Embodiment 1

[0038] A typical distributed feeder automation system diagram is shown in figure 1 As shown, the specific steps are:

[0039] 1. Configure feeder topology

[0040] STU1 will record the communication address of the machine and the name of the switch in the area. STU1 will configure the switch S11 as a power switch, S12 as a common segment switch, and S13 as a load switch, and record the connection relationship between the switches. Since the side of S13 is connected to STU 2 The management topology unit is connected, so the adjacency address on one side will be recorded as the communication address of STU 2. By analogy, the distributed topology information configuration of all power distribution terminals in the area can be completed.

[0041] 2. Dynamic identification of contact switch

[0042] Combine below figure 1 The feeder structure is shown, and the process of dynamic identification of the tie switch is explained step by step.

[0043] (1) STU3 detects that the swit...

Abstract

The invention provides a multi-interconnection feeder line interconnection switch dynamic identification method comprising the steps that each power distribution terminal stores topological configuration information within respective coverage, wherein the topological configuration information includes the switch type and the switch adjacency relation; the master control power distribution terminal starts interconnection switch identification and constructs feeder line topology of the two sides of a target switch based on information interaction between the power distribution terminals; and whether the target switch is the interconnection switch is judged according to the feeder line topology and the switch state. The method is an important component of feeder line topology dynamic identification and a basis for generating a multi-interconnection power distribution network intelligent distributed feeder line automatic system power supply recovery scheme.

Description

technical field [0001] The invention relates to a dynamic identification method for a tie switch, in particular to a dynamic identification method for a multi-tie feeder tie switch. Background technique [0002] Intelligent distributed feeder automation system can realize rapid fault isolation and power supply restoration of feeder, which is an effective means to improve power supply reliability. The system does not depend on the master station, avoids the delay caused by the large amount of information transmission, improves the response speed, and utilizes the information interaction between multiple stations to realize the optimization of the control strategy, which has become a hot research topic in current automation. Tie switch control is the basic means of the power supply recovery scheme of the intelligent distributed feeder automation system. However, changes in the operation mode of the distribution network often cause changes in the tie switch, so the independent ...
