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.
