A substation automation wide-area operation and maintenance interoperability test system and test method

Abstract

The invention discloses a substation automation wide-area operation and maintenance interoperability testing system and method. The substation automation wide-area operation and maintenance interoperability testing system comprises a wide-area operation and maintenance master station, a wide-area operation and maintenance sub-station and experimental equipment, and is characterized in that the wide-area operation and maintenance master station comprises a service management center and an operation and maintenance center, the wide-area operation and maintenance sub-station comprises a substation data communication gateway computer and a monitoring host, and the experimental equipment comprise a GPS consistency testing client tool, a regulation and control master station preposed simulation system, a GSP based message analysis and diagnosis tool and a protection measurement and control information simulation system. The system and method disclosed by the invention are used for carrying out an interoperability test on communication services between the wide-area operation and maintenance master station and the wide-area operation and maintenance sub-station of substation automation, checking the applicability of a general service protocol of an electric power system on various applications of substation automation equipment wide-area operation and maintenance, and achieving consistence in understanding of monitoring manufacturers for various applications of wide-area operation and maintenance before implementation of field applications.

Description

technical field [0001] The invention belongs to the technical field of power system automation, and in particular relates to a substation automation wide-area operation and maintenance interoperability test system and a test method. Background technique [0002] With the deepening of the "big operation" of regulation and control integration, the construction of substations has become an unattended mode. Substation has the characteristics of wide area and many maintenance points. The operation and maintenance mechanism based on on-site operation has become more and more difficult to meet the needs of the development of smart grid. For advanced problems, it is urgent to develop substation automation wide-area operation and maintenance applications to solve the interoperability problem between the main and sub-stations of wide-area operation and maintenance based on the power system communication service protocol (General Service Protocol, GSP) communication, and to achieve the...
