Synthesis of an additional controller for stabilization of angular velocity of the steam turbine rotor

The article considers the problems of an additional regulator insertion into the rotor speed control loop in the steam power turbines, when the turbine generator works under an autonomous load. The results of the standard control system operation for the isolated power systems are presented. An additional controller ensures the mode in which the output coordinates the controlled object (turbine) track along a desired trajectory of their change. The desired stabilization trajectory is selected based on the safe turbine element operation. The algorithm of the additional controller synthesis is proposed, the linearization Newton-Kantorovich methods of an optimal control and the matrix operator tool are used. The algorithm of a regulator operation ensuring the mode of the object phase coordinates, which track the specified signal, is also proposed. The possibility of a real-time object control is considered. The reference signal type defining a desired stabilization trajectory is determined. The results of the joint operation of two regulators are presented.
