| Summary: | 碩士 === 國立雲林科技大學 === 電機工程系碩士班 === 100 === This thesis presents a novel control algorithm that uses two Static Var
Compensators (SVCs) to balance a three-phase induction motor with Steinmetz
connection. To improve the unbalanced operation characteristics of the three-phase
induction motor supplied by a single-phase source, the author analyses the steady-state
sequence equivalent circuits of the motor connected in Steinmetz circuit and finds out
the balanced condition, which can be searched by the proposed algorithm. Two sets of
SVCs are used to achieve the balanced condition. Finally, simulation by Matlab-
Simulink is carried out to compare between simulated and analysis results. In addition,
the circuit scheme and its usefulness are observed by checking the motor operation
characteristics when working on different conditions like changing the motor
parameters or varying the values of the SVC components. It has been confirmed that the
circuit scheme will run below the current harmonic standards.
