Features of Alternative Power Supply of Weather Stations for Monitoring the Condition of the Roadway

In the winter period there is a task of timely control over the condition of the roadway. The formation of snow and ice on intercity roads increases the likelihood of accidents. One of the options to reduce accidents is to control the condition of the roadway and climatic parameters that lead to these natural phenomena with the help of weather stations with a set of different sensors. The location of weather stations along the roads will allow to control the parameters of the condition of the roadway in a timely manner and take measures to parry critical situations. The paper discusses options for alternative power supply of weather stations located away from power grids along intercity roads. The paper considers the possibilities of powering weather stations for condition monitoring from the three-phase grid, powering from solar panels and powering from wind installations. It is proposed to apply a complex power supply to realize the uninterrupted operation of the weather station in winter
