Electrical Generator

_ Alternating Current and Direct Current Generator Pedro Portela, João Sepúlveda, João Sena Esteves Department of Industrial Electronic University of Minho, Campus of Azurém, 4800-058 Guimarães, Portugal delfimpedrosa@gmail.com, sena@dei.uminho.pt Abstract. Spinning a wire loop within a uniform magnetic field in a convenient fashion induces a voltage between the loop terminals. This effect can be used to build an electric power generator, such as the one described in this paper. A...

Calculating Generator Reactances

Calculating generator reactancesPower topic #6008 | Technical information from Cummins Power Generation Calculating generator reactances > White paper By Timothy A. Loehlein, Technical Specialist-Electrical Generator reactances are used for two distinctly different purposes. One use is to calculate the flow of symmetrical short circuit current in coordination studies. A second use for generator reactances are in specifications that limit the sub-transient reactance to 12% or less in order...

Synchronous Generators

DISCUSSION 8 REFERENCE 10 INTRODUCTION Synchronous generators or alternators are synchronous machines used to convert mechanical power to ac electric power. Nowadays, an isolated synchronous generator supplying its own load independently of other generators is very rare. Such a situation is found in only a few out-of-the-way applications such as emergency generators. For all usual generator applications, there is more than one generator operating in parallel to supply the power demanded by the...

How an electric generator works

ELECTRIC GENERATOR WORKS Electrical generators by definition are devices that convert mechanical energy into electric energy. The mechanical energy in turn is produced from chemical or nuclear energy in various types of fuel, or obtained from renewable sources such as wind or falling water.  Steam turbines, internal-combustion engines, gas combustion turbines, electric motors, water and wind turbines are the common methods to supply the mechanical energy for such devices. Generators are made...

Generators: Electric Power and Ashe Members

is conducting a Field Review of its proposed addition to standard EC.7.40 on the inspection, testing and maintenance of emergency power systems. JCAHO proposes to add a new Element of Performance (EP) requiring annual testing of each emergency generator for four continuous hours, under load. ASHE members are encouraged to take full advantage of this opportunity to: • Provide your input on the actual need for this new requirement, • Comment if this requirement will assure greater reliability...

Seven Possible Generator Arrangements

7 Possible generator arrangements This section discusses various generator arrangements and their suitability for use in the conversion of a traditional windmill. The generator arrangement may include a speed-increasing gearbox or belt-drive and/or a power electronic frequency converter. See also the Appendix: Background information on induction generators. 7.1 Fixed-speed induction generator Many modern wind turbines (especially those manufactured during the 1990s) use a four-pole induction generator...

Design of a New Gas Turbine-Generator System

1. INTRODUCTION : Gas Turbine-Generator system has proximity to zero level due to absence of condenser. Therefore, Generator should have Terminal Bushings at the top of the Stator Frame. This avoids digging of tunnel / trench for routing Bus Duct and also avoids accumulation of gases from safety point of view. It was decided to develop a module THRI 108/44 for application with Gas Turbine. 2. DESIGN CHALLENGES : Since, bar type design of THRI 108/44 module for GTG application is not...
