摘要

本文研究了用于光伏(PV)和风力电网的单相混合滤波发电机的正弦脉宽调制(SPWM)的实现。利用策略迭代算法,设计了一种改进的变步长扰动观测算法,并使用硬件描述语言(VHDL)熟练地实现了该算法。随后,新产生的并网电源在农村家庭的断供或限供期间补充现有的电网电力。该软件用于生成SPWM调制与太阳能和风能电网系统集成,该系统在Spartan 3 FPGA上实现。采用商用光伏阵列和HPW (Height Weight proportion,高度权重比例)的实验结果表明,该算法在稳定运行时的跟踪速度和抑制输出功率波动方面与传统控制器相当。仿真结果验证了该算法的有效性。

Implementation of FPGA Based Hybrid Power Generator for PV and Wind Grid Applications
This paper deals with implementation of Sinusoidal Pulse-Width-Modulation (SPWM) for a single-phase hybrid power filter generator for Photovoltaic (PV) and wind grid applications. Using policy iteration algorithm, an improved variable step-size perturbation and observation algorithm is contrived and it is implemented proficiently using a hard-ware description language (VHDL) (Very High Speed Integrated Circuit Hardware Description Language). Subsequently, the new generated grid source supplements the existing grid power in rural houses during its cut off or restricted supply period. The software is used for generating SPWM modulation integrated with a solar-power & wind power grid system which is implemented on the Spartan 3 FPGA. The proposed algorithm performs as a conventional controller in terms of tracking speed and mitigating fluctuation output power in steady state operation which is shown in the experimental results with a commercial PV array and HPW (Height Weight Proportional) show. Simulation results demonstrate the validity with load of the proposed algorithm.
