Problems solved by technology

In this hierarchical structure, the communication connection between the bottom power distribution equipment, the middle layer and the server is fixed, so when the middle layer fails, the bottom device information cannot be uploaded to the server in time, or the server sends commands to the bottom distribution. electrical equipment, resulting in very serious consequences

Embodiment 1

[0026] This embodiment takes Figure 4 The three-layer distributed power distribution system shown is taken as an example to illustrate the fault handling method in the hierarchically distributed power distribution system. In the actual power distribution system, the top layer is the data processing terminal, which generally refers to the upper computer or cloud that controls and processes data in the power distribution system, and of course other servers that store and process data; the bottom layer is the power distribution terminal, which generally refers to the Power distribution cabinet or distribution box, etc.; an intermediate layer is set between the top-level server and the bottom-level power distribution terminal, which is used to communicate with at least one bottom-level power distribution terminal. Generally, several bottom-level power distribution terminals form a bottom-level power distribution terminal group. Configure a middle tier to communicate with the top ...

Embodiment 2

[0039] Such as figure 2 As shown, Embodiment 2 of the present invention provides a fault handling method for a power distribution system based on hierarchical distribution. The hierarchically distributed power distribution system fault handling method of this embodiment is a follow-up step to the steps in Embodiment 1: within a preset time, generally within 100s, detect all intermediate and bottom power distribution terminals or power distribution terminal groups and The communication connection status between the top-level servers, if the communication connection is possible, switch the bottom power distribution terminal or power distribution terminal group to communicate with the original corresponding middle layer.

[0040] Specifically, when it is detected that a communication connection failure occurs between the underlying power distribution terminal or group of power distribution terminals and the top-level server through the corresponding middle layer, in order not to...

Embodiment 3

[0044] Such as image 3 As shown, the embodiment of the present invention provides a fault handling method for a power distribution system based on hierarchical distribution. The hierarchically distributed power distribution system fault handling method of this embodiment is a subsequent step of the steps in Embodiment 1: when it is determined that the communication connection between the bottom power distribution terminal or power distribution terminal group and the top server fails, the The top level server displays the location of said bottom distribution terminal or group of distribution terminals where the failure occurred.

[0045] Specifically, when it is determined that the communication connection between the bottom power distribution terminal or the power distribution terminal group and the top-level server fails, the top-level server, which in this embodiment is the upper computer, displays the specific location of the failure, so that maintenance personnel can Det...

Abstract

The invention provides a power distribution system fault processing method based on hierarchical distribution, and the method comprises the steps: setting a bottom power distribution terminal or a power distribution terminal group to be in communication connection with at least one intermediate layer except a corresponding intermediate layer, and setting the priority of communication connection; detecting whether the bottom-layer power distribution terminal or the power distribution terminal group can be in communication connection with the top-layer server or not: if not, judging whether a fault occurs in the corresponding middle layer or not; when it is determined that the corresponding middle layer breaks down, matching the bottom power distribution terminal or the power distribution terminal set with the middle layer to be in communication connection with the middle layer according to the set connection priority sequence of the bottom power distribution terminal or the power distribution terminal set and the middle layer. According to the invention, k can switch the bottom power distribution terminal to be connected to the top server through other middle layers at any time, sothat smooth communication between the bottom power distribution terminal and the top server is guaranteed, major power accidents are avoided, and normal operation of a power system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a fault handling method for a power distribution system based on hierarchical distribution. Background technique [0002] In the current intelligent power consumption environment, the power distribution system is generally distributed based on a hierarchical structure. The most common is the three-level interaction mode between the bottom power distribution equipment, the middle layer and the server, that is, one or a group of bottom power distribution equipment will The real-time data is uploaded to the corresponding middle layer, and sent to the server through the middle layer for data processing, and the server can also send commands to the underlying electric equipment through the middle layer. In this hierarchical structure, the communication connection between the bottom power distribution equipment, the middle layer and the server is fixed, so ...
