MULTIFUNCTIONAL MONITORING SYSTEM FOR OVERHEAD POWER LINES
The ability to provide high-quality uninterrupted power supply is largely determined by the reliability of overhead power lines (OHL). Overhead power lines are prone to numerous accidents associated with wire breaks due to ice formation. Today, the diagnostics of ice sediments on wires is performed visually. Existing monitoring systems for overhead power lines are intended for use exclusively in ice deposit conditions and have a small amount of functionality. The article proposes a concept of a multifunctional measuring system designed to provide diagnostics of ice formation, line overload, degradation of wire material, light marking of line spans for aircrafts, and bird scaring. This is achieved through the use of signal ball-shaped markers as part of the measuring system, equipped with sensors for changing the curve of the sagging of the wires or used as optical markers of the position of the wires. The article describes two options for the technical implementation of this measuring system, taking into account the use of one or more marking balls among the set of balls installed exclusively for marking the overhead line span. A conclusion is made about the prospect of introducing the proposed measuring system on especially critical sections of overhead lines with the aim of subsequent transformation of the classic electrical network into a “smart” power supply system.
