Embodiment Construction
[0045] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0046] The invention provides a protection method for bridge arm short-circuit fault of a modular multilevel converter, the flow chart of which is as follows Figure 5 As shown, the method includes the following steps:
[0047]Step 1: Set the fault detection time interval Δt of the parallel protection switch of the bridge arm of the modular multilevel converter:
[0048] The modular multilevel converter is composed of three phases, and each phase is composed of upper and lower bridge arms connected in series with the same structure; the midpoint of the upper and lower bridge arms is connected to the AC end of the modular multilevel converter;
[0049] An example of its modular multilevel converter is figure 1 , each of the upper and lower bridge arms includes a reactor and N submodules 1 and 2 with the same structure; ...
