Block appearance in REPEAT VISION#
Automatic excitation control (AEC) is a device that acts on the excitation system of synchronous machines to maintain the voltage in the electrical network at a given level.
To control slow-acting excitation systems (electric and high-frequency), control panels of the ЭПА-305, ЭПА-325Б, ЭПА-500 (EPA-305, EPA-325B, EPA-500) etc. type are used. These panels implement a proportional law for controlling the generator voltage and provide compounding according to the stator current, Fig. 1:[1]
