SYSTEM TO MONITOR AUTOMATIC CONTROLLERS OF EXCITATION AND SYSTEM OF EXCITATION OF POWER PLANT GENERATORS Russian patent published in 2014 - IPC G05B23/00 G01R31/02 

FIELD: power engineering.

SUBSTANCE: system is proposed to monitor automatic controllers of excitation and systems of excitation of power plant generators, comprising a group of meters, information inputs of which are connected to outputs of appropriate generators, and a group of converters of measurement information, at the same time a unit of synchronisation is introduced, the output of which is connected to synchronising inputs of group metres, the outputs of which are connected to inputs of appropriate converters of measurement information, and also a unit of control of operation of automatic excitation controllers (AEC) in operation modes, a unit of AEC operation control in emergency modes and a unit of AEC operation control in special modes, inputs of which are connected to outputs of converters of measurement information of the group, and a unit of generation of monitoring result, inputs of which are connected with outputs of the unit of AEC operation control in operation modes, a unit of AEC operation control in emergency modes and a unit of AEC operation control in special modes, corresponding to the mode of limitation of minimum excitation and/or mode of limitation of the double value of rotor current.

EFFECT: expansion of functional capabilities of a system of monitoring of automatic excitation controllers due to provision of monitoring in operation, emergency and special modes of operation of power systems.
