Abstract
The invention discloses a power supply failure recording system with a GPS (global positioning system) clock, which belongs to the technical field of maintenance and management of the power industry. Each of all stations of a wireless network based on a topological structure is provided with a failure recorder, each recorder consists of four functional modules respectively realizing 1 receiving a GPS time service signal and providing high-precision time synchronous signals, 2 recording and storing power supply technical data of the corresponding station, 3 recording and storing administrative duty information of the corresponding station and 4 receiving and transmitting monitoring network connection signals. The power supply failure recording system has the advantages that each distribution station or room in a monitoring network is provided with a failure detector with a GPS time service module, power supply technical parameters and maintenance attendant information of the stations of basic levels are recorded and stored in memories, the information is received by a main control panel at any time so as to be analyzed, accurate reference data are provided for power scheduling, abnormal power supply conditions can be accurately judged before failures occur, and accident potential is killed in the bud.
Description
Technical field
The invention belongs to power industry maintenance management technical field.
Background technology
Electric power system has numerous distribution substations, switchgear building, and scale and how many difference of maintainer are very big, and the reason and the probability that break down have nothing in common with each other.In traditional management mode, larger station usually be equipped with more advanced testing equipment, the less maintainer that the station then relies on of scale carries out artificial observation.Because electric power system is not independent one by one base station, many operation troubless are because the abnormal conditions of power supply network cause, and also possibly be that some very little power supply units are failed in time to fix a breakdown and caused the fault of wider electric power system.Therefore, accurately judging the abnormal electrical power supply situation, eliminate accident potential in bud, is the important topic that electric power system faces.
Summary of the invention
All websites that the objective of the invention is in a power supply trouble monitoring network are equipped with the trouble recorder with GPS time service function, with accurate location and failure judgement phenomenon.
Technical scheme of the present invention is: the present invention is based on the wireless network of topological structure, its all websites all are equipped with a trouble recorder, and this registering instrument is made up of four functional modules: 1, receive the GPS time signal and the split-second precision synchronizing signal is provided; 2, record stores the power supply technique data of this website; 3, record stores the information administrative on duty of this website; 4, reception and transmitting supervisory net cue.
Beneficial effect of the present invention: a fault locator that has GPS time service module is installed in each distribution substation, the chamber in monitoring network by this system; With basic unit's website power supply technique parameter with safeguard that operator on duty's information recording storage is to storer; Supervisory control desk receives above-mentioned information at any time and carries out analyzing and processing; For power scheduling provides reference data accurately, can accurately judge the abnormal electrical power supply situation before making fault take place, accident potential's elimination in bud.
Embodiment
The present invention is based on the wireless network of topological structure, its all websites all are equipped with a trouble recorder, and this registering instrument is made up of four functional modules: 1, receive the GPS time signal and the split-second precision synchronizing signal is provided.In view of GPS time service receiver module product miniaturization at present, modularization, and cost reduces greatly, for condition has been created in wider use, and the HJ5441 type Embedded GPS clock module that the trouble recorder among the present invention uses.This module uses crystal oscillator to tame lock-in techniques, and crystal inside oscillator output frequency precision is locked on the gps signal, for the powered operation data of trouble recorder provide accurate clock signal.
2, record stores the power supply technique data of this website.Collection, processing and the storage of power supply critical data are carried out according to the electric power system industry standard, adopt unified statistics form, for the supervisory control desk data processing facilitates.
3, record stores the information administrative on duty of this website.The information administrative on duty of each website comprise in real time take personal charge of the shift, operator on duty's content, the specifying information in orientation, each time period operator on duty's detail list and calendar information after this on duty before this.
4, reception and transmitting supervisory net cue.At any time receive the contact information of supervisory control desk, and send the relevant information of our station trouble recorder according to instruction.Storer internal information retention time is no less than 1 year.
Claims (3)
1. be with the power supply trouble register system of gps clock; The present invention is based on the wireless network of topological structure; It is characterized in that: its all websites all are equipped with a trouble recorder, and this registering instrument is made up of four functional modules: 1, receive the GPS time signal and the split-second precision synchronizing signal is provided; 2, record stores the power supply technique data of this website; 3, record stores the information administrative on duty of this website; 4, reception and transmitting supervisory net cue.
