Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0021] method embodiment
[0022] In this embodiment, STATCOM is a three-phase star topology, and the sub-module is an H-bridge topology, such as figure 1 shown. But, STATCOM among the present invention is not limited to these two topological structures, can be other topologies (such as single-phase) etc. that comprise cascade structure, and submodule is not limited to H bridge topology, and its submodule also can adopt H full Other topologies other than bridges (such as half-bridge, full-bridge), etc.
[0023] Such as figure 2 As shown, the cascaded STATCOM sub-module hybrid voltage equalization control method provided by the present invention can realize the balanced control of the sub-module voltage in the chain. The basic control strategy includes: average DC voltage closed-loop control, positive and negative sequence separation current closed-loop de...
