Service response method and service system for accessing intelligent substation to control master station

Abstract

The present invention relates to a service response method and a service system for accessing an intelligent substation to a control master station. The method comprises the steps that a client of a service consumption end requests a service from an output agent; the output agent inquires a domain management center of the service consumption end and sends a service request to an input agent of a service provider end according to positioning information after receiving returned positioning information; the input agent sends a request to position the service to a service management center of the service provider end, and sends the service request to the service provider after receiving returned service provider information; and the input agent receives response information of the service provider, and then forwards the response information to the output agent of the service consumption end, and the output agent of the service consumption end forwards the service response information to the client of the service consumption end. Through adoption of the service response method and service system, the communication framework between the intelligent substation and the master station is expanded, and a more flexible communication manner is provided to meet the increasing interaction business demands between the master station and the substation.

Description

technical field [0001] The invention belongs to the field of electric power system automation, and in particular relates to a service response method and a service system for connecting an intelligent substation to a control master station. Background technique [0002] Smart substations and control master stations are the basis of modern large power grid monitoring, and are the key to monitoring the operating status of the power grid and maintaining the safe and stable operation of the power grid. The real-time data interaction between the substation and the control master station usually adopts communication protocols such as IEC 60870-5-101 or IEC 60870-5-104, DL / T 476, which can effectively solve the "four remote" data transmission, but in the "control Under the background of "integration", the high-level business interaction support between the control center and the substation is insufficient, and the establishment of a service system architecture oriented to the integ...

AI Technical Summary

Problems solved by technology

With the continuous strengthening of the functions of smart equipment in smart substations, the lack of means of interaction between smart substations and control master stations has become more and more obvious. The technical level of substation access to control centers and integrated operation management of control centers needs to be improved.
