Artykuł przedstawia układ sterowania elektrownią wiatrową z generatorem asynchronicznym klatkowym o mocy 11 kW. Generator asynchroniczny w porównaniu do generatora synchronicznego cechuje niższy koszt i większa niezawodność, jednak ze względu na zjawiska związane ze wzbudzeniem, konieczne jest stosowanie bardziej złożonego układu przekształtnikowego oraz dodatkowej aparatury wspomagającej działanie...
The objective of this paper is to compare two integrator-based controllers, the multi-resonant controller and the direct power control with space vector modulator, with a dead-beat controller for shunt power active filter applications. The three controllers have been compared, theoretically and experimentally, analyzing their robustness, their computational load and their transient and steady-state...
The objective of this paper is to compare two different control structures: the direct power control with space vector modulation (DPC-SVM) and the multi-resonant (MR) current control in a power active filter application, showing their different characteristics and their complementarities. The criteria to choose between both controllers will be mainly the requirements of the application in terms of...
Three-phase PWM (active) rectifiers are connected to the line power through inductance or LCL filter. LCL filter is more effective (better attenuates switching harmonics), however such solution causes stability problems. In order to assure stable operation either a damping resistor or active damping algorithm has to be used. However, extra resistor causes additional losses and active damping algorithm...
