This paper presents the application of DSTATCOM in a distribution network with induction furnace load. Induction furnace is one of the common types of load used in industries like the steel industry. The problem with the induction furnace load is the generation of appreciable amount of harmonic distortion. This distortion results due to the design and operation of the induction furnace. This ha...

In this paper, we present an improved harmonic coder for the wideband. In an effort to improve spectrum modelling with harmonic representation, we include in the structure, a post error spectrum modelling that is essentially useful for noisy signals or mixed spectra of high pitch voices. The bit constrained error spectrum modelling procedure coupled with an efficient quantization of the harmoni...

Load flow analysis is widely used for finding voltage at various parts of a large, interconnected power system. The exponential increase in the use electronic devices and noticeable percentage integration renewable energy sources modern systems result occurrence non-sinusoidal voltages By reformation Newton-Raphson load method, few harmonic algorithms have been developed transmission systems. H...

This paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. The power filter integrates a passive power filter which is a RL low-pass filter placed in series with the load, and an active power filter which comprises an RL in series with an IGBT based voltage source converter. The filter is assumed...

The single-phase traction load has essentially an unbalance characteristic at the Point of Common Coupling (PCC), which injects harmonic into the utility grid. In this paper, the effect of harmonic distortion and unbalance loading are investigated simultaneously for electrical railway systems. Special traction transformers (i.e. single-phase, V/V, Wye-Delta, Scott, and Le Blanc) are used betwee...

During the last decade power system have been equipped with complex components such as Distribution Static Var Compensators (D-SVCs). These components have introduced new possibilities to control power systems, D-SVCs can almost continuously change the amount of reactive power from capacitor banks. The behavior of these new components is different from 'old' technologies since they contain powe...

Chapter 3 presents ANN based adaptive shunt passive filter, whose performance is found to be superior to fixed element shunt passive filter in harmonic and reactive compensation. However, the drawback is that it can provide only partial harmonic and reactive power compensation. Hence, an ANN based digital controller for active filter is developed. It compensates for the major portion of source ...

A multiphase harmonic load flow algorithm is developed based on backward/forward sweep to examine the effects of various factors on the neutral to earth voltage (NEV), including unsymmetrical system configuration, load unbalance and harmonic injection. The proposed algorithm composes fundamental frequency and harmonic frequencies power flows. The algorithm and the associated models are tested o...

With the introduction of more non-linear loads, e.g., compact fluorescent lamps, electric vehicles, photovoltaics, etc., the need to determine the harmonic impact of the residential load is rising, illustrated by the many studies performed on their harmonic impact. Traditionally, these studies are performed for a single new device and single penetration level, neglecting the harmonic interactio...
