Embodiment

[0035] If a new feeder F1 needs to be added, the feeder needs to be initialized and configured, such as figure 2 As shown, the process is as follows:

[0036] Step 1. Upload the ICD files of all STUs on feeder F1 to the master station;

[0037] Step 2. The master station detects that its internal terminal IP table does not contain the IP address provided by the ICD file, and immediately updates the terminal IP table. At the same time, select / subscribe according to the functional services provided by the ICD file.

[0038] Step 3. The master station imports all the selected / subscribed ICD files and the FSD file describing the feeder topology into the feeder configuration tool to generate a new FCD file;

[0039] Step 4. The master station imports the FCD file into the device configuration tool, uploads it to the monitoring background, and imports the configuration database backup.

[0040] Step 5. Each STU downloads and obtains a CID file from the device configuration tool....

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, a feeder automation system configuration method based on station-side coordination adopted in this embodiment specifically includes the following steps:

[0045] Step 1. When the f...

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 feeder automation system configuration method based on station end cooperation. Flexible configuration of the system is realized, and the problem of incorrect terminal adjacency relation caused by misoperation of configuration personnel in the configuration process is solved. On one hand, the main station is responsible for updating and maintaining the whole network topology; on the other hand, when the distributed FA system breaks down or power supply recovery of a non-fault area cannot be realized, the master station takes over the work of fault processing, and corrects the result that the topological connection relationship is disordered due to the incorrect adjacency relationship of the terminals in the distribution line, so that topological information errorscan be found in time, and the situation of positioning errors of the distributed FA system is prevented.

Description

technical field [0001] The invention belongs to the technical field of power distribution automation, and in particular relates to a feeder automation system configuration method based on station-end coordination. Background technique [0002] In recent years, communication, computer, automation and other technologies have been widely and deeply applied in the power grid, and have been organically integrated with traditional power technologies, which has greatly improved the intelligence level of the power grid. The power Internet of Things is an inevitable trend in the development of power grid technology. Power distribution As a key link of the power Internet of Things, the system has attracted the attention of many universities and power companies. At present, 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 the...
