DSPACE-based distributed power flow controller series side closed-loop simulation test method

Abstract

The invention provides a distributed power flow controller series side closed-loop simulation test method based on dSPACE. According to the method, a control system on a series side of a DPFC is constructed in dSPACE to serve as a physical controller, and then is subjected to interface and resource configuration through related software matched with the dSPACE, then ADPSS and the dSPACE are connected through a shielded wire, and a closed-loop simulation test is carried out, so that a new method is provided for research and development of a power electronic device control system in future. Themethod has the advantages that the calculation processing of SPWM is carried out in FPGA, so that the simulation precision is high, and the real-time simulation can be carried out at the same time; acarrier generation module is also constructed in the FPGA, so that the frequency range of the carrier generation module can range from 0 MHz to dozens of MHz; and the dSPACE serves as a physical controller, so that control parameters can be modified in real time, the test time is greatly shortened, the product research and development period is greatly shortened, and waste of materials is reduced.

Description

technical field [0001] The invention belongs to the technical field of flexible alternating current transmission. It specifically involves the closed-loop simulation test method of the series side of the distributed power flow controller based on dSPACE. Background technique [0002] The distributed power flow controller is a new type of flexible AC power transmission device, which is evolved from the unified power flow controller (Unified Power Flow Controller, UPFC). However, the series side of the distributed power flow controller adopts DSSC technology, which is distributed and arranged on the transmission line or power tower, which is more economical, has higher redundancy and stronger reliability. Domestic research on distributed power flow controllers is still in the stage of digital off-line simulation verification, and real-time simulation of distributed power flow controllers has not yet been realized. Hardware-in-the-loop simulation HILS (Hardware-in-the-loop si...
