Electric Generators Handbook pdf

Ion Gheorghe Boldia (nacido el 7 de enero de 1945) es profesor emérito de la Universidad Politehnica Timisoara, Rumania. Ion Boldea ha introducido muchas novedades en tecnología de máquinas eléctricas para mejorar la productividad industrial, ahorrar energía y reducir la contaminación del aire. Desarrolló un factor de bondad óptimo para diseñar motores de inducción lineales de alta velocidad para abordar factores como las vibraciones mecánicas y la flexión. Presentó el Magnibus-01, un vehículo de prueba de levitación magnética de 4 toneladas con motores síncronos homopolares lineales para propulsión y levitación magnéticas integradas con guías pasivas. El concepto de flujo activo del Dr. Boldea es una fuerza unificadora para simplificar el control sin sensores de los accionamientos de motores de CA que se ha implementado en muchas aplicaciones industriales. Su trabajo en el control del vector de par se ha convertido en un estándar industrial para accionamientos de motores eléctricos.

Variable Speed Generators, the second of two volumes in the Electric Generators Handbook, provides extensive coverage of variable speed generators in distributed generation and renewable energy applications around the world. The book delves into the steady state, transients, control, and design of claw-pole-rotor synchronous, induction, permanent-magnet-(PM)-assisted synchronous, and switched reluctance starter alternators for electric hybrid vehicles. It discusses PM synchronous, transverse flux PM, and flux reversal PM generators for low-speed wind and hydro energy conversion. It also explores linear motion alternators for residential and spacecraft applications. Numerous design and control examples illustrate the exposition. Fully revised and updated to reflect the last decade’s worth of progress in the field, this Second Edition adds new sections that: Address the ride-through control of doubly fed induction generators under unbalanced voltage sags Consider the control of stand-alone doubly fed induction generators under unbalanced nonlinear loads Detail a stand-alone squirrel cage induction generator (SCIG) with AC output and a low-rating pulse-width modulated (PWM) converter Present a twin stator winding SCIG with 50 percent rating inverter and diode rectifier, and a dual stator winding induction generator with nested cage rotor Examine interior permanent magnet claw-pole-alternator systems for more vehicle braking energy recuperation, and high power factor Vernier PM generators Depict a PM-assisted reluctance synchronous motor/generator for an electric hybrid vehicle, and a double stator switched reluctance generator with segmented rotor Describe the grid to stand-alone transition motion-sensorless dual-inverter control of permanent magnet synchronous generators with asymmetrical grid voltage sags and harmonics filtering The promise of renewable, sustainable energy rests on our ability to design innovative power systems that are able to harness energy from a variety of sources. Variable Speed Generators, Second Edition supplies state-of-the-art tools necessary to design, validate, and deploy the right power generation technologies to fulfill tomorrow's complex energy needs.
