5SHX1060H0003 3BHB020538R0001 3BHE024415R0101 GVC714A101 Cabinet Height Automatic Adjustment is mainly used to ensure that the gas cabinet operates in a safe height range. The system uses a fuzzy control algorithm to control the pressure stabilisation value of the pressure reducing station. The fuzzy control is based on the experience of actual experts to derive the pressure setting value under different working conditions, and the pressure reducing station is adjusted according to the results of the fuzzy algorithm with variable parameter pid.

5SHX1060H0003 3BHB020538R0001 3BHE024415R0101 GVC714A101 gas cabinet cabinet pressure is designed for 11kpa, the gas cabinet height is 75 metres, the gas cabinet height is normally controlled at 50 metres, at this time, the remote station regulator set the pressure at 11kpa. when the gas user’s gas dosage increases, the gas cabinet cabinet height will drop, when the gas cabinet height drops to 45 metres, the pressure is adjusted according to the fuzzy algorithm. When the height of the gas cabinet falls to 45 metres, the main station will change the set pressure to 11.6kpa, and then the height of the gas cabinet will rise with the rise of the pressure of the pipeline network. When the height of the gas cabinet rises to 50 metres, the main station will change the set pressure to 11kpa.

5SHX1060H0003 3BHB020538R0001 3BHE024415R0101 GVC714A101 When the height of the gas cabinet continues to rise to 55 metres, the main station will change the set pressure to 10.5kpa, and at this time, the height of the gas cabinet will fall with the decrease in the pressure of the pipe network. In this way, the cabinet height automatic adjustment using fuzzy control not only to ensure the gas pipe network pressure, so that the user gets a basic stable gas pressure; but also to ensure that the cabinet height of the gas cabinet, so that the gas gas source is not enough time to relieve the amount of gas network for a short period of time. This control effectively ensures the safety of production.
