Embodiment 1

[0043] When the function of the STU on the feeder is upgraded or the communication interface is changed, the function upgrade of a certain STU or the change of the communication interface is actually a change in a single ICD file, which does not involve the configuration of the feeder topology connection relationship, so the configuration process does not need an FSD file Participation. When the STU function is upgraded, the master station needs to re-select the subscription, and the CID of the adjacent STU does not change. When the communication interface changes, the master station does not need to re-select the subscription, and the CID of the adjacent STU changes. At this point, the configuration information can be modified in a local-to-global manner.

[0044] Therefore, if image 3 As shown, the master station-based distributed feeder automation system configuration method proposed by the present invention specifically includes the following steps:

Embodiment 2

[0053] Compared with the substation, when IEC61850 is applied to the distribution network, the configuration process and method of the system are different. In terms of files, the original SCD file corresponds to the feeder configuration FCD file, and the original SSD file corresponds to the feeder specification description FSD file. In the distribution network, there are a large number of feeders. For the convenience of management, each feeder has an independent FCD and FSD file, while the entire substation system only has one SCD file and SSD file; in terms of configuration, due to the new IID and SED Class files make the configuration methods more flexible and diverse, and a reasonable choice of configuration methods can reduce the configuration workload.

[0054] When a new STU is added on the feeder, when the structure of a certain feeder changes slightly, such as adding or deleting a group of STUs, it is still possible to modify the configuration information from the loca...

Abstract

The invention discloses a distributed feeder automation system configuration method based on a master station. The method comprises the following steps: when an STU function upgrading or communicationinterface on a feeder changes, uploading an ICD file of a new STU to the master station; detecting the IP address of the STU has already existed in the IP table of an internal terminal by the masterstation without the need of updating the IP table of the terminal, guiding the ICD file of the STU into a device configuration tool, and generating an IID file; or, updating the IP table of the terminal instantly, and carrying out selective subscription according to functional service provided by the ICD file; guiding the generated IID file into a feeder configuration tool by the master station, calling an original FCD file from a configuration database, amending the original FCD file to generate the new FCD file to be guided into the device configuration tool, and uploading the FCD file to amonitoring background and baking up the FCD file in the configuration database; and downloading a corresponding CID file from the device configuration tool by the STU and the adjacent STU. The error of topological information can be discovered in time, the positioning error condition of a distributed FA system is avoided, and the method is more flexible and reliable.

Description

technical field [0001] The invention relates to a master station-based configuration method for a distributed feeder automation system, belonging to the technical field of power distribution automation. Background technique [0002] In recent years, communication, computer, automation and other technologies have been widely and deeply applied in power grids, and have been organically integrated with traditional power technologies, greatly improving the intelligence level of power grids. Smart grids are an inevitable trend in the development of power grid technology. Power distribution systems As a key link of the smart grid, it has attracted the attention of many universities and power companies. At present, distributed feeder automation (FA) technology has gradually become a research hotspot in the field of distribution automation because of its characteristics of accurate positioning and rapid action in fault handling. Among them, a reasonable configuration method can red...
