Abstract:
In recent years, with the development of technology, significant
progress has been experienced in the industrial field. Although these
technological developments provide great convenience in industrial areas, they
cause serious increases in the amount of energy consumed. Variable frequency drives are used in order to reduce
the amount of energy consumed in industrial facilities.
Although variable frequency drives are frequently
used, they are extremely sensitive to power quality events. For this reason,
the uninterrupted and continuous power supplied to the devices will increase
energy efficiency along with the quality in the production process. In the
literature, uninterrupted and continuous energy is explained together with the
concept of power quality. The deterioration in power quality will adversely
affect the production process in industrial facilities. Power quality problems
can be basically defined as disturbances in current and voltage. One of the most common power quality problems is
voltage sags. Variable frequency drives are adversely affected by these voltage
sags. In this thesis,
power quality problems occurring in an industrial facility and the effects of
these problems on the facility are examined. By evaluating the existing methods in the literature,
an active front end and energy storage based method, which is a hybrid method,
has been developed and proposed. This proposed study is modeled with MATLAB/Simulink
simulation program on variable frequency drives and applied in facility. As a
result of this proposed study, all voltage sags that occur are prevented. This method has been found to be 44% more
cost-effective than conventional methods.
