摘要：
When the direct-drive permanent magnet synchronous generator (D-PMSG) is located near the line-commutated-converter based high voltage direct current (LCC-HVDC) rectifier station, the sub-synchronous oscillation (SSO) characteristics of the system are still unclear, and relevant research needs to be carried out. In response to above the problems, this paper used the modular modeling method to establish a small signal model of the D-PMSG integrated with LCC-HVDC system, and the participation of D-PMSG and LCC-HVDC in the system SSO mode was studied with eigenvalues and participation factors. The eigenvalues were used to analyze the influence of system parameters on SSO damping. Research results showed that there was an SSO mode in which D-PMSG and LCC-HVDC participated together, and the LCC-HVDC connection provided negative damping for the system SSO. When the D-PMSG transmission line impedance and the integral coefficient of the outer loop of the GSC controller increased, the damping of the SSO mode decreased. When the proportional coefficient of D-PMSG GSC controller outer loop and D-PMSG DC side capacitance and wind speed of D-PMSG and LCC-HVDC constant current controller increased, SSO mode damping increased. Based on the PSCAD/EMTDC time domain simulation results, the correctness of the theoretical analysis was verified. © 2022 Chin. Soc. for Elec. Eng.
