Wind-power distributed generation (DG) converters may inject considerable amount of harmonics into their connected distribution systems that could exceed its connected utility tolerance or IEEE 1547 Std. limits. This paper presents a new adaptive harmonics detection active (AHDA) filter that is designed to suppress harmonics produced by wind DG converters. The AHDA filter consists of an inverter of...
Geomagnetic induced current (GIC) which the geomagnetic storm brings to the power networks can impact the power systems operators, it is necessary to study whether GIC will bring China high voltage direct current (HVDC) transmission systems and ultra-high voltage direct current (UHVDC) power transmission systems serious harms. The models of transfer function which is an effective harmonic analysis...
With the development of superconductive technology of high temperature, multilevel current source converter (CSC) will be widely used in power system. The selected harmonic elimination pulse width modulation (SHEPWM) technique for multilevel CSC is presented in this paper. Simulation results prove the advantages of the method such as low switching frequency, high output current quality, high output...
