Description

A kind of power tower bar fault remote monitoring scheme and device

Technical field

The present invention relates to a kind of power tower bar fault remote monitoring scheme and device, the problem such as tilt, electric wire pendency angle is abnormal, phase voltage is abnormal mainly for tower bar and be monitored.

Background technology

Along with developing rapidly of China's electric utility, transmission line of electricity coverage is increasingly wider, and wiring becomes increasingly complex, and as the important node ensureing transmission line of electricity normal operation, the malfunction monitoring of power tower bar is always the most important thing. On the one hand, in the urban area of power tense, line density is big, and tower bar quantity is many, makes an inspection tour maintenance workload huge; On the other hand, at the high-voltage power tower bar of the Special zone such as countryside, wilderness, upland meadow, due to a varied topography, dangerous, patrol route is long, not only increases working time and the intensity of tour personnel, it is also possible to jeopardize personal safety.

In addition, staff needs to carry with some circuit data in tour process, in order to inquiring about in tour process, also needing to carry extensive work apparatus, for instance mobile phone, photographing unit, GPS locator, transmitter receiver etc., instrument is many, troublesome poeration, burden also weighs. The working method of current domestic commonly used manual patrol hand-made paper medium recording, this mode also exists the problems such as tour cycle length, labor intensity is big, risk factor is high, and there is tour blind area. Also have some areas to adopt helicopter aerophotographic method, take helicopter and patrol and examine along the line, adopt video camera and other Detection Techniques that tower bar is checked, although this mode motility is high, broad view, but cost is big, and have certain flight hidden danger.

Summary of the invention

It is an object of the invention to, design set of device also proposes a kind of scheme and remotely monitors power tower bar malfunction, and is accurately positioned fault tower bar position when fault occurs.

For realizing object above, by the following technical solutions: installing monitoring device on power tower bar, this device uses single-chip microcomputer to be controlled, and has economy and reliability concurrently. The pendency radian of tower bar inclination angle and power transmission line is measured by angular transducer, each phase voltage monitored by voltameter, and utilize GPRS communicator to transmit data to the control centre in a distant place, these data and normal parameter are compared by control centre, if beyond normal range, then trigger fault early warning the tower bar corresponding to abnormal data generate a Trouble Report, it is achieved the monitoring in real time of fault and quickly reply.

This programme has the advantage that one is that real-time is high, and Monitoring Data is sent to control centre in real time, it is possible to find and position fault tower bar in the very first time; Two is good economy performance, adopts GPRS technology to carry out data transmission, utilizes existing network, saves the investment building wireless communication networks;Three is that malfunction monitoring is comprehensive, contains power tower bar, power transmission line, phase voltage etc. multiple it may happen that the part of fault, it is possible to monitor most fault.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is further described.

Monitoring device (Fig. 1) is mainly used in measuring and transmit the angle of inclination of power tower bar, the power transmission line pendency parameter such as radian and phase voltage in real time; therefore the measurement module being made up of two angular transducers and three voltameters (being used for measuring each phase voltage) is mainly included; the supply module being made up of solaode and charging circuit; GPRS communication module and single chip control module, in addition with the field such as lightning protection, protection against the tide design protection.

It is responsible for receiving the control centre of data to need to set up corresponding data base and deposit the monitoring numbering of device, positional information and each device and send the data etc. of coming, and coding judges data whether it is normal, as shown in Figure 3. Initially set up system model:

$u=\underset{i=1}{\overset{5}{\Σ}}y\left(A_i\right)|A_i-A_{i0}|,i=1,2,3,4,5---\left(1\right)$

Wherein A₁For tower bar measurement of dip angle value, A₂For power transmission line overhanging corner measured value, A₃,A₄,A₅For each phase voltage. A_i0(i=1,2,3,4,5) represent the ideal value corresponding to each parameter, y (A_i) representing the weight function that each parameter is corresponding, its function curve all can be set to shown in Fig. 2, y_i0Represent corresponding parameter A_iCritical weights, more than y_i0Show this abnormal parameters. The ideal value of each parameter can be adjusted accordingly according to the difference of the physical conditions such as tower bar type, geographical environment, and weight function can be manually set according to parameter change rate, so that each y (A_i)|A_i-A₀| ideal value keep roughly equal. The measure of correspondence is taked according to the u value size finally obtained. U value is more little, it was shown that surveyed data are closer to ideal value, and tower bar is in normal condition, otherwise, then illustrate that data measured and ideal value deviation are bigger, it is necessary to overhaul. According to practical situation, u can be divided into multiple section, for three sections:

As u≤u₁Time, each parameter is normal, and staff carries out regular maintenance;

Work as u₁<u≤u₂Time, it was shown that there occurs minor failure, staff carries out emergent maintenance;

Work as u > u₂Time, it was shown that there occurs catastrophe failure, personnel's emergency service of should arranging work immediately.

According to above scheme, design specific procedure flow process is as it is shown on figure 3, step is as follows:

1. control centre sets u₁,u₂,A_i0, y (A_i), y_i0, i=1,2,3,4,5.

2. the measurement data A from monitoring device is received₁,A₂,A₃,A₄,A₅, calculate the weights y (A of correspondence respectively_i)。

3. substitute into formula (1) and calculate u value, if u≤u1, return 2.; If u1 is <u≤u₂, trigger minor failure early warning and turn 4.; If u > u₂, trigger catastrophe failure early warning and turn 4..

4. y (A is compared_i) and corresponding y_i0, export and all make y (A_i)>y_i0The corresponding A set up_iValue.

Staff will retrieve the positional information of corresponding monitoring device according to program output from data base, and according to exceptional value A_iPreliminary judgement failure cause, thus realizing quickly finding fault, fault point.

It is understood that the system structure shown in figure is not intended that the restriction to system, it is possible to include ratio and illustrate more or less of equipment, or combine some equipment, or different deployed with devices.

Above; being only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any those familiar with the art is in the technical scope that the invention discloses; change can be readily occurred in or replace, all should be encompassed within protection scope of the present invention. Therefore, protection scope of the present invention should be as the criterion with scope of the claims.
