New effective power terms and right-angled triangle (RAT) power theory

Abstract

This article presents two new electrical power terms called effective active (P ef ) power term and effective reactive (Q ef ) power term. These two terms, can approve the orthogonality relationship between fundamental and distorted components.At the same time, these terms are necessary to complete the form of the right-angled power triangle which is compulsory condition to calculate the total apparent (St) in the non-sinusoidal systems.This paper also, offers a new definition for the total apparent power St or can be called effective apparent power (S ef ) in nonsinusoidal situation in order to avoid the misconception of the old definitions. Moreover, it shows a new power diagram represents all power components in one diagram consists of six right-angled triangles called the right-angled triangle (RAT) diagram.

Survey on time‐domain power theories and their applications for renewable energy integration in smart‐grids

“…Three relevant papers were published most recently [82][83][84]. In [82] the authors present a new power theory called 'right-angled triangle power theory.'…”

“…Three relevant papers were published most recently [82–84]. In [82] the authors present a new power theory called ‘right‐angled triangle power theory.’ They have rejected the Budeanu's power theory and defined the power components in a two‐dimensional diagram without the need for a standard three‐dimensional coordination system used before in Budeanu's theory. They also proved the ability to apply the orthogonality law on all power components in non‐sinusoidal systems.…”

Reactive power compensation considering high harmonics generation from internal and external nonlinear load

“…The term of «reactive power» is used when calculating linear electric load networks. However, electric technical complexes at modern enterprises have most loads presented by nonlinear receivers [3][4][5]. That is why the relevant legislation in many countries does not fix rates, discounts and additional charges to pay for reactive power, leaving it for electricity supplies agreements between parties [6][7][8].…”
