Correlation mapping and diagnosis method of virtual and real circuit in intelligent substation virtual and real diagnosis system

Abstract

The invention discloses a virtual and real loops association mapping and diagnosis method of a virtual and real diagnosis system of an intelligent substation, and the method comprises an association mapping method of a process layer virtual and real loops and a diagnosis method of the process layer virtual and real loops; the association mapping method of the process layer virtual and real loops comprises the following steps: 1, building a real loop model; 2, building an association relation between the real loop and a message block, namely defining a sending port and a receiving port, and a sent or received message block APPID; 3, building the association relation between the port and a virtual loop broken link warning signal, port power and port state warning signal; 4, storing the configured association relation in a secondary operation and maintenance model file; 5, parsing a SCD model and the secondary operation and maintenance model, and storing the model association relation ina library. The association relation of the real loop and the virtual link is built, and technical problems, such as failure in building of process layer virtual and real loops mapping and implementation of diagnosis of process layer virtual and real loops, of the virtual and real loops of the intelligent substation are solved.

Description

technical field [0001] The invention belongs to the intelligent substation control technology, in particular to a virtual-real circuit correlation mapping and diagnosis method of a virtual-real diagnosis system of a smart substation. Background technique [0002] With the popularization and construction of the smart grid, the equipment composition and technical characteristics of the smart substation have undergone major changes at present. The secondary system is more complex, and it is difficult to locate the defect, and it is difficult for the inspection personnel to grasp it. Accurate fault location for virtual and real circuit faults has broad application value for improving the operation and maintenance level of smart substations. [0003] At this stage, some achievements have been made in the diagnosis and research of virtual and real circuits in the process layer of smart substations. But most of the current research results are based on the standard substation conf...
