Decrease in Risk of Incident in Work Automatic Control System of the Gas-Pumping Unit

Is investigated statistics of refusals of the rotors speed measurement unit of a gas turbine unit (GTU). The major factors leading to critical decrease in reliability of measurement are found. Mathematical dependences for assessment of noise immunity of rotors speed measurement system are found. Criteria of increase in noise immunity of system of measurement are revealed. Effective methods of increase in reliability of measurement are found. The method of calculation of parameters of components of the low pass filter for measurement process optimization is offered. The comparative research of two methods of measurement of rotors speed is conducted: a method with use of the induction sensor and a method with use of the sensor on the basis of Hall's effect. Advantages of the second method of measurement are revealed.
