A comparative analysis of FBD, PQ and CPT current decompositions — Part I: Three-phase, three-wire systems

A review and insights on Poynting vector theory and periodic averaged electric energy transport theories

“…i k is orthogonal current. FBD [11] decomposes the components into an average power component and a fluctuations component, and also breaks the components into the prime harmonic of the active, inactive and the rest of the harmonics [6]. CPC decomposes the current/power into five meaningful components [3].…”

“…As a result, instantaneous radiation phase-to-phase interaction [34], which contributes zero periodic energy, also appears. Only the periodic averaged active power and instantaneous power measurements succeed which is supported by [11,25]. The Poynting vector describes power flow out of a lumped circuit both as radiation and current flow [34].…”

“…The instantaneous theories are less suitable to energy measurement since they do not characterize active/reactive loads fully and accurately [11,12,24,25]. These theories are suitable for power conditioning [19] with instantaneous response time at the sampling rate, and do not require storage components but rather only switching circuits [19].…”

“…These theories are suitable for power conditioning [19] with instantaneous response time at the sampling rate, and do not require storage components but rather only switching circuits [19]. On the other hand the periodic averaged theories attempt to insure correct energy measurement, and correct active/reactive load identification [11,12]. These theories are also applicable to active filtering and power conditioning with time response, of a single period [13].…”

“…The work in [10], and also [11][12][13][14] demonstrates research which suggests that the various theories should be regarded as different points of view on the same phenomena, with different optimization criteria of the active energy transmission loss.…”
