Salient Pole Generator

Product Description

Description:

The Salient Pole Generator explores the principles andcharacteristics of salient pole generators. It contains everything needed forsalient pole generator experiments including resistive capacitive and inductiveload banks. The open and flexible design is ideal for lecturers to create theirown experiments, as well as student project work. To allow realisticinvestigations, the characteristics of the prime mover and generator aresimilar to industrial turbine and generator sets. The prime mover and generatorset is two coupled machines mounted on a common bedplate in the base of theconsole. Manual or automatic voltage regulation excitation controls theoutput voltage of the generator. When the generator is in overrun mode,resistors dissipate the reverse power. A vector drive controls the speed of theprime mover and allows investigations into load flow in positive and negativedirections. An integral shaft encoder allows load angle analysis. The user maysynchronise the generator output to the grid supply using a synchroscope. Theymay also use the set of three coloured lamps. The control and protectioncircuits work when the generator is unsynchronised and synchronised to themains electrical supply. When the generator is synchronised, the user canoperate a variable quadrature droop for reactive power regulation.
