(STEADY STATE MODEL AND PERFORMANCE) of SINGLE-PHASE INDUCTION GENERATORS OF EQUIVALENT CIRCUIT - Thesis Example The single phase induction generator has become one of the devices in consideration to achieve this goal it was explored with a view of bringing cost effective small power generator acceptable to the users. The induction generator is considered more advantageous as compared to the synchronous generator. It has the following advantages: rugged in construction, low maintenance and operational cost, self protection against fault, good dynamic fault, capable of generating power at varying speed and do not need brushes and commentators. The self excited induction motor uses turbines (steam, water and wind) as the prime mover to produce power. The prime mover rotates the rotor windings thereby causing it to cut the magnetic flux induced by the excitation windings connected to an external power source. The end of stator main windings is taken and connected to the required load. The induction generator only operates when there is the slip that is the rotor should rotate at a speed greater th an synchronous speed of the stator magnetic flux. The self excited single phase induction generator structure consist of the rotor (rotor windings) and stator (has both the main and exciting windings).The rotor shaft is connected to the prime mover while one end terminals of stator main windings has provision for load connection. The main winding has a series connected capacitor that regulates voltage output and provide power of the connected load. With no load connected to the main winding the generator after self-excitation run at desired speed and produces certain no-load voltage which can only be changed by varying the self-excitation capacitor accordingly. Connection of the load leads to drastic drop of terminal voltage due to increased reactive power VAR. To maintain the terminal voltage, capacitor value in the series with the load is increased to counter for the
