直驱式永磁风力发电机综合保护算法的研究

摘要

Tis paper analyzed the direct-drive permanent magnet wind generator protection involved the over-voltage protection, over-current protection, unbalance protection, over temperature protection and insulation protection, and put forward fve aspects of the basic protection algorithm.It also focuses on the study how these aspects of the basic protection algorithm combination with each other, making the formation of direct-drive permanent magnet wind turbine can be more efective protection of comprehensive protection algorithm.%本文分析了对直驱式永磁风力发电机进行保护所涉及到的过压保护、过流保护、不平衡度保护、过温保护和绝缘保护，并提出了这五个方面的基本保护算法。着重研究了如何将这五个方面的基本保护算法相互配合起来使用，使之形成能够对直驱式永磁风力发电机进行更有效保护的综合保护算法。
