In this paper a variable speed generating unit is considered, equipped with permanent magnet generator. The system analysis involves appropriate models for the generator, the static converter and the grid. Moreover, an asynchronous generator mounted on the same rotor with dump loads ensures braking actions and management of the active power produced. The modelling of the generator and power ele...

This paper describes the development of a permanent magnet generator for small scale wind turbines. The generator has been designed for ease of manufacture so that it can be made by small mechanical engineering companies with limited electrical engineering knowledge. The generator has also been designed to have no cogging torque so that it can be used with all horizontal and vertical axis turbi...

This paper presents an analysis and simulation of a Wind Turbine Generator (WTG) driving a low speed Permanent Magnet Synchronous Generator (PMSG). The results of the tests are obtained by using the PSIM computer simulation program. The voltage source PWM inverter is used to interface the system with the electrical utility that is simulated in this paper as a resistive-inductive load.

In this paper, a comprehensive parametric analysis for an axial-flux permanent magnet synchronous generator (AFPMSG), designed to operate in a small-scale wind-power applications, is presented, and the condition for maximum efficiency, minimum weight and minimum cost is deduced. Then a Computer-Aided Design (CAD) procedure based on the results of parametric study is proposed. Matching between t...

Solutions Efficient operation of the gas turbine imposes the demand for very high rotational speed of the generator 240,000 rpm. The permanent magnet machine has been chosen as the generator type since this technology is the most promising for high-speed machines: it offers high efficiency and very high power density at low volumes. A high-frequency power converter is required to enable bi-dire...

The paper presents characteristics of a permanent magnet synchronous machine designed for micro-hybrid electric vehicle operation. Appropriate design of interior permanent magnet machine with 36 stator slots and 8 stator poles for operation in motor and generator operation mode was investigated. Finite element analysis is employed in order to determine the machine performance. Streszczenie. W a...
