| Abstract |
The paper describes the conception of an intelligent soft starter for an induction motor (IM) on the base of thyristor direct converters and fuzzy logic control (FLC). The necessary conditions to be realized for soft starting process are reported and general algorithms of thyristor converter control are suggested. It is shown that in accordance with combined control (voltage/frequency control) at the multi step mode of starting under electromagnetic and electromechanical transients the proper choice of thyristor triggering algorithms is a complicated procedure. To overcome that problem the FLC for thyristor soft starter (TSS) is implemented and the system TSS-IM is investigated. The paper consists of three parts: classification and analysis on the base of spiral vector theory; transient phenomena in IM under starting process; optimal starters design with fuzzy logic control. |
