Abstract

本公开提供一种驱动系统、盘车系统和风力发电机组，驱动系统包括：变流器柜，包括第一变流器和第二变流器，第一变流器和第二变流器均包括经直流母线相连接的机侧变流器和网侧变流器；网侧电路，连接在第一变流器的网侧变流器和风力发电机组的并网点之间；盘车电路，将第一变流器的网侧变流器和机侧变流器彼此远离的一端相连接；第一母线电路和第二母线电路，分别连接在第一变流器与第二变流器的正直流母线之间、第一变流器与第二变流器的负直流母线之间，其中，驱动系统具有盘车模式和并网模式，在盘车模式下，网侧电路断开，盘车电路、第一母线电路和第二母线电路导通，在并网模式下与之相反。本公开显著降低了额外工装费用，并可控制整机成本。
