Definitions

  • the present invention relates to an arrangement of controlling a compressor station for a gaseous medium in which the compressor station comprising turbine driven compressors is interposed between a source of a gaseous medium and a consumer.
  • the compressors have associated therewith controllable bypass conduit means so that the gaseous medium coming from the said source can selectively be passed through said compressors in succession or can bypass at least some of said compressors.
  • the present invention concerns an arrangement of and a method for controlling compressor stations for gaseous media using gas turbines as prime movers which. latter serve for compensating for the pressure drop in the conduits soas to maintain a minimum pressure at the-consumer.
  • the object of the present invention consists in providing the arrangement and control of a plant of the above mentioned type, as used for instance for supplyinga pipe line net for natural gas, in such a way that the driving gas turbines as well as the compressors during the time period during which the station is only under partial load, i.e. operates with reduced delivery, will work within the range of a favorable degree of efficiency and thus will operate economically.
  • each compressor station with a plurality of sets of turbocompressors which with regard to the direction of flow are arranged one behind the other and which can be bridged by bypass conduit means adapted to be closed.
  • Said turbocompressors are variable as to speed.
  • the turbocompressors are adapted, when the delivery drops and the bypass conduits are closed, to be controlled so that beginning with the last step they are one after the other reduced as to speed, then by opening the respective associat d bypass conduit are turned off as far as flow is concernedand are stopped.
  • the conditions are created for economically operating the station when only partial quantities are delivered, i. e. when a lower output is consumed than at maximum flow, since the delivery drops rapidly with a reduction in the throughflow.
  • FIG. 1 diagrammatically illustrates a natural gas supply line with a compressor station having three compressor sets. This figure also graphically shows the course of the pressure from the natural gas source to the consumer.
  • FIG. 2 is a graph illustrating the course of the obtainable fuel consumption with a compressor station arrangement according to the invention.
  • FIG.. 3 shows a compressor characteristic field explaining the operation of the compressor station according to FIG. 1.
  • the plant shown in the upper portion of FIG. 1 comprises a source 1 of natural gas, a supply line 2 leading to the compressor station, and an output line 4 leading to a storage container 5 to which the consumers are connected.
  • the compressor station 3 has three identical compressor sets each of which comprises a gas turbine 6, 7 and 8, a turbo-compressor 9, l0 ancl 11.
  • the compressors 9, 10 and 11 are arranged in series with regard to each other and are adapted to be bridged by bypass conduits l5, l6 and 17 respectively which are controlled by shut-off valves l2, l3 and 14.
  • all of the compressor sets are controllable individually as to their. speed.
  • FIG. 2 illustrates the course of the fuel consumption.
  • the fuel consumption B is plotted over the throughflow per weight.
  • Curve I shows the course of the fuel consumption within the range of partial delivery and with a pressure build-up for uniform end pressure at the compressor station. The irregularity of the curve is due to the successive switching-off and switching-on of the individual compressor sets.
  • Curve ll analogously shows the course of the fuel consumption when the pressure is built up to a station output pressure which will assure the minimum admissible pressure at the consumer end.
  • FIG. 3 shows a compressor characteristic field in which the pressure ratio p/p is plotted over the throughflow per volume at the compressor inlet V,.
  • the curve P represents the pumping limit of the compressor.
  • n, to n represent the lines of the same compressor speed, n, corresponding to a compressor speed of 100 percent.
  • Within the said characteristic field there are entered the lines of operation of the three serially arranged compressors.
  • the points a, b, c, d respectively refer to the operation with uniform starting pressure of the compressor stations, while the points A, B, C, D refer to operations with a minimum starting pressure at the station at which the end pressure at the consumer is still assured.
  • the index 1 always refers only to compressor 9, while the index 2 refers to the compressor 10, and the index 3 refers to the compressor 11.
  • the operational points of the first compressor stage will displace themselves accordingly to c,, C,
  • the operational lines of the second stage drop from b,, B, to a pressure ratio 1 in conformity with the points 0 C on the abscissa.
  • the operational lines of the first stage drop from points 0,, C, to the points (1,, D,.
