The reduction of voltage fluctuation's effects which is born in agricultural irrigation in Kiziltepe region with the use of drive system in induction motors

Irrigation network of GAP's range of application in which high rate of Turkey's agricultural land exists is insufficient. Therefore irrigation process is made in facilities that farmers have established with their own possibilities and , groundwater from deep wells is removed to earth with a big powerful asynchronous motors. Large powerful induction motors are used in these irrigation systems. Induction motors in electric power systems is one of the sources which affects power quality for the transmission and distribution networks, especially mains voltage in a high degree. Drive systems become widespread in order to reduce the effects of induction motors on the electrical quality. In recent years, many control methods have been developed in the drive system in order to serve this purpose in the best way. It is intended to have more efficient system and better quality of the electrical system by using variable speed drives in variable torque loads such as ventilation and pumps. In this study Kızıltepe region was selected as the working zone . The region's electricity grid and power quality problems were examined. By handling a irrigation system in region, induction motor -pump group which was used in facilities was modelled in MATLAB / Simulink and simulation studies were backed. In simulation studies, the effects of deterioration network voltage were investigated on the performance of induction motors. Voltage measurement results which were taken from the centres of the transformer in Kızıltepe region were used in simulations. Motor output parameters were examined by connecting with motor - pump group and different types of corrupt directly to the mains voltage variable speed drives (VSD) and the results are presented. . Depending on the results, precautions which can be taken in the asynchronous motor systems to reduce the wave in mains voltage were discussed.
