@@@@In order to fast clear faults and avoid over-stage trip in the Metro power supply mode,this article proposes one near zone quick scheme based on the optical fiber differential protection and overcurrent protection.This scheme protects the element exchange message such as "near token" information by wire and fibers,while accurate fault location is rapidly isolated and the health region power resupply is ensured.
