Abstract

This article first briefly introduces the control principle of flexible DC transmission, and focuses on the analysis of the dual-loop vector control used in the simulation model of this article. Then, based on the existing knowledge, the simulation model was built in two cases: namely, the DC output after the multi-machine AC integration and the single-machine DC output. In the first model, an ideal AC voltage source is used to simulate the AC power generated by the wind farm after the collection, and then the rectifier part is connected, and then the DC-DC boost is directly performed, and finally the load is connected to the DC high-voltage output side. The output power can be controlled by the load; in the second model, a permanent magnet synchronous motor is used to simulate the output of AC power instead of the fan. After that, the rectifier part is connected to the first model, and then the DC-DC boost is directly performed, and finally the output side is directly connected Ideal DC power supply. The ideal DC power supply here is equivalent to an infinite ideal DC power grid.
