Instructions and Help about microelettrica scientifica mg30 i

Let's start by reviewing the theory of operation of a synchronous AC generator presented earlier in this course prior to our discussion of generator protection when current flows through conductor a magnetic field is formed the higher the current flow the stronger the magnetic field an electromagnet can be formed by winding the conductor around the materials such as iron which has a low permeability or resistance to the flow of magnetic lines of flux depending on the direction of current flow one end of the iron core will be a North Pole while the other is a South Pole the magnetic lines of flux will leave the North Poland flow to the South Pole returning to the North Pole through thereon core when magnetic lines of flux cut through a conductor a voltage is induced in the conductor the magnitude of the voltage is proportional to both the strength of the magnetic field and the speed with which the magnetic field cuts through the conductor asingle-phase generator is composed of two major components the exciter and testator the exciter is an electromagnet that rotates about its axis as shown testator is constructed from two electromagnets or poles wired in series to a load and as the name implies remain stationary as the exciter rotates its magnetic field cuts through the windings the stator poles inducing a voltage and hence current which will flow through the attached load as shown large utility class generators producethree-phase alternating current and sewer single-phase generator is modified with the addition of two more pole pairs the poles would be positioned such that the pole pairs are directly opposite each other and planes running through any two pairs of poles will intersect Alan angle of 120 degrees this arrangement of poles forms the stator of a two polethree-phase generator it is called a two pole generator because the stator has two electron magnetic poles per phase onside of each pair of windings disconnected together while the other sides connected to our three-phase load if we plot a graph of the voltage which appears across each of our load resistors against time as the exciter rotates through one revolution we will see the waveform shown as the exciter rotates the voltage induced in each hereof stator windings will be displaced by120 electrical degrees from the other two waveforms corresponding to the physical annular position of the stator windings the resulting output is the desired three sine waves of equal amplitude but with a 120 degree phase shift between them as shown there are many sources of generation for electrical power hydroelectric nuclear natural gas and fossil fuels just to mention a few the mechanical systems used to convert these sources of energy into electrical power vary greatly in both physical construction and in mechanical limitations for example hydraulic turbine is designed to withstand over speeds that occur during startup and shutdown while on the other hand a steam turbine with base speeds in the...
