SYSTEM FOR AUTONOMOUS POWER SUPPLY OF LOADS Russian patent published in 2010 - IPC F03D9/02 H02K7/18 H02J7/34 

FIELD: electricity.

SUBSTANCE: invention is related to the field of electrical engineering and wind power engineering, namely to autonomous systems of power supply, providing high-quality electric energy to loads distanced from system of centralised power supply. Proposed system comprises wind power plant, which is connected to common busbars via rectifier, inverter, stabiliser, reverse current relay, accumulator battery, connected between rectifier and inverter, autonomous source of power supply, working on organic fuel, equipped with synchroniser and controller of generated power. At the same time, according to the present invention, unit of signal generation is connected to inlet and control circuits of inverter, and it generates signals of certain shape depending on pulsations and value of rectified voltage. System also comprises unit for control of power supply sources operation modes, including time relay, intermediate relay, current and voltage relay contacts. Stabiliser and relay of reverse current are installed downstream inverter, accumulator battery is connected to inverter via diode and is charged from double-staged charging device, which is connected to common busbars via contactor, which provides for high-quality charging. In circuits of autonomous power supply source, electric energy consumer and circuit of charge there are current relays installed, and downstream rectifier there is voltage relay connected, while accumulator battery and rectifier are connected to inverter via contactors.

EFFECT: expansion of wind power plant resources in generation of high-quality electric energy, provision of reliable power supply and saving of organic fuel by matching of power supply source sources operation modes, prolongation of accumulator battery service life.
