Claims (8)

1. Способ ограничения критического параметра компрессора или группы компрессоров с помощью первого выходного сигнала главного регулятора, управляющего производительностью компрессора или группы компрессоров, и выходного сигнала ограничивающего регулятора, управляющего рециркуляционным клапаном или клапанами, включающий: а) формирование второго выходного сигнала главного регулятора одновременно с первым выходным сигналом и б) изменение выходного сигнала ограничивающего регулятора с помощью второго выходного сигнала главного регулятора.1. A method of limiting the critical parameter of a compressor or group of compressors using the first output signal of the main controller that controls the performance of the compressor or group of compressors, and the output signal of the limiting controller that controls the recirculation valve or valves, including: a) generating a second output signal of the main controller simultaneously with the first output signal and b) changing the output signal of the limiting controller using the second output signal of the main regulator Yator. 2. Способ по п. 1, в котором второй выходной сигнал главного регулятора изменяет выходной сигнал ограничивающего регулятора только тогда, когда он превышает пороговые значения ограничивающего регулятора. 2. The method according to claim 1, in which the second output signal of the main controller changes the output signal of the limiting regulator only when it exceeds the threshold values of the limiting regulator. 3. Способ по п. 1, в котором изменение выходного сигнала ограничивающего регулятора достигается путем сложения второго выходного сигнала главного регулятора с уставкой ограничивающего регулятора. 3. The method according to claim 1, in which the change in the output signal of the limiting controller is achieved by adding the second output signal of the main controller with the setting of the limiting controller. 4. Способ по п. 1, в котором изменение выходного сигнала ограничивающего регулятора достигается путем сложения второго выходного сигнала главного регулятора с выходным сигналом ограничивающего регулятора. 4. The method according to p. 1, in which the change in the output signal of the limiting controller is achieved by adding the second output signal of the main controller with the output signal of the limiting controller. 5. Устройство для ограничения критического параметра компрессора или группы компрессоров с помощью первого выходного сигнала главного регулятора, управляющего производительностью компрессора или группы компрессоров, и выходного сигнала ограничивающего регулятора, управляющего рециркуляционным клапаном или клапанами, содержащее: а) средства формирования второго выходного сигнала главного регулятора одновременно с первым выходным сигналом и б) средства изменения выходного сигнала ограничивающего регулятора с помощью второго выходного сигнала главного регулятора. 5. A device for limiting the critical parameter of a compressor or group of compressors using the first output signal of the main controller that controls the performance of the compressor or group of compressors, and the output signal of the limiting controller controlling the recirculation valve or valves, containing: a) means for generating a second output signal of the main controller with the first output signal and b) means for changing the output signal of the limiting controller using the second output th main regulator signal. 6. Устройство по п. 5, в котором второй выходной сигнал главного регулятора изменяет выходной сигнал ограничивающего регулятора только тогда, когда он превышает пороговые значения ограничивающего регулятора. 6. The device according to claim 5, in which the second output signal of the main controller changes the output signal of the limiting regulator only when it exceeds the threshold values of the limiting regulator. 7. Устройство по п. 5, в котором изменение выходного сигнала ограничивающего регулятора достигается путем сложения второго выходного сигнала главного регулятора с уставкой ограничивающего регулятора. 7. The device according to p. 5, in which the change in the output signal of the limiting controller is achieved by adding the second output signal of the main controller with the setting of the limiting controller. 8. Устройство по п. 5, в котором изменение выходного сигнала ограничивающего регулятора достигается путем сложения второго выходного сигнала главного регулятора с выходным сигналом ограничивающего регулятора. 8. The device according to claim 5, in which the change in the output signal of the limiting controller is achieved by adding the second output signal of the main controller with the output signal of the limiting controller.
