The\r\ndrawbacks of manual Q-V control are briefly listed, and the design\r\nrequirements for coordinated Q-V controller are specified.\r\nTheoretical background and mathematical model of the new\r\ncontroller are presented next followed by validation of developed\r\nMatlab\/Simulink model through comparison with recorded\r\nresponses in real steam power plant and description of practical\r\nrealisation of the controller. Finally, the performance of\r\ncommissioned controller is illustrated on several examples of\r\ncoordinated Q-V control in real steam power plant and compared\r\nwith manual control.","references":"[1] J.
