Abstract:

On the basis of the status quo of the locally installed protection,the scheme of locally installed protection is proposed.The characteristics of singlemaster scheme and fullmaster scheme are compared for crossinterval protection. It focuses on singlemaster scheme of transformer protection and the fullmaster scheme of busbar protection.The key technical issues of locally installed protection are pointed out.Current progress of research and development of localized protection devices is summarized and the application scenarios for locally installed protection is prospected.
