WIND-DIESEL SYSTEM FOR INDEPENDENT POWER SUPPLY

摘要

FIELD: power supply.;SUBSTANCE: invention relates to power supply. Wind and diesel system of autonomous power supply comprises wind generator, diesel generator, two rectifying and charging devices, storage battery, inverter, wherein outputs of wind generator and diesel generator are connected to inputs of rectifiers-chargers, whose outputs are connected to storage battery and form DC bus. System further includes distributing device for connection of electric receivers, sensors of power wind generator, diesel generator and load, adder, comparison elements, generators of electric receivers rated power, units of resolution of connection with control buttons. Inputs of sensors power wind generator and diesel generator are connected to information outputs of wind generator and diesel generator respectively, outputs are connected to inputs of Adder, which output is connected to first input of first comparator, which second input is connected to output of load capacity sensor, which is connected between DC bus and inverter input. Inverter output is connected to input of switchboard and forms AC bus, distributing device is made in form of switches with control inputs, which are connected to outputs of blocks on switching on resolution, which inputs are connected to outputs of comparators according to number of electric receivers, first inputs of comparators are connected to outputs of setters of nominal power of electric receivers, second are connected to output of first comparator.;EFFECT: technical result is increase in reliability of power supply and reduction of installed capacity of electrical equipment.;1 cl, 2 dwg
