The important feature of presented scheme is leading and high power factor with smooth control. In this paper, the […]

Investigations for Quasi-Z Source Based Cascaded H-bridge Inverter With Unequal Input Voltages

Abstract Owing to the advantages of the distributed generators and hybrid energy system, the inverter with more than one dc source is now increasingly investigated. This paper presents a control scheme for single phase quasi Z source inverter (qZSI) network based on Cascaded H-bridge five level based boost inverter using the Simple Boost Control (SBC). […]

Overview of Existing Electricity Tariff Structure & Residential Load Pattern in Maharashtra: A Case Study

Abstract Use of energy sensibly, based on the availability of Time of Day (ToD) tariff, is the most important tool in demand side management. ToD offers a variety of prices at different time intervals and generally remains same for all seasons. This paper presents an overview of electricity tariff structures, objectives of tariff policy, slab […]

Comparative Analysis of Power Loss using Different Modulation Techniques in Modular Multilevel Converter

Abstract The application of voltage source inverter in medium and high power application is increasing extremely. Multilevel converters reduces the height of voltage steps at converter output and thus also dv/dt and voltage harmonics. In high power applications high efficiency of converter is the most important aspect. Hence the power loss analysis has to be […]

Development of Micro Phasor Measurement Unit (µ-PMU) to Facilitate Synchrophor Learning at Undergraduate Level

Abstract Synchrophasor and Phasor measurement unit (PMU) technology has been widely deployed in electrical power transmission network for protection and state estimation. This technology has also been extended at distribution level mainly in Smartgrids and Microgrids. The increased applications of Synchrophasors had made it necessary to develop trained engineering graduates in the field. In this […]

Modelling and Speed Control of Permanent Magnet Brushless DC Motor using PID

Abstract Trapezoidal flux distributed Permanent Magnet Brushless DC motor (PM-BLDC) has several advantages as compared to conventional DC and AC motor such as high speed, low weight-to-power ratio, high speed, electronic control, and low maintenance. The PM-BLDC motor also known as electronically commutated motor. Day by day usage of PMBLDC motor is increasing, so it […]

Discrimination of Inrush and Fault Currents in Protection of Transformer using ANN-DWT Technique

Abstract The main objective of relay is to reduce the occurrence and duration of undesirable outages concerned to the power transformer. This can be achieved by avoiding false tripping and achieving a high operating speed relay. In order to achieve these objectives digital relays are employed which are based on various topologies and concepts, in […]
