The control module 140 is electrically connected to the first excitation channel 110, the second excitation channel 120, and the third excitation channel 130. For example, the control module 140 may be a central processing unit (CPU, center processor unit). Wherein the first excitation channel 110, the second excitation channel 120, and the third excitation channel 130 are independent of each other. For example, the first excitation path 110 and the second excitation path 120 may be in a manual mode, and the third excitation path 130 may be in an automatic mode.
In one embodiment, the first excitation channel 110 generates first trip drive information when at least one fault event is detected. For example, the first trip driving information is relatively generated when at least one element portion of the first excitation channel 110 is in a fault event. The second excitation channel 120 generates second gate drive information when at least one fault event is detected. For example, the second trip driving information is relatively generated when at least one element portion of the second magnetic path 120 is in a fault event. Wherein the third magnetic path 130 generates third trip driving information when a fault event is detected. For example, the third trip driving information is relatively generated when at least one element portion of the third magnetic path 130 is in a fault event.
After the control module 140 receives the first trip driving information transmitted by the first excitation channel 110, the second trip driving information transmitted by the second excitation channel 120, and the third trip driving information transmitted by the third excitation channel 130, the control module 140 relatively generates trip information according to the first trip driving information, the second trip driving information, and the third trip driving information, and then the control module 140 transmits the trip information to the first excitation channel 110 and the second excitation channel 120, and simultaneously disables the first excitation channel 110 and the second excitation channel 120 by the trip information. In other words, the control module 140 includes hardware and software to implement that when at least one fault event occurs in the first excitation channel 110, at least one fault event occurs in the second excitation channel 120, and at least one fault event occurs in the element portion of the third excitation channel 130, the trip information sent by the control module 140 immediately closes the first excitation channel 110 and the second excitation channel 120, so as to effectively protect the excitation system 100 from equipment damage. For example, the excitation system 100 may implement an automatic trip function through a programmable logic control circuit (PLC, programmable logic controller).

In yet another embodiment, after the control module 240 receives the first trip driving information transmitted by the first excitation channel 210, the second trip driving information transmitted by the second excitation channel 220, and the third trip driving information transmitted by the third excitation channel 230, the control module 240 relatively generates the trip information according to the first trip driving information, the second trip driving information, and the third trip driving information, and then the control module 240 transmits the trip information to the first relay 217 of the first excitation channel 210 and the second relay 227 of the second excitation channel 220, and the control module 240 disables the first excitation channel 210 and the second excitation channel 220 through the trip information. In other words, after receiving the first trip driving information, the second trip driving information and the third trip driving information, the control module 240 generates the trip signal to close the first excitation channel 210 and the second excitation channel 220, so as to effectively prevent the first excitation channel 210 and the second excitation channel 220 from being damaged.
