Research and Development of Active Ground Protection Device for DC System

摘要：

　　The concept and harm of ground fault in DC system is discussed, and the weakness of existing method for ground fault is analyzed which only can alarm when ground fault happens, so they cant solve the harm brought by ground fault fundamentally.Active ground protection with fault isolation function based on power electronic technology is proposed, its topological structure and principle of protection implementation is introduced.And the performance and advantages of the protection device is discussed.The hardware and software of the protection device is designed and the protection prototype is made and tested.
