Description

A kind of transmission line fault detection method
Technical field
The present invention relates to electrical power trans mission/distribution system technical field, and in particular to a kind of transmission line fault detection method.
Background technology
With the continuous development of science and technology, computer has penetrated into world every nook and cranny.Power system also can not keep away Enter the microcomputer control epoch with exempting from, comprehensive automation system of transformer substation replaces traditional transformer station secondary system, it has also become when The trend of front power system development.Existing comprehensive automation system of transformer substation generally only with and control and protection unit, promptly The means of manual operation breaker tripping and closing, without real-time monitoring system.There is no control, monitoring, measurement and the function of reporting to the police.Generally, Transformer station needs separately to set telecontrol equipment and operator on duty, and deployment cost is high, also higher for the specialty requirement of operator on duty, needs Want operator on duty in time to pinpoint the problems and find out failure cause, make corresponding process.Therefore, existing transformer station does not have intelligence The monitoring system of energyization, security reliability is not high, it is impossible to meet unattended.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of transmission line fault detection method, and the method is simple, convenient, can Transmission line of electricity is broken down and is reported to the police, remind duty personnel to be disposed in time.
To solve above-mentioned technical problem, the present invention is employed the following technical solutions：
（1）Obtain current context information, video information and the transmission line of electricity multidate information of current environment；
（2）The environmental information and video information of acquisition are analyzed and are stored；
（3）The electrical characteristics of measurement transmission line of electricity, and the control parameter related to measured value is extracted from the electrical characteristics of transmission line of electricity；
（4）Current context information, video information and transmission line of electricity multidate information according to front environment, the microclimate condition prison for measuring Survey the sag situation and angle of wind deflection of transmission line of electricity；
（5）The movement position track of transmission line of electricity is monitored according to the data analysiss of sag situation and angle of wind deflection；
（6）Coordinate diagram is drawn to movement locus, if movement locus exceed normal line track-bound, alarm equipment alarm otherwise, is surveyed The aeolian vibration level of amount data monitoring transmission line of electricity and fatigue life；
（7）Aeolian vibration level and fatigue life are analyzed and are stored, if marginal value or beyond value is closed on, is then counted this Shown to display device according to information output, and alarm.
The invention has the beneficial effects as follows：Transmission line fault detection method of the present invention, realizes power transmission line sag, covers The reliable on-line monitoring that ice, windage yaw, wind are put, wave etc., effectively prevention and reduces grid power transmission circuit accident.

S2：The environmental information and video information of acquisition are analyzed and are stored；
S3：The electrical characteristics of measurement transmission line of electricity, and the control parameter related to measured value is extracted from the electrical characteristics of transmission line of electricity；
S4：Current context information, video information and transmission line of electricity multidate information according to front environment, the microclimate condition prison for measuring Survey the sag situation and angle of wind deflection of transmission line of electricity；
S5：The movement position track of transmission line of electricity is monitored according to the data analysiss of sag situation and angle of wind deflection；
S6：Coordinate diagram is drawn to movement locus, if movement locus exceed normal line track-bound, alarm equipment alarm otherwise, is surveyed The aeolian vibration level of amount data monitoring transmission line of electricity and fatigue life；
S7：Aeolian vibration level and fatigue life are analyzed and are stored, if marginal value or beyond value is closed on, is then counted this Shown to display device according to information output, and alarm.
Those skilled in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention, And be not used as limitation of the invention, as long as within the spirit of the present invention, being made to above example It is appropriate to change and change all to fall within the scope of protection of present invention.
