Abstract

In this study, frequency scan analysis and harmonic resonance modal analysis are two
techniques that have been chosen to analyse the present of resonance in a network. The
presence of resonance is the factor that contributes to the amplification of harmonic
which exist along with the current from non-linear load. Harmonic that occurs contributes
to several negative effects to the power system and has potential to cause the equipment
to damage. Universiti Teknologi PETRONAS (UTP) new building network, or to be
more specific, the network at new academic buildings is an interesting place to conduct
this study. This is because in UTP there are various types of electrical machines, high
voltage machines and high technology computers and equipments especially in block
5,17 and 22; that may contribute to harmonic. The whole UTP network is first simplified
and the cable is present in pi impedance form. After that, the power flow study of the
network is conducted using a MATLAB Simulink. The potential resonance from UTP
network is analysed using the two techniques that have been mentioned above. The
techniques are also run using MATLAB. The measurement of harmonic current and
voltage at the respective buildings are then performed for six (6) days at the sub switch
board (SSB) of the three blocks that have been chosen as the case studies. The data
obtained from the data logging are compared with the data obtained using the two
techniques mentioned earlier. The expected results are high harmonics is present at the
harmonic frequencies which are high in resonance.
