This paper represents the simulation of Shunt Active Power Filter(SAPF) based on p-q theory and using hysteresis current control to obtain the gating signals for three phase ac-dc converter. The proposed active power filter is employed to reduce the current Total Harmonic Distortion (THD) drawn by the non-linear load and compensate the reactive power. The PI controller is employed to reduce the...

A study on plug-in electric vehicle (PEV) charging load and its impacts on distribution transformers loss-of-life, is presented in this paper. The assessment is based on residential PEV battery charging. As the exact forecasting of the charging load is not possible, the method for predicting the electric vehicle (EV) charging load is stochastically formulated. With the help of the stochastic mo...

In this paper, a high-efficiency and compact AlGaN/GaN heterojunction field-effect transistor (HFET) power amplifier integrated with a microstrip antenna at 7.25 GHz is presented for RF front-end circuit applications. A microstrip circular sector antenna is employed as both a radiator and frequency-dependent output load. Higher order harmonics from the HFET in nonlinear operation are reactively...

Abstract— The active power filters eliminates the harmonic distortion caused by non-linear loads and improves the filtering efficiency performance when compared with the passive filters. This paper inspects about the analysis and simulation of a three phase four wire shunt active power f ilter under unbalanced and distorted load conditions. Current harmonic compensation is achieved by the imple...

In the present article, the effects of a non-linear load under balanced conditions on the rating of a transformer are analysed. Non-linear loads are related to temperature increases in a transformer, which lead to deterioration and reduction of lifetime. Due to the unwanted effects of harmonic components in non-linear loads, the load connected to the transformer should be reduced. In other word...

This paper describes the simulation model and the harmonics analysis of multi level inverters fed RL load and induction motor load. The SEIG fed Hbridge multi level inverter (MLI) for variable speed wind energy conversion systems are considered for various stand alone applications. In this paper, the SEIG fed cascaded five levels inverter for induction motor load systems are clearly explained w...

Electric locomotive is a kind of high power rectifier load, and its load characteristics will have a significant impact to safe, stable and economic operation of power system. This paper mainly analyses load characteristics of harmonic and reactive power for electric locomotive. Simulation model of electric locomotive is set up based on time trigger; it is so better conform to the dynamic chara...
