Every electrical circuit is a potential source of electrical interference, particularly when switching reactive loads. Most electrical interference is low level and has no noticeable effect on other branches of electrical equipment. Variable speed drives, however, are highly non-linear loads; input rectifiers produce a high level of harmonics that may affect the performance of other devices con...

The non-linearities in waveand slamming-induced rigid-body motions and structural responses of ships such as heave, pitch and vertical bending moments are consistently investigated based on a rational timedomain strip method (Xia, Wang and Jensen, 1998). A hydrodynamic model for predicting sectional green water force is also outlined for the investigation of the effect of green water loads on t...

In distribution system (DS), the majority of power consumption has been drawn in reactive loads. These loads are drawn in low power factor and therefore give rise to reactive power burden in the distribution system. So that DSTATCOM controller is used to compensate reactive power, correction of power factor and elimination of current harmonics. This paper presence the 7-Level Cascaded Hbridge I...

-As a result of the increasing use of electronic devices and other non-linear loads, the wave-forms of the electricity supply voltage are being distorted and inequalities are appearing between the phases. This deterioration is associated with problems of electromagnetic incompatibility and reductions in the efficiency of loads such as motors. This paper investigates the additional losses caused...

1. Abstract In the real world, structural systems may show nonlinear dynamic behavior. Linear static response structural optimization has been developed quite well by using linear static response analysis. Finite element analysis regarding the nonlinearities or dynamic effects has also been developed very well. However, conventional optimization methods considering the nonlinearities or dynamic...

Transformers are normally designed and built for use at rated frequency and perfect sinusoidal load current. A non-linear load on a transformer leads to harmonic power losses which cause increased operational costs and additional heating in power system components. It leads to higher losses, early fatigue of insulation, premature failure and reduction of the useful life of the transformer. To p...

Harmonic distortion has garnered a lot of interest in the recent past due to the high advent of the non-linear electronic loads. Moreover, newer technologies including distributed generation and electric vehicles are anticipated to be part of the distribution systems at a mass scale in the near future. This makes it of utmost importance to evaluate the existing power distribution systems and an...
