Features
GDx series excitation controller can realize full-automatic excitation control and unattended operation after one key start!
Gdx-d1 intelligent excitation controller is a special product for brushless excitation generator with generator terminal voltage of 400V. Users can freely modify excitation operation parameters. It is one of the most advanced excitation controllers at present.
◆ automatically track the grid voltage after the generator is connected to the grid;
◆ after grid connection, operate according to the set power factor value to realize constant power factor;
◆ after tripping, the voltage will automatically return to the set value to prevent overvoltage;
◆ automatically identify the shutdown process and conduct de excitation control;
◆ when "single machine operation" is running, it automatically operates according to the set voltage, which can keep the generator voltage constant;
◆ parameters can be set especially for units with unstable excitation operation;
◆ automatically reduce excitation (reactive power) in case of generator overcurrent (over generation) to prevent generator overcurrent;
◆ set value password protection to prevent parameters from being modified by irrelevant personnel;
◆ equipped with upper computer communication interface to realize computer control (optional).
technical parameter
▲ applicable to brushless excitation synchronous generator with generator terminal voltage of 400V.
▲ GDx － D1 excitation controller is applicable to: excitation voltage 0 ～ 80V and excitation current 0 ～ 18a
◆ Input signal:
Current: rated current 5A, connected through current transformer
Voltage: generator voltage 400V, grid line voltage 400V
Grid connection identification: auxiliary normally open contact of grid connection circuit breaker
