Photovoltaics have more attraction day by due to increasing technologies and decreasing prices. However, in practice, the applicants encounter fundamental problems such as shadow effects degradation. Due these problems, amount of produced annual electricity decreases considerably. Moreover, it is not easy understand if company's PV satisfies requirements or appropriate for application. In order...

Modern electrical machines employed in transportation applications are required to provide high performance terms of power (and torque) density. At the same time, being these safety-critical, a significant level reliability and/or fault tolerance is expected. Among all factors which can compromise motors reliability, partial discharges (PDs) inception one most crucial, particular for low voltag...

earth pressure balance tunnel boring machines (epb-tbms) are favorably applied in urban tunneling projects. despite their numerous advantages, considerable delays and high maintenance cost are the main disadvantages these machines suffer from. reliability, availability, and maintainability (ram) analysis is a practical technique that uses failure and repair dataset obtained over a reasonable ti...

In 2001, Power Electronics and Electric Machines program was fully developed in electrical and computer engineering department at Cleveland State University. To support newly developed curriculum, state of the art Power Electronics and Electric Machines Laboratory has been established. This effort has been supported by National Science Foundation (award # 0410912), Nasa Glen Research Center and...

Simulations are widely used in the study of both electrical machines and drives. In the literature, several simulation approaches can be found which can be also applied in the study of the switched reluctance motors (SRMs). The on-line SRM simulation tool developed by the authors and presented in this paper proved to be very useful both in checking the design of the motor, but also in setting u...

This paper presents a new genetic algorithm with tabu list and sharing scheme for optimizing the design of electrical machines. The design problem was formulated as a multimodal function optimization problem. All the obtained solutions are divided into clusters before being judged by a trained neural network to decide which solution is optimal. From the results of examples, as well as compariso...

Cloud computing is a result of the continuing progress made in the areas of hardware, technologies related to the Internet, distributed computing and automated management. The Increasing demand has led to an increase in services resulting in the establishment of large-scale computing and data centers, in addition to high operating costs and huge amounts of electrical power consumption. Insuffic...

The Winding Function Approach has been used since 1965 to describe the inductance behavior of small air-gap electrical machines, and several works have contributed its formulation in presence mechanical faults, such as eccentricity, leading Modified (MWFA). In order use MWFA, an integral over a full rotation period needs be computed. Nevertheless, this typically requires performance numerical i...

Calculations of iron losses in the electrical machines are normally based on experimental characteristics of core material used in the machines. These methods with simplified machine analysis approximations are usually employed for calculation of total iron losses of electrical machines whilst local flux densities and corresponding local iron losses especially when designing of the machine and ...
