Abstract: The sagging boom is an important parameter for the safe operation of overhead power lines and can be used as one of the fundamental criteria for the analysis of ice formation intensity. This article discusses the possibility of determining the sagging boom when a sensor phase is fixed to one of the wires, which measures the angle between the wire and the ground plane in the immediate vicinity of the support. To formalize empirical dependence, a full-scale experiment was conducted that simulates the physical properties of the LL wire held on supports. The processing of the obtained data and the approximation of the empirical function were implemented in the MATLAB environment. After processing the data, an empirical function was obtained that can be used in autonomous monitoring systems to control the wire sagging boom.An Autonomous device for monitoring the ice situation on the overhead lines, developed by the authors, for which the empirical dependence was found, al-lows to monitor the intensity of ice formation, as well as to control the mass of ice deposits and the average thickness of the ice wall. Information about the ice condi-tions is transferred to the control station via GSM modem. An autonomous device for monitoring the ice situation on VL wires, developed by the authors, for which the considered empirical dependence was found, allows you to monitor the intensity of ice formation, as well as control the mass of ice deposits and the average thickness of the ice wall. Ice information is transmitted to the control room via the GSM modem. Increasing the intensity of icy deposits causes an increase in the wire sag boom relative to its fluctuations due to process parameters, therefore, the ice monitoring system including analysis of the wire sag angle is an analogue of strain gauges, but does not require reconstruction of the VL and disconnection of the latter during modernization. The device is also equipped with additional sensors, which increases the probability of correct detection of a dangerous ice situation.
Index terms: ice formation, monitoring systems of overhead power transmission lines, wire sagging boom, physical modeling, wire temperature.
