为了实现多逆变器并联风电系统信息交互和同步控制，提出了基于CAN总线的多逆变器并联风电并网系统控制方法。建立了共直流母线并联型拓扑的等效平均模型，利用CAN总线控制各逆变器正弦参考电压的幅值以均分并网功率。采用TMS320F28335实现全数字化并联风电系统设计，并基于55kW永磁风电样机对所提方法进行性能验证。实验表明，CAN总线同步驱动方法保证了多逆变器并联系统的数据交互性和同步性。

Multiple Parallel Inverter System Average Current Method Based on CAN Bus

Multi inverter parallel information exchange and synchronization controlling of wind power generation system is proposed based on CAN bus in inverter parallel system control method for wind power grid integration. Established a common DC bus for parallel topology equivalent average model, using the CAN bus control inverter Equalization of amplitude of the sine voltage reference to grid power. TMS320F28335 is used to realize full-digitalized parallel wind power system design, 55kW permanent magnet wind turbine prototype based on the method performance validation. Experiments show that synchronization CAN bus driven approach ensures that the inverter parallel system of data exchange and synchronization.
