Synchronous Machine on Infinite Bus Bars: A definite procedure has to be followed in connecting a Synchronous Machine on Infinite Bus Bars which for the present purpose will be assumed to be infinite. Infinite bus-bars…

Armature Reaction in Synchronous Generator: The Armature Reaction in Synchronous Generator is dependent on the power factor at which the machine is operating and upon the operating mode generating/motoring. For simplicity of explanation, it will…

Armature Reaction in Synchronous Motor: The Simple circuit model of the synchronous machine was obtained in Sec. 8.3 by making the assumption that the magnetic circuit of the machine is linear. However, it is known…

Determination of the Synchronous Reactance | Open Circuit and Short Circuit test of Synchronous Machine: Determination of the Synchronous Reactance - With the assumption of a linear magnetic circuit, the circuit model (per phase) of…

Equivalent Circuit of Synchronous Motor: By assuming linearity of the magnetic circuit, it is possible to obtain simple Equivalent Circuit of Synchronous Motor. The validity of this assumption stems from the fact that air-gap is…

Voltage Regulation of Synchronous Generator: The Voltage Regulation of Synchronous Generator is defined on lines similar to that of a transformer. Consider the generator supplying full-load current at a specified power factor and rated terminal…

Generating Mode and Motoring Mode of Synchronous Machine: Generating Mode and Motoring Mode of Synchronous Machine is derived by a realistic synchronous machine will have resistance ra and leakage reactance xl per armature phase which…

Construction of Cylindrical Rotor Synchronous Machine: As stated earlier the Cylindrical Rotor Synchronous Machine offers constant permeance to mmf waves irrespective of the mechanical position of the rotor and is, therefore, simpler to model. Figure…
