By analyzing the construction cost and operation cost of conventional gas filling substation and hydraulic gas filling substation, an economic comparison between the two kinds of gas filling substations is made using the incremental internal rate of return.

Aimed at these peculiar conditions, this paper brings forward ideal running and operating conditions of secondary refueling station s compressors combined with material practice.

This paper analyses quantificationally the energy consumption in a CNG secondary fueling station driven by compressor and liquid pump through theoretic computation.

By analyzing the construction cost and operation cost of conventional gas filling substation and hydraulic gas filling substation, an economic comparison between the two kinds of gas filling substations is made using the incremental internal rate of return.

The standard gas filling station and hydraulic gas filling substation in Harbin City are compared and analyzed technically and economically.

Economic comparison of CNG standard fueling station and secondary fueling station;

This paper put forward a series of optimization scheme and sums up the calculation experience of tail water system transition process of the conventional power station,and provides reference for similar projects,based on the computation and analysis of Lechang Gorge Hydropower Station.
