Complex System of Protection of Autonomous Solar Power Plant with Sun-Tracking System

The complex system of protection of a photovoltaic plant against action of overcurrents and currents of an overload, from impulse overvoltages, as well as from the influence of wind load and ice-frost deposits. The review of actions for the protection of a photovoltaic plant against the specified influences is carried out. The necessity of introduction of the presented complex is proved. The scheme of relay protection and automatic equipment of the station and also the scheme of connection of the devices for protection against pulse overvoltage is designed. The features of the choice of the switching equipment for the protection of photovoltaic plant are considered. The events providing protection against wind loadings and snow sticking are held. Thus, the developed complex system of protection will ensure a trouble-free operation of an autonomous solar power station with a dual-axis solar tracker and reliable power supply of electric energy consumers.
