Review of Variable Speed Drive Technology By
نویسنده
چکیده
Variable speed drive technology has advanced dramatically in the last 10 years with the advent of new power devices and magnetic materials. This has given rise to substantial confusion by users and specifiers of variable speed drive equipment. Add to that the difficulty in evaluating efficiency and power factor and the subject of drive selection becomes a daunting task indeed. There is no single type of drive system which is perfect for all applications, therefore the purchaser must choose the most appropriate system for the job to be done. This paper will identify the drive types available in the industrial marketplace in integral horsepower sizes from 1 to 500 hp which covers the greatest majority of general industrial applications. Various characteristics of each type will be described including performance, size, ease of application, performance, maintenance, efficiency, power factor, and cost. Finally, comparisons will be made by type as to relative advantages and disadvantages since each type will be better suited for some types of applications than others.

Review in Transverse Flux Permanent Magnet Generator Design
Recently, Transverse Flux Permanent Magnet Generators (TFPMGs) have been proposed as a possible generator in direct drive variable speed wind turbines due to their unique merits. Generally, the quality of output power in these systems is lower than multi stage fixed speed systems, because of removing the gears, so it’s important to design these kinds of generators with low ripple and lowe...
متن کاملModern Topology& Thermal Analysis of Drive for Variable Speed Pumped Storage Power Plant
Given the significant power generation and consumption of variable-speed pumped storage power plants (VSPSPs), it is crucial to enhance drive methods and decrease drive losses, thereby increasing productivity. This paper proposes the topology for VSPSP drivers with two level voltage source converters (2LVSC) with 6+1 converters. Hydraulic and electrical VSPSP models are presented, following whi...

متن کاملA Novel MRAS Based Estimator for Speed-Sensorless Induction Motor Drive
In this paper, a novel stator current based Model Reference Adaptive System (MRAS) estimator for speed estimation in the speed-sensorless vector controlled induction motor drives is presented. In the proposed MRAS estimator, measured stator current of the induction motor is considered as a reference model. The estimated stator current is produced in an adjustable model to compare with the measu...
