A comparative study of vibration and acoustic noise reductions via electronic switching controls for switched reluctance motor (SRM) is presented. First, studies concerning the acoustic noise and vibration sources, their effects and the existing mitigation approaches are given. Then five switching control approaches, which belong to the magnetic and electronic remedies, are proposed and applied...

The three-phase Shunt hybrid APF topology for harmonic mitigation in low and medium voltage power distribution systems consists of a VSI based three phase shunt active filter (SAF) and tuned passive filters (TPF) connected in parallel with the load. This chapter discusses the modelling of shunt active filter and design of filter interfacing inductor, DC bus capacitor, tuned passive filters. It ...

Flashover of polluted insulators in contaminated areas is one of the most important factors influencing the operation of transmission and distribution lines and finally line outages. Therefore, it is essential to prevent and detect flashover in the insulators. Hence, utilizing the insulator status monitoring systems and predicting their functions have absorbed a lot of attention over the recent...

In this paper analysis of two different cases is being compared for the presence of harmonics at manufacturing plant. Case 1, is a normal system configuration duly interfaced with CNC, AC servo drives, Spindle drive along with adaptive and in-process gauging system, High voltage Module, Isolation transformer and switchgear items and in case 2 additionally part compensated filter is added to red...

Due to environmental conditions, the wind power generation is fluctuating in nature. This affects the electrical network interconnected with these systems. When the wind power generators are connected to the nonlinear loads, there is distortion in the waveform. These distortions should be within limits according to national and international guidelines framed for power quality. This paper prese...

A new topology of unified power quality conditioner (UPQC) is proposed for different power quality (PQ) improvement in a three-phase four-wire (3P-4W) distribution system. For neutral current mitigation, a star-hexagon transformer is connected in shunt near the load along with three-leg voltage source inverters (VSIs) based UPQC. For the mitigation of source neutral current, the uses of passive...

In this study, we mitigated the harmonic voltage in a power system that contained roughing mill (RM) and finishing (FM) motor drives. AC/DC converter type RM drive is non-linear, large-capacity varying load adversely affects quality, e.g., flicker, distortion, etc. The drop can be compensated within certain limit by using proper capacity of capacitor bank. addition, distortion controlled as per...
