Optimized Design of Stationary Frame Three Phase AC Current Regulators

The ability to individually extract different types of disturbances present in AC line currents or voltages is desirable for reference signal calculation algorithms employed in power conditioners, in order to optimize the operation and design of power converters. This paper proposes a novel algorithm based on the dot product of three-dimensional space vectors in the abc coordinate system, for real-time calculation of the instantaneous positive-, negative-and zero-sequence components for individual harmonics. Certain applications are presented, including individually compensating the fundamental reactive power, selected current harmonics and current unbalances. This method is computationally simple and requires no coordinate transformation. The proposed algorithm is validated by simulation and experiments.

Abstract-This work reviews the state-of-the-art in the field of harmonic resonance problems in Wind Power Plants (WPPs). Firstly, a generic WPP is modeled according to the equivalent circuits of its passive and active components. Main focus is put on modeling active components, i.e. the ones based on power converters. Subsequently, pros and cons of frequency and time domain analysis methods are outlined. The next sections are devoted to mitigation methods implemented in the power electronics converters. From the wind turbine perspective, different techniques to enhance the robustness of the controller are analyzed. Subsequently, the suitability for active damping of harmonics using STATCOM devices is assessed, with focus both on control techniques and power converter technologies.

“…Therefore, determination of these parameters is essentially required for analyzing the machine model. There are several works [6], [9] executed which assumes the machine inductance to be constant for simplicity of the model although different other works [4], [7]and [8] dynamically estimate the inductance through FEM and field analysis and control [10][11][12][13][14][15] for getting correct results. In this paper, the machine under consideration is an axial flux machine and the mover is having a non-magnetic structure, which is aluminium.…”
