Excitation regulator which can be remotely monitored and method

The invention discloses an excitation regulator which can be remotely monitored and a method. The excitation regulator comprises an excitation control unit and a generator terminal voltage measuring module, a system voltage measuring module, a generator terminal current measuring module and an information receiving-sending unit which are connected with the excitation control unit. The generator terminal voltage measuring module obtains the voltage of a generator terminal and sending the voltage to the excitation control unit. The system voltage measuring module obtains the voltage of a system and sends the voltage to the excitation control unit. The generator terminal current measuring module obtains generator terminal current of a generator and sends the current to the excitation control unit. The generator terminal current measuring module obtains generator terminal current and sends the current to the excitation control unit. The excitation control unit judges whether the generator works normally or not ac
