Each main devices specific explanations is as follows:
Wind/light complementation controller: mainly with wind-light-electricity after over commutation, pressure regulation etc. are processed, electric energy is saved in the energy-storage battery with galvanic form, operation principle is as follows: 1, wind-driven generator produces unsettled alternating current under the wind-force effect, through the arrangement of arrangement diode, capacitor filtering, DC voltage stabilizing processing etc., the direct voltage of stable output, this direct voltage connect battery, when the battery power shortage time, rely on wind-force to charge the battery; 2 luminous energy photovoltaic panel produce unsettled direct current, process through the DC/DC voltage stabilizing, and output connects battery, when the battery power shortage time, rely on solar panels to charge the battery.Be the aspects such as the efficient that guarantees system, fail safe, system also needs to increase the auxiliary circuits such as brake protection, unloading circuit, warning indication.
Combining inverter: mainly the energy in the energy-storage battery is outputed to electrical network, because battery storage is direct current, pass through contravariant equipment, obtain the alternating current identical with mains frequency, voltage, phase angle; The control element of combining inverter is the MCU control system, and power device is the IGBT device, and auxiliary circuit includes boosting unit, filter unit, detecting unit, communication unit and alarm unit.Small-power is generally single-phase AC220V output, high-powerly accomplishes 3AC output, and product design reserves power regulation functions, possess " isolated island " protects, possesses programmable switch shutdown function.
