Problems solved by technology

In the existing technology, the distributed FA either lacks the configuration of the topological relationship, or the configuration of the topological relationship can only meet its own needs, and cannot form a model with the main power distribution station or between the power distribution terminal and the power distribution terminal. Mutual matching and mutual verification

Embodiment Construction

[0028] Figure 1~3 It is the best embodiment of the present invention, below in conjunction with attached Figure 1~3 The present invention will be further described.

[0029] The topology configuration method of distribution lines includes the following three parts: 1. Representation of feeder topology relationship; 2. Representation of topology relationship inside station; 3. Representation of corresponding relationship between station equipment and STU.

[0030] The representation of the feeder topological relationship is used to describe the connection relationship between the equipment on the feeder, including the feeder and the station equipment connected to the feeder. Station equipment can be pole-mounted switches, ring network cabinets, switching stations, distribution transformers, etc. When describing the topological relationship of the feeder, the station equipment connected to the corresponding feeder section is regarded as a whole, as a multi-port component.

Abstract

The invention relates to a topology configuration method of a distribution circuit, belonging to the field of electric power automation. The method is characterized by comprising the following steps: describing the following relationships by configuration language according to configuration rules: feeder topology relationship description used for describing a connection relationship of devices on a feeder, substation inner topology relationship description used for describing connection details in a substation, and description of the corresponding relation between substation equipment and smart terminal units (STUs). According to the method, the feeder topology relationship, the substation inner topology relationship and the corresponding relation between substation equipment and the STUs are described by the IEC 61850 standard, so that a technical support is provided for a power grid fault diagnosis technology and a self-healing technology in the prior art; therefore, the method can provide topological information without depending on the distributed intelligent feeder automation (FA) of a distribution automation master station, so that effective self-government among the STUs can be conveniently realized.

Description

technical field [0001] The invention relates to a topology configuration method of distribution lines, which belongs to the field of electric power automation. Background technique [0002] The feeder automation (FA) function is an important function of distribution network automation. It uses automation devices or systems to monitor the operation status of distribution lines, detect line faults in time, diagnose faulty areas and isolate faulty areas, and restore normal operation to non-faulty areas. powered by. Feeder automation can exist as an independent system, or as an advanced application software on top of the distribution automation master station system data acquisition and monitoring (SCADA). [0003] Conventional FA implementation modes can be divided according to whether communication conditions are required: 1) It does not rely on communication channels, and uses exit circuit breakers or reclosers to sequentially overlap line segment switches (devices) to compl...
