Technical field
The present invention relates to a kind of transmission line galloping monitors field on-line, more particularly to it is a kind of based on big-dipper satellite positioning system
The transmission line galloping on-line monitoring method of system.
Background technology
Transmission line of electricity is affected by a natural to occur that circuit is waved, and line oscillation is a kind of more serious natural calamity
Evil, China is also the country of line oscillation disaster most serious.Line oscillation easily cause circuit phase fault, relative ground circuit,
Insulator is damaged, wire fracture, causes circuit to fall tower when serious, and causes grid power blackout accident.
Waving for transmission line of electricity generally refers to transmission line of electricity under the excitation of wind, produces a kind of low frequency（About 0.1HZ ~
3HZ）, large amplitude wire self-oscillation.Its amplitude can reach 5 ~ 300 times of transmission line of electricity, and amplitude peak can reach more than 10 meters.
Half wave number of transmission line galloping is very big to the waveform influence waved, the general situation for only considering 1,2,3,4 half-wave,
5 and the throw amplitude value meeting very little of the wave number of the above half, will not cause the failure of transmission line of electricity, so not considering.
China is affected very big by transmission line galloping side, and south from Hunan, north, to northeast, is all frequently to receive disaster area, scope

Base station modem is that error point signal is encoded and modulated, and is input to radio station, then is sent by radio station,
Receive for mobile receiving station and utilize.Radio station receives the error signal of modulator coding, utilizes for mobile receiver, calculates movement
The accurate location of receiver, and accurate position signalling is sent into base station by station radio is moved.GPRS communication modules are used for
Base station will be sent to terminal control office by the precise position information of movement station, can use 2G, 3G or 4G network.
Data-Link module includes in mobile station receiver：Modem and radio station.
Mobile station modems are exact position Signal coding and the modulation after movement station is calculated, and are input to radio station,
Sent by radio station again, received for base station.
In addition, radio station is used uniformly across ground wave transmission, operating distance is fully sufficient, and installs simply, and 25W power is also very
It is little.
Software analysis processing module：
For analyzing three dot position informations, the concrete waveform of transmission line galloping can be analyzed according to concrete data, be simulated defeated
The track that electric wire number is waved, then sends trace information, and for monitoring center the signal of whether early warning or maintenance is sent.
Imaging: Monitoring module and alarm module：
Transmission line galloping track is shown in real time according to analysis result, according to trace information, is made whether to send line oscillation pre-
Alert signal.
Power module：
Using one or more in battery, sensing electricity getting device, vibration energy taking device.
It is an advantage of the invention that：
Real-time, continuity, accuracy that the present invention is positioned by the Big Dipper, can realize round-the-clock to transmission line galloping track
On-line monitoring.
