AN INFLUENCE OF DISSOLVED AIR CONTAIN IN WORKING OIL OF A GOVERNING SYSTEM TURBINE DRIVE ON CHARACTERISTIC
The paper investigates the influence of the volume of dissolved air in the working oil of a steam turbine control system on the dynamic stability of its operation. The study is conducted on a linearized mathematical model of a turbine, taking into account its dynamics, as applied to two specific types of turbines of KTZ OJSC, which have been widely used in power engineering since the 70s. For them, the calculated maximum permissible volumetric air content in the working fluid of the control system is determined with so on. loss of its stability, as well as general formulas for a similar assessment on other types of turbines of a similar design.
