Design and application of short circuit test scheme for Hu Zhou DPFC project

The short circuit test of distributed power flow controller (DPFC) is still a blank in the world. In order to test the effectiveness and adaptability of DPFC in case of line failure, it is necessary to carry out short circuit tests in DPFC projects. Based on the Hu Zhou DPFC Project, this paper proposes the control and protect strategy of DPFC which is coordinated with the protect strategy of AC line, designs single phase short circuit grounding test scheme of the AC line where DPFC is located. In the application, the action logic of DPFC under single-phase grounding fault is verified, the single phase short circuit test of DPFC were completed for the first time, and the transient voltage and current were obtained. It provides technical support for the popularization and application of DPFC project.
