“…One of the methods to improve the Power Factor of three phase induction motor is through Power Factor Controller (PFC) with Programmable Logic Controller (PLC) in which the voltage to frequency ratio is maintained constant in order to obtain a maximum torque. To minimize the pseudo oscillation and harmonics, Zero voltage switching of static switches is allocated in the control algorithm [15]. In order to evaluate the performance characteristics of a designed three phase induction motor with written pole technology, a series of testing has been carried out.…”

“…Applications of PLC have been reported for monitoring control system of an induction motor [3,4]. PLC has been also used as a power factor controller for power factor improvement and to keep the voltage to frequency ratio of a three-phase IM, constant under all control conditions [5]. Also, a vector-oriented control scheme, for the regulation of voltage and current of threephase pulse width modulation inverter, which uses a complex programmable logic device (CPLD) [6], has been reported.…”

A laboratory setup of distributed drives system comprising a three-phase induction motor (IM) drive and a permanent magnet synchronous motor (PMSM) drive is modeled, designed, and developed for the monitoring and control of the individual drives. The integrated operation of IM and PMSM drives system has been analyzed under different operating conditions, and their performance has been monitored through supervisory control and data acquisition (SCADA) system. The necessary SCADA graphical user interface (GUI) has also been created for the display of drive parameters. The performances of IM and PMSM under parametric variations are predicted through sensitivity analysis. An integrated operation of the drives is demonstrated through experimental and simulation results.

“…There are a few papers published about the control of IMs with PLC. One of them is about power factor controller for a three-phase IM that utilizes a PLC to improve the power factor and to keep its voltage-to-frequency ratio constant over the entire control range [17]. The other paper deals with monitoring control system of the induction motor driven by an inverter and controlled by a PLC providing its high accuracy in speed regulation at constantspeed-variable-load operation [16].…”

Protection of an induction motor (IM) against possible problems, such as overvoltage, overcurrent, overload, overtemperature, and undervoltage, occurring in the course of its operation is very important, because it is used intensively in industry as an actuator. IMs can be protected using some components, such as timers, contactors, voltage, and current relays. This method is known as the classical method that is very basic and involves mechanical dynamic parts. Computer and programmable integrated circuit (PIC) based protection methods have eliminated most of the mechanical components. However, the computer-based protection method requires an analog-to-digital conversion (ADC) card, and the PIC-based protection method does not visualize the electrical parameters measured. In this study, for IMs, a new protection method based on a programmable logic controller (PLC) has been introduced. In this method, all contactors, timers, relays, and the conversion card are eliminated. Moreover, the voltages, the currents, the speed, and the temperature values of the motor, and the problems occurred in the system, are monitored and warning messages are shown on the computer screen. Experimental results show that the PLC-based protection method developed costs less, provides higher accuracy as well as safe and visual environment compared with the classical, the computer, and the PIC-based protection systems.
