MOTOR STARTING STUDIES IN ELECTRICAL DISTRIBUTION NETWORK SYSTEM

Application of motor has been used widely in industry as it is now become very
essential for an industry through out these years. Various type and size of motors are
used to serve different type of purposes. An electrical power network distribution
system has to be designed in such a way that it can sustain the power required by
these motor, specifically HV motor. During starting process, a HV motor requires a
large amount of reactive power and drags generally six times its full load current in
order to magnetize the core. This tremendous demand normally will leave an effect
in an electrical distribution network if it is not properly designed and reduce motor
starting performance itself. The objective of this project is mainly to analyze a given
electrical distribution network system capability of handling motor demand on power
consumption during its starting process and come out with recommendations for the
network. In this project student will be doing an analysis on the network performance
by doing load flow studies and recommend a strategic planning for motor starting
process to suit the network capability. PETRONAS Penapisan (Melaka) Sdn. Bhd.
has been chosen as a network model to perform this study. There are three major
steps involved in performing this project. In early stage, load flow is required to be
performed in order to analyze the network condition prior to motor starting process.
At the second stage, a time domain simulation was performed. From here, the effect
of motor load on the system can be seen. At the end of the stage, few suggestions on
improvement will be developed as to enhance the performance of motor starting in
the network. With help from the experts and continuous hard work, hopefully this
project will be able to benefit the student in acquiring knowledge and generally to the
electrical power distribution network in enhancing the network performance.
