摘要：
Wind turbine generators (WTG) are urgently expected to provide the active power control (APC) to support the secondary frequency regulation instead of the maximum power point tracking (MPPT) control for maximizing generation benefit. By originating from the framework of MPPT control, the existing APC strategies for WTGs are developed usually from the steady-state viewpoint. WTG is attempted to be controlled to a stable equilibrium point where the power command dispatched from power systems can be followed by the electric power produced by WTG while the turbine stability is maintained. However, under turbulent wind, the wind rotor with large inertia spends most of the time in rotor speed regulation rather than operating at the stable equilibrium point, which consequently exerts a significant influence on the control performance of APC. Hence, in this paper, by summarizing the existing APC strategies of WTGs, two types of rotor speed variation mode, including active rotor speed variation and passive rotor speed variation, were proposed. They essentially differed in the mechanism and dynamic process of rotor speed variation. Through frequency-domain analysis and experimental study, these two types of rotor speed variation mode were compared from the response to power command, the drive train load and the fatigue load of pitch servo. The comparison results show that the passive rotor speed variation is more suitable for the turbulent wind scenario, because it abandons the attempt to track stable equilibrium points and utilizes the inertial response of wind rotor as an energy buffer against wind speed fluctuations. This work can provide a foundation for the design and optimization of APC strategies of WTGs from the perspective of operation mechanism of wind turbines. © 2022 Chin. Soc. for Elec. Eng.
