In the boiler houses of thermal power plants there is a problem when applying modern automation methods to theoperation modes of two high-speed asynchronous electric motors. For heating of boiler rooms, gas or fuel oil is used,problems of automation of operating modes of fan units, interconnected with the amount of carbon monoxide,completely not burnt out fuel oil, are known. Given these circumstances, it is proposed to use modern technology andtechnology in the engine operating mode. In this article, advantages are shown in the application of numerical programcontrol in the automation of the operating modes of electric motors.

Key words: programmed numerical control, two high-speed asynchronous electric motors, gas volume, capacitivesensor, blower fan, boiler-house, starting current, asynchronous motors, alternating current motor, productivity, switch.
