风力发电机并网控制方法的研究

目前,风力发电系统都存在并网功率不大、风力发电机与并网控制逆变器不匹配、利用效率低等问题。针对这种情况,该文提出了一种不可控整流、升压电路、全桥逆变的综合电路的方案设计,详细阐述了其工作原理。该文针对提出的方案,设计出并网功率为3kW的逆变控制系统并对其参数选取进行详细的计算、仿真和实验。仿真及实验结果表明,系统运行可靠,其稳态性能和动态性能良好,从而验证了并网控制方案的可行性和系统理论分析的正确性。

Study on Grid-Connected Generator Control System of Wind Power

Currently,the wind power generation system have these problems：the power grid is not big,wind power generation and grid-connected inverter does not match and in low efficiency etc.This paper presents the case of a non-controlled rectifier,booster circuit,full-bridge inverter integrated circuit design,described in detail how it works. On the proposed scheme,the paper gives 3kW inverter control system and its parameters are detailed calculated,simulated and experimented.The simulation and experimental results show that the system is reli- able and in steady-state with good dynamic performance.Therefore,the results verify the feasibility and the correctness of analysis of system theory.
