摘　　要：针对变速风电系统的控制需要,设计一种新型的无级增速式风电系统,提出系统无级增速的控制原理及其控制策略,构建系统主要环节的等效模型,并进行仿真实验研究,研究结果验证了系统无级增速控制的可行性与高效性。同时表明,相对于仅采用变桨距控制的风电系统,采用变桨距控制并兼具有无级增速控制的系统能更高效地稳定输出功率,并能更有效抑制转矩的波动。Aiming at control technology of variable speed wind power generation system, a new type of stepless increasing speed wind power system was designed. The control principle and strategy of the system were analyzed to construct the equivalent model of main parts of the system and carry out the simulation study. The research results verify the feasibility and efficiency for stepless increasing speed control of the system. Compared with the wind power generation system with variable pitch control, the system with variable pitch control and stepless increasing speed control at same time can stabilize the output power more efficiently, and can suppress the torque ripple more effectively.
