基于双同步坐标的无刷双馈轴带发电控制系统

航运业的碳氮排放在全球排放中占较大比例,充分利用推进主机的剩余动力进行轴带发电,既可以减少碳氮的排放,又有助于提高燃料的利用效率。无刷双馈轴带发电系统摆脱了同步发电机型轴发的全功率变换器要求和有刷双馈型轴发维护要求高、安全性差的缺点。本文在dq0模型的基础上,通过双同步模型建立了针对功率绕组的磁场定向矢量控制方法,并设计了独立和并网发电两种运行模式下的控制策略。通过仿真和物理实验证明了建模方法和控制策略的有效性和可行性。

Brushless Doubly-Fed Ship Shaft Generation Control SystemBased On Dual Synchronous Coordinates

The emission of shipping industry accounts for a high proportion in global effluent of carbon and nitrogen. It is feasible to restrain the carbon dioxide as well as increase the energy utilization efficiency by making full use of surplus power of pushing engine. The shaft generation system based on brushless doubly-fed generator, which discards the full-rated converter of synchronous generator and overcomes the flaws of rigorous maintenance along with low safety of conventional doubly-fed generator, could lead a new trend in corresponding field. Based on the rotor speed model, dual-synchronous model has been inferred and the power winding field-oriented vector control method has been established. This paper proposes two operation modes including independent and grid-connected generation based on brushless doubly-fed generator. And the proposed strategy has been proved effectiveness and feasibility in modeling by simulation and physical experiment.
