Abstract

This paper first analyzes the topology, parameter design and control strategy of the distributed DC chopper and improves its control strategy by proposing a calculation method for the number of input submodules. Based on the actual parameters of the Rudong offshore wind power flexible project, a system model was established in PSCAD/EMTDC. By comparing response curves of distributed DC chopper with existing control strategy and improved control strategy, it is shown that distributed DC chopper with improved control has a smooth energy consumption curve, the energy consumption power can be fully balanced with the actual power difference of the system, and the fault ride-through performance is more superior.
