A novel control strategy for solving unbalanced three-phase load in low voltage power grid is proposed in this paper. The compensating current determined by a new method based on instantaneous voltage vector orientation, which overcomes the shortcomings of phase-locked loops (PLL) in the traditional detection methods. A static var generator (SVG) is employed to compensate the unbalanced current obtained...
Aiming at the problems of environmental parameter detection are different in a variety of occasions, this paper proposes a kind of multi-parameter environmental monitoring scheme, the scheme provides a tower environment monitoring device, system structures method and multi sensor information fusion algorithm. Using this scheme can monitor, display a variety of local environment parameters, and upload...
A novel topology with a bi-directional DC/DC for stand-alone wind power system is adopted, which can maximize the battery life by monitoring and controlling its state of charge(soc) and charge/discharge process. According to the atmospheric conditions, the state of charge of the battery and the load conditions, six possible operation modes of the bi-directional DC/DC are also expounded. This paper...
