HIEE220280R11 KU7461d Excitation Regulator features each unit
(1) analog input/output channel. Input sampling quantities include generator terminal voltage, stator current, active power, reactive power, rotor current and system voltage. The sampling can be AC or DC. Ac sampling should be done at 12 o ‘clock every week.
(2) switching input/output channel. For the sake of safety and interference prevention, the input and output channels of switching quantity should be isolated by photoelectric. It is mainly used for field operation, parameter setting, unit state, protection and other signals input, as well as the regulator to the field of other excitation equipment operation instructions and the regulator of various fault signals output.
(3) digital phase shift trigger. Its function and structure are similar to that of analog phase shift flip-flop, which consists of synchronous shaping, phase shift calculation, pulse formation and pulse amplification.
