The paper analyses an operation of the typical three-impulse automatic control system (ACS) of the steam generator water supply. A mathematical model has been developed to test its operability for load shedding, allowing you to set maximum deviations of the water level without full-scale tests, without adjusting the operation settings technological protections by the level of water in the drum. Reasons identified static regulation errors when working out internal and external disturbances in the flow rate of superheated steam in a typical ACS. The relevance of modernization of a typical ACS power supply to the steam generator water. Altogether, under all influences, a significant improvement in the quality of regulation was obtained compared to a typical three-impulse automatic power control system. The relevance of modernization of a typical system of automatic control of water supply of a steam generator to eliminate static regulation errors in a wide range of changes loads.
