High voltage line wind deviation online monitoring system and method based on vibration power generation

Abstract

The invention provides a monitoring system and a method for precisely measuring high-voltage line windage. The system is composed of a windage monitoring device, a meteorological monitoring device, a monitoring base station and a monitoring centre. Functions of acquisition and transmission of windage and meteorological data, failure pre-warning, real-time control and data processing and displaying are realized. The windage monitoring device comprises a sensor module, a signal modulating module, a signal control and wireless transceiving module, a GPS (Global Position System) module, an MCU (Micro Control Unit) and a vibration power generating module. The device is unnecessary to be additionally provided with a power supply. The power of the device is completely supplied by the miniature vibration power generating module. A field monitoring device transmits data to the monitoring base station through a short-distance wireless communication module. Then, the data is sent to the monitoring centre through a GPRS (General Packet Radio Service) network of the base station. The monitoring centre also can reversely transmit instruction so that the operation state of the device is adjusted. Simultaneously, the windage monitoring device is designed in a low-power-consumption mode integrating dormancy, standby and timed transmission. A mechanism for automatically rousing by exceeding a preset threshold is operated. The system and the method disclosed by the invention are applicable to online-monitoring a high-voltage line.

Description

technical field [0001] The invention relates to an on-line monitoring system and a method for accurately measuring the wind deflection of high-voltage lines, which are suitable for high-voltage transmission lines and belong to the technical field of industrial detection systems. Background technique [0002] The wind deflection of the transmission line includes the string wind deflection of the insulator of the linear tower, the wind deflection of the jumper wire of the tension tower and the interphase wind deflection of the conductor. discharge between. Wind deviation faults of transmission wires generally occur in strong winds and are usually accompanied by rain, snow or hail. The performance is as follows: strong winds cause the insulator strings or wires to swing greatly, and the live lines are kept close to the tower body due to the continuous wind force and maintained for a long period of time. , Due to the insufficient air gap distance, the line discharges to the tow...
