Research of the dynamics of the electrohydraulic speed control circuit of a low-power steam turbine rotor, built on the basis of a modern local high-precision high-speed electromechanical drive (EMD). The practical interest in this concern is caused by the fact that main part of the steam turbines of the Kaluga Turbine Plant have now switched to a complete set with an electrohydraulic control system, which have a number of operational advantages compared to the previous hydrodynamic system [8]. The high performance characteristics of such systems are due to the use of EMD based on a roller-screw pair in their design, the main authentic features of which are taken into account in the authentic mathematical model.
The model is based on traditional ideas about the dynamics of such systems, taking into account a number of essentially nonlinear elements.
Keywords:riding cut-off valve, roller screw drive, electromechanical transducer, steam turbine control system, electrohydraulic actuator.
