PROTECTION AND CONTROL SYSTEM FOR INTELLIGENT SUBSTATION AND SOFTWARE- DEFINED REALIZATION METHOD BASED ON PROTECTION AND CONTROL SYSTEM FOR INTELLIGENT SUBSTATION

摘要

The application relates to a protection and control system and a software-defined realization method based on the protection and control system. According to the application, an intelligent substation adopts a centralized modeling manner of directly adding and updating all of a protection, a measurement and control, an exchange and a telecontrol functions in substation configuration descriptions by taking the whole substation as a modeling object, instead of a decentralized modeling manner of sequentially adding a single physical apparatus and then adding functions of each apparatus adopted by a traditional substation. Since SCD files of the intelligent substation are created based on merging unit and intelligent terminal integrated devices and special functions planned by the intelligent substation, configuration information of each of the special functions is set in the SCD files of the intelligent substation (101), an aim of defining the special functions of the intelligent substation through software is achieved.
