The efficiency improvement of the automation transformation of the compressed air energy storage expansion machine production line has no fixed value, and is affected by the technical links involved in the transformation and the basic conditions of the original production line. The existing public research and case studies can refer to the efficiency improvement space in the range of 3.5% to 13.2% (under specific working conditions).
1, Referenceable improvement data and applicable conditions (1) Efficiency improvement of scale upgrade transformation
Regarding the automation upgrade of compressed air energy storage systems, based on a 100MW system, the efficiency of a 300MW system can be improved by 3% to 5%. (II) Efficiency improvement of channel regulation modifications
According to the research data published by the Institute of Engineering Thermophysics, Chinese Academy of Sciences, for the automatic transformation of the installation angle of the static blade of the expander regulating channel:
When the benchmark pressure is 10.0MPa, compared with the traditional throttling valve method, the maximum specific power increase reaches 13.2%; Compared to the design installation angle, the increase is 4.0%
When the benchmark pressure is 8.0MPa, compared with the traditional throttling valve method, the maximum specific power increase reaches 4.1%; Compared to the design installation angle, the increase is 3.5%
