“…However, the voltage harmonic deduced form this measurements need to be either calibrated or need to be recorded using the harmonic measurement infrastructure for transmission system [22]. In [23], a harmonic measurement devices (HMDs) are placed in a power system to identify the multiple harmonic sources and their harmonic injection levels. However, this is only relevant for a small interconnected transmission system [23,24].…”

A harmonic source diagnostic analytic is vital to identify the root causes and type of harmonic source in power system. This paper introduces a verification of periodogram technique to diagnose harmonic sources by using logistic regression classifier. A periodogram gives a correct and accurate classification of harmonic signals. Signature recognition pattern is used to distinguish the harmonic sources accurately by obtaining the distribution of harmonic and interharmonic components and the harmonic contribution changes. This is achieved by using the significant signature recognition of harmonic producing load obtained from the harmonic contribution changes. To verify the performance of the propose method, a logistic regression classifier will analyse the result and give the accuracy and positive rate percentage of the propose method. The adequacy of the proposed methodology is tested and verified on distribution system for several rectifier and inverter-based loads.

“…Various topologies of voltage source multilevel inverter have been proposed and the main ones are cascade H-bridge inverter, neutral-point-clamped and capacitor-clamped inverter [1], [2], [3], [4]. For conventional multilevel drives, one end of machine stator windings are star or delta connected while the other end is connected to those multilevel inverters in a configuration known as single-sided supply.…”

In this paper, a new control strategy for Direct Torque Control (DTC) of dual two-level VSI fed 3-phase induction motor drive in an open end winding configuration is presented. The drive can be operated in dual mode; open-end winding or conventional single-sided supply configuration; based on the condition of the motor speed. A block of Optimum Status Detection & Mode Selector (OSD & MS) is introduced to the original structure of the DTC in order to analyze the motor speed condition and also to monitor the torque operating condition. Based on the information from the block, a new lookup table is devised for selecting of the most optimum voltage vectors. Since the open-end winding providing greater numbers of voltage vector, it's have the capability to minimize torque ripple. A simulation has been conducted using MATLAB/Simulink in order to achieve the results.
