only one nozzle is regulated in the optimal regulation process. The air storage pressure of the compressed air energy storage system gradually decreases during the energy release process. In order to make the turbine work efficiently in non-design conditions, it is necessary to adopt a reasonable air distribution method for the turbine.

How many nozzles should be regulated in an optimal nozzle governing method?

An optimal nozzle governing method should contain as few nozzles as possible. More throttle valves should be fully open for the optimal method. Only one nozzle is regulated in the optimal regulation process. The air storage pressure of the compressed air energy storage system gradually decreases during the energy release process.

How to optimize nozzle inlet pressure under variable woutput conditions?

Based on the RS model, the multi-island genetic algorithm (MIGA) is used to obtain the optimal nozzle inlet pressure under variable Woutput conditions with the maximum specific work ( w) as the optimization objective, and finally the optimization strategy of NG is derived.

How many nozzles are there under rated woutput conditions?

Under the rated Woutput conditions, the number of fully open nozzles, fully closed nozzles and regulated nozzles is 2, 1, and 1 under the BP of 10.0 MPa and 9.0 MPa, respectively. While the number of fully open nozzles, fully closed nozzles and regulated nozzles is 3, 0, and 1 under the BP of 8.0 MPa, respectively.

How many nozzles should a ng valve have?

Under the condition of satisfying the required Woutput, an optimal NG method should contain as few nozzles as possible, and more throttle valves should be fully open, that is, more nozzles with the inlet pressure as the BP. Simultaneously, only one nozzle is involved in the regulation process for each working condition.

Does nozzle inlet pressure change affect aerodynamic performance of ng turbine?

In studies of NG turbine, researchers have mainly focused on the mathematical modeling and control optimization methods in the NG process, but there are fewer studies on the effect of nozzle inlet pressure change on the aerodynamic performance of the turbine.
