FIELD: heat power engineering.
SUBSTANCE: proposed electrohydraulic system can be used in production, reconstruction and operation of steam turbine control systems. According to proposed invention, system is furnished with regulating valves position control unit and proportional integral controller with corresponding couplings, and hydraulic servo motors installed directly on regulating valves. Proposed design provides external control characteristics, as to nonuniformity, insensitivity, complying with. Regulations and improves stability of control of turbine speed by eliminating hunting under any operating conditions of turbine.
EFFECT: provision of safety, reliability, higher degree of automatic and simplified conditions of operation of turboplants.
