Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

When the centralized bypass control faces the fault of the power module, fault information is sent to the valve control system, the valve control system sends a bypass control command, when the downlink communication fault of the power module occurs, the power module can only control the bypass switch to be closed (such as an overvoltage bypass) through a hardware backup protection loop of the power module due to the fact that the power module can not receive the bypass control command, the reliability of the power module is reduced,
when the distributed bypass control is used for judging fault information and controlling the bypass of the power module when the power module fails, the valve control system still can send normal power module control commands because the valve control system can not receive the state information sent by the power module when the power module fails in uplink communication, and the power module control board does not detect the fault, so that the power module can be damaged finally.
