Performing reactive power compensation of three-phase induction motor by using parallel active power filter

Abstract

Nowadays, the problem of power quality increases day by day. Harmonic current and reactive power are the important factors disturbing the power quality. The induction motors draw both harmonic current and reactive power from the grid. Reactive power and harmonic current lead to heat losses and decrease in the efficiency of the transmission lines. Passive and active filter applications have been used to solve these problems. There are some disadvantages of passive filters. Large physical dimensions and resonance with load can be shown as examples for these disadvantages. Therefore, the application areas of Active Power Filter (APF) are rapidly developing due to the fact that they can be applied together with harmonic and reactive power compensation as appropriate control methods. This paper proposes a MATLAB/Simulink simulation to perform power factor correction and reactive power compensation of three-phase induction motor by using three-phase Parallel Active Power Filter (PAPF). In order to generate PAPF’s reference currents the Sine Multiplication Technique (SMT) is used. Simulation studies are presented to be able to assess the performances under different motor operating conditions. The proposed hysteresis controller based PAPF filter makes the power factor up to 1 and the reactive power compensation of the three-phase induction motor.

Investigation of energy parameters of a compensated asynchronous motor in the mode of repeated short-term starts

“…Individual compensation of the reactive power of asynchronous motors under various engine operating modes, in particular, during start-up, can be carried out using a capacitor bank with thyristor-controlled stages [12]. Another technical solution aimed at reducing the consumption of reactive power by AM is the use of active power filters that are switched on in parallel with the AM [13]. In [14], it is proposed to apply individual compensation of reactive power of AM implemented by connecting a three-phase capacitor bank of constant capacity and a three-phase regulated reactor in parallel to the motor stator winding.…”

Paralel Aktif Güç Filtresi Kullanarak Asenkron Motorun Reaktif Güç Kompanzasyonun PSCAD ile Modellenmesi

“…Şebekeden talep ettikleri reaktif güçler bazen büyük boyutlara çıkabilmektedir. Bundan dolayı ağır saniyeye sahip birçok ülkede üretilen enerjinin önemli bir yüzdesi üç fazlı asenkron motorlar tarafından tüketilmektedir [6]. Paralel aktif güç filtresi ile beraber kullanıldığında ise ASM'nin talep ettiği reaktif güç PAGF tarafından karşılanır.…”
