基于变电站继电保护装置定值远方操作方法
摘要：
本发明公开一种基于变电站继电保护装置定值远方操作方法，包括建立安全授权体系步骤；远程定值操作修改步骤；远程定值区切换步骤；远程软压板投退执行步骤；远方复归信号步骤；其中，建立安全授权体系步骤具体包括制定安全密匙体系、操作票的加密及下发、操作票启动执行。本发明所述的基于变电站继电保护装置定值远方操作的方法具有操作合法性检测和在线定值管理等特点。
摘要（英）：

The invention discloses a constant value remote operation method based on a transformer substation relay protection device. The method comprises a security authorization system establishment step; a remote constant value operation modification step; a remote constant value section switching step; a remote soft strap switching on/off performing step; and a remote signal resetting step. The security authorization system establishment step concretely includes security key system formulation, operation order encryption and issuing and operation order start performing. The constant value remote operation method based on the transformer substation relay protection device has the characteristics of operation legality detection and online constant value management.
