| Abstract: | The feasibility of cancelling the local discriminating device for remote tripping protection is analyzed. The scheme that using the remote tripping function of the optic-fiber differential protection replacing remote tripping protection to realize incorporation of the two kinds of protection is proposed. The device and secondary circuit are simplified,which produces great economic benefit. This paper also analyses the shortcoming existing between the security and reliability of the 750 kV remote tripping protection and puts forward the solve method. Finally,the improving measure for the remote tripping function of the optic-fiber differential protection is presented. |
