Electrical three phase circuit analysis using quaternions

Abstract: Nowadays, reactive power and power factor in unbalanced circuits and/or with the presence of harmonics are still being investigated by several researchers. In this context, quaternions, whose use has recently been intensified in the electrical engineering field, is presented as an alternative tool to analyze electrical quantities in single and three-phase circuits. However, studies solving three-phase circuits by quaternions are not yet in literature, nor a complete electrical description with this tool. This … Show more

“…In this paper, we extend the previous work of [10] for quaternion power analysis, highlighting the relation between power and load. In [10], the quaternionic power for a load was described in terms of quaternionic impedance but only for a balanced load in Y configuration. Here, we study the quaternionic power for a general (balanced and unbalanced) load in ∆ configuration.…”

“…Fully capturing the evolution of state vector estimation error terms requires close scrutiny of the ACF impact on state vector estimation errors. This is achieved through formulating (38) in a network-wide format as (39) where {P n ,Q n ,G n } are the block-diagonal matrices…”
