In power distribution networks, nonlinear loads produce harmonic currents that can pass through other sensitive locations in the power system and eventually back to the source. Harmonic currents can produce a variety of effects that are harmful to a power system structure. Consequentially, the deployment of new cost and energy efficient passive, active and hybrid filtering techniques is importa...

Matrix converter is a single-stage converter which directly connects a three-phase voltage source to a three-phase load without dc-link components. Therefore, any harmonic distortion and imbalance in input voltage directly reflect to the output of the converter. Recently, many researchers have made an effort to cope with this problem. In this paper, under distorted input voltage conditions, beh...

Performance evaluation of an axial flux surface mounted permanent magnet (PM) field controlled TORUS type (FCT) disc machine is presented in this paper. This new machine is an axial flux configuration with true field weakening capability since the flux is controlled by the DC field winding rather than opposing the magnets. Structure and operating principles are summarized in the first section. ...

In distribution systems, sudden change in load draws non-sinusoidal currents and causes the load harmonics, excessive neutral currents creates disturbance and changes in Power factor. Static Synchronous Compensator (STATCOM) is used to provide reactive power to the transmission line. In this paper proposes with Fuzzy Logic Controller (FLC) to tune PI controller gain values under different opera...

This paper proposes an effective method for estimating the parameters of double-cage induction motors by using Artificial Bee Colony (ABC) algorithm. For this purpose the unknown parameters in the electrical model of asynchronous machine are calculated such that the sum of the square of differences between full load torques, starting torques, maximum torques, starting currents, full load curren...

In most arc fault circuit breakers, arc detection is accomplished through the signature analysis of remotely sensed branch currents, with high frequency spectral components being indicative of arcing. This paper presents an alternative approach based upon system identification. A model is assumed for the load on the distribution bus. This model is updated continuously by comparing measured volt...

This paper investigates the design,analysis and simulation of a Distribution-STATic COMpensator(D-STATCOM) for non-linear load Composite(harmonic and reactive power) compensation on a three phase bus network. Composite compensation is achieved by implementation of a p-q controller, which monitors the load current and injects equal amplitude and opposite phase compensation currents to neutralize...

In modern power system, the switching devices are generally used in combination with unbalanced reactive loads which produces current related Power Quality (PQ) problems by making source currents distorted and unbalanced. Usually a STATCOM is installed to support electricity networks that have a poor power factor and often poor voltage regulation. A Distribution Static Compensator (DSTATCOM) op...
