Harmonics and reactive currents detected in precision is the key whether active power filters work well. Methods on detecting affect compensation currents and detecting precision. A novel harmonics and reactive currents detecting algorithm in three phase circuit is proposed. It extracts positive fundamentals of source voltages and load currents using three-phase sinusoid and cosine signals with arbitrary phase, and then detects harmonics, reactive and negative currents by accurately separating positive fundamental active component from load currents. Whether waveforms of voltages are non-sinusoidal or unbalanced, the results can not be affected. Furthermore, it is without phase lock loop. Finally, it is proved to be precision and feasibility from simulation.

Definition Of

This paper presents a new framework based on geometric algebra (GA) to solve and analyse three-phase balanced electrical circuits under sinusoidal and non-sinusoidal conditions. The proposed approach is an exploratory application of the geometric algebra power theory (GAPoT) to multiple-phase systems. A definition of geometric apparent power for three-phase systems, that complies with the energy conservation principle, is also introduced. Power calculations are performed in a multi-dimensional Euclidean space where cross effects between voltage and current harmonics are taken into consideration. By using the proposed framework, the current can be easily geometrically decomposed into active- and non-active components for current compensation purposes. The paper includes detailed examples in which electrical circuits are solved and the results are analysed. This work is a first step towards a more advanced polyphase proposal that can be applied to systems under real operation conditions, where unbalance and asymmetry is considered.
