In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Fig. 2, be the phase-shifting control method flow diagram of multiple convertor system provided in an embodiment of the present invention,
The phase-shifting control method can be applied to multiple convertor system as shown in Figure 1.Above-mentioned multiple convertor system includes m unsteady flow
Device group Ai, wherein i ∈ [1,2,3 ..., m], m are the integer greater than 1, and each current transformer group AiIncluding a main control unit B1
It is a from control unit B with n-1j, wherein j ∈ [2,3 ..., n], n are the integer greater than 1.Above-mentioned main control unit B1With from control
Unit BjIt is made of respectively converter cell (such as four quadrant convertor unit), and phase shift can be carried out according to the phase shifting angle of setting
Transformation.
Specifically, in i-th of current transformer group, main control unit B1Phase shifting angle be αiB1, from control unit BjPhase shift

Other current transformers in multiple convertor system, it (includes normal mark i.e. in status information that above-mentioned status information, which is divided into normal condition,
Know) and malfunction (including failure identification i.e. in status information).Certainly, to reduce the communication data between current transformer group,
Current transformer group can be made only to send fault message in failure, and do not send data when current transformer group operates normally.
Step S22: number of the current transformer group of any non-faulting in the current transformer group for receiving fault message and breaking down
When amount is less than preset value, main control unit is adjusted according to preset function and from the phase shifting angle of control unit.And it is breaking down

Report an error shutdown when preset value.All adjustment are completed in a grid cycle.
Also, m-1 non-faulting current transformer group is in the failure for receiving k-th of (k ∈ [1,2,3 ..., m]) current transformer group
When information, each non-faulting current transformer group based on the received failure current transformer group IP address judge itself number and failure unsteady flow
The size relation of the number k of device group, and main control unit phase shifting angle is adjusted according to following calculating formula (3), while the value of m being made to subtract 1:
Wherein, αiB1For the phase shifting angle of the main control unit in i-th of current transformer group (non-faulting current transformer) before adjustment,
βiB1For the phase shifting angle of the main control unit in i-th of current transformer group (non-faulting current transformer) after the adjustment.
Correspondingly, each non-faulting current transformer group can adjust the n-1 phase shifts from control unit according to following calculating formula (4)
Angle:
Wherein, the βiBjFor j-th in i-th of current transformer group (non-faulting current transformer) from control unit after the adjustment
Phase shifting angle.
It, can root when current transformer group receives multiple failure messages (and the total quantity of failure current transformer group is less than preset value)
According to the number for the current transformer group for sending failure message, first according to preceding number (such as number 1 is before number 2) to main control
Unit and phase shifting angle from control unit are once adjusted, then further according to posterior number to main control unit and from control
The phase shifting angle of unit is adjusted again, and adjustment is completed in a grid cycle.
As shown in figure 3, being each unsteady flow in the phase-shifting control method of multiple convertor system provided in an embodiment of the present invention
The flow diagram of device group operation.Above-mentioned current transformer group specifically can execute following steps by master controller:
Step S30: judge whether current current transformer group operation is normal, and execute step in current current transformer group normal operation
Rapid S33 and step S34, it is no to then follow the steps S31.
Step S31: keep current current transformer group out of service.
Step S32: other current transformer groups into multiple convertor system send failure message.Above-mentioned failure message includes
The IP address and failure identification of current current transformer group.
Step S33: other current transformer groups into multiple convertor system send normal messages.Above-mentioned normal messages include
The IP address of current current transformer group and normal mark.
Step S34: the status message that other current transformer groups in multiple convertor system are sent, above-mentioned status message are received
That is failure message and normal messages.
Step S35: judge whether to receive the failure message that other current transformer groups in multiple convertor system are sent, i.e.,
It whether include failure message in received status message.If receiving failure message thens follow the steps S37, no to then follow the steps
S36。
Step S36: phase shifting control is carried out according to default phase shifting angle.
Step S37: judging whether the quantity of failure current transformer group in multiple convertor system is greater than or equal to preset value, and
Step S39 is executed when quantity is greater than or equal to preset value, it is no to then follow the steps S38.
Step S38: according to preset function, calculating formula (3) as escribed above, (4), dynamic adjust main control unit and from controls
The phase shifting angle of unit processed.
Step S39: out of service and report an error.
