Direct interconnection is a novel technique for interconnecting offshore airborne wind energy (AWE) generators which facilitates the removal of power converters from the offshore generation site. In this technique, unlike the conventional approach, all generators are interconnected directly and after dispatching the generated power to shore, a back to back converter or several paralleled back to back converters change the generated power to grid-compliant power. Considering that the high expenses of offshore operations for back to back converter repair and maintenance and the higher accessibility of shore-side back to back converters, this technique can improve the reliability and economy of the energy generation system. This research aims to implement and study the practicality and reliability of the direct interconnection approach for offshore non-reversing pumping mode airborne wind energy generator systems. The interaction of direct interconnected AWEs in normal and fault conditions is investigated, and synchronisation, frequency control and load sharing control of the AWE farm are examined and discussed.

正常和故障条件下海上机载风能系统直接互联技术分析

直接互连是一种用于互连海上机载风能 (AWE) 发电机的新技术，它有助于从海上发电站拆除电力转换器。在这种技术中，与传统方法不同，所有发电机直接互连，在将产生的电力分配到岸上后，背对背转换器或几个并联的背对背转换器将产生的电力更改为符合电网要求的电力。考虑到海上作业背靠背变流器维修维护费用高，岸侧背靠背变流器可达性较高，该技术可以提高发电系统的可靠性和经济性。本研究旨在实施和研究海上非反向泵送模式机载风力发电机系统直接互连方法的实用性和可靠性。研究了正常和故障条件下直接互连的 AWE 的相互作用，并检查和讨论了 AWE 群的同步、频率控制和负载分配控制。
