Description
Technical Field
The application belongs to the technical field of power transmission lines, and particularly relates to a power transmission line fault monitoring device, method equipment and a storage medium.
Background
The tripping caused by the fault of the transmission line is one of the faults with the highest frequency of the power grid, and the tripping fault has great influence on the safety of the system, the safety of equipment and the reliability of power supply. Due to the fact that the fault reason is judged inaccurately, the pertinence of the adopted protective measures is not strong, and the frequency of power grid fault tripping is difficult to be reduced remarkably. And because the fault is inaccurately positioned, the time consumed for finding and repairing the fault is longer, and certain influence is brought to timely repairing the fault and recovering the power supply. In order to reduce the occurrence frequency of grid fault tripping, the position of a fault point needs to be accurately determined, and the cause of the fault occurrence needs to be determined so as to take a targeted prevention measure.
Each station of the existing power system is provided with a microcomputer protection or microcomputer fault recording device, and analysis data required by power frequency fault distance measurement can be obtained through existing equipment of the system, so that the required cost is low, and the realization is easy. However, in any conventional ranging algorithm, it is necessary to base on one or more assumptions, which are different from the actual situation of the system, and therefore, there is an unavoidable error. Although the accuracy of the algorithm can be improved to a certain extent by error compensation or by adopting multi-terminal line data, the ranging effect is poor under the conditions of high-resistance grounding, multi-power supply lines, open circuit faults, branch lines and the like, and even in the occasions which can be used in the conventional ranging algorithm, the achieved ranging accuracy is difficult to ensure within 1 km.
