Abstract

The invention discloses a method for realizing seamless communication between a master scheduling station and a substation of a power grid. The method comprises: a model configuration step of establishing an international electrotechnical commission (IEC)-61850-standard-format-based whole-station unified configuration model file comprising a primary equipment model and a second equipment model in the substation; a secure file transfer protocol (sFTP) file transmission step of uploading data comprising the whole-station unified configuration model file to the master scheduling station through sFTP connection by using a telecontrol workstation in the substation; a model conversion step of converting the whole-station unified configuration model file into an IEC-61970-standard-format-based common information model comprising communication information; and a seamless communication step of establishing seamless communication connection between the master scheduling station and the substation. The invention also discloses a corresponding system for realizing the seamless communication between the master scheduling station and substation of the power grid. By the method and the system, the seamless communication between the digital substation and the master scheduling station can be realized under the condition of avoiding influence on the conventional substation and the master scheduling station as much as possible.

Description

technical field [0001] The invention relates to the field of electric power system automation, in particular to a method and system for realizing seamless communication between a grid dispatching master station and an intelligent substation. Background technique [0002] In the current power grid automation system, the application of the digital substation based on the IEC 61850 standard and the dispatching master station based on the IEC 61970 standard has been mature. However, the models and service interfaces of IEC 61850 and IEC 61970 are quite different, and the two are heterogeneous systems. Therefore, in existing applications, it is necessary to configure models, draw wiring diagrams, and configure communication point tables in substations and dispatching master stations respectively. On the one hand, it is impossible to share models and graphics, and give full play to the technical superiority of IEC 61850 and IEC 61970 ; On the other hand, maintaining the consisten...
