摘要：

Now active power modulation is major approach to suppress low frequency oscillation of power systems linked with VSC-HVDC. In order not to affect VSC-HVDC's active power transmission capacity and make full use of converter's modulation ability, in this paper, a damping controller design method is proposedusing both rectifier and inverter's reactive power to suppress low frequency oscillation based on oscillation energy decrease theory. Reactive power control regularities are deduced. According to the control regularities,a bilateral reactive power damping controller using fuzzy logical method is obtained. It is no need to identify system mode in controller design, so thedesigned controller is independent ofaccurate mode of system's specific operating condition with strong robustness. To validate performance of the designed controller, a traditional pole assigned controller is designed for contrast. Simulation results show that bilateral fuzzy logic reactive power damping controller designed in this paper can suppress low frequency oscillation efficiently and has strong robustness. Besides, the damping controller don't need special parameter coordination measures to achieve two coordinated outputs of the controller, and can make full use of two converter's modulation capacity. © 2016, Power System Technology Press.
