Embodiment example 1

[0026] Implementation case 1: Use the "National Taxation Bureau" as the power outage unit to locate the power outage fault;

[0027] Implementation process: In the event of a fault, the secondary equipment (i.e. data acquisition equipment - FTU, TTU, BTU, etc.) of the "National Taxation Bureau" line branch collects the current and voltage mutations at the fault point, and the switch displacement information will be uploaded to the main station in real time database server. The emergency repair command personnel of the distribution network log in to the system management workstation to access the server of the fault research and judgment system; enter "National Taxation Bureau Change" in this system, such as figure 2 As shown; at this time, the fault research and judgment system server will obtain the geographical coordinates of the data (such as lines, distribution transformers, line towers) in the geographic information database server GIS, and the primary equipment informat...

Embodiment example 2

[0028] Implementation case 2: Taking "single user power outage" as the power outage unit to conduct power outage fault research and judgment;

[0029] Implementation process: When a single user loses power, the system can conduct fault research and judgment. Enter the information in the system for the specific outage customer "test user 1", and you can find the relevant information about the specific power outage customer "test user 1", such as image 3 shown. If you want to judge whether it is a regional power outage or an internal failure of the user, you can click the upper level "Cooperation Lane Distribution Transformer" to which "Test User 1" belongs, such as Figure 4 As shown, you can see other users "Test User 2" of the same level related to "Test User 1". Through the comprehensive comparison and analysis of the data collected by the CTU of "test users 1 and 2", it is finally judged whether it is an internal failure of a single user or a power outage due to a region...

Abstract

The invention provides a distribution network fault judgment searching and positioning system which belongs to the technical field of power engineering. A data acquisition device of the system is used for acquiring the state information of a distribution network, and transmitting the state information of the distribution network to a main station database server through a dedicated power communication network. GIS is used for storing and updating geographic information. PMIS is used for storing and updating the parameter information of a transformer and a transmission line. A fault judgment system server is used for providing the functions of fault information retrieval, fault diagnosis, data management analysis, graph processing and information dissemination. According to the invention, distribution network power cut and transmission information query retrieval, failed equipment searching and positioning and online graph display can be carried out; when the distribution network is failed, the system can help emergency repair staff to carry out quick fault point positioning and fault judgment; outage time is effectively shortened; outage range is prevented from expanding; valuable repair time is saved; and the system is fast, flexible and accurate.

Description

technical field [0001] The invention relates to a distribution network fault research, judgment, search and positioning system, which belongs to the technical field of electric power engineering. Background technique [0002] The distribution network emergency repair command business is based on distribution network regulation and is responsible for receiving work orders for fault repairs within the jurisdiction, research and judgment of equipment faults, order dispatching, work order tracking and supervision, review of return orders, and production power outage information The collection, editing, submission and other specific businesses of the project, the quality of its work has a greater impact on improving the quality of power supply services. Compared with the main network, the distribution network has its obvious characteristics. The main network equipment is mainly concentrated on several "nodes" (factory stations), which are relatively neat, while the distribution n...
