wind power generator load-shedding device

stable safe cheap high quality

Due to the uncertainty of natural winds, though many wind generators have the voltage limiting protective function, we still find that the generators can, in many cases, produce high voltages that are able to damage the downstream grid-connected inversion equipment. As a result, Zhuhai SBT Electric Equipment Co., Ltd. designed a wind power generator load-shedding device to guarantee that the wind power grid-connected inverter will operate at a constant power and the excessive electric energy will be discharged even when the wind power generator’s output is too high. The wind power generator load-shedding device of Zhuhai SBT Electric Equipment Co., Ltd. uses electronic switches, so its response speed is high and it is able to effectively discharge the excessive electric energy, thus guaranteeing the safety of the wind power grid-connected inverter. Generally, one wind power generator needs to be equipped with a load-shedding device whose rated power is the same as that of the wind power generator.
