Renewable energy plays a significant part in the power generation revolution in line with the future smart grid focus. In Malaysia, one of the largest, clean and green energy produced is the solar PV energy. With obvious increase of penetration by renewable energies especially solar energy, in years to come the grid system is capable to self-sustain as micro grid without heavily depending from fossil...
With the increase penetration of renewable energy sources such as solar being connected to the utility grid, the use of power converters plays a major role in ensuring maximum power delivered with high efficiency. Though, the usage of power converters indirectly leads to the rise of harmonic content in the distributed system with its switching mechanism for power conversion. Filters are widely used...
This paper presents a power quality event source directivity detection based on V-I scatter graph. The proposed method is capable to detect both voltage sag and transient power quality event source direction in term of upstream and downstream based on one bus measurement. The V-I scatter graph are plotted based on the RMS voltage and current magnitude at the same instant of time sample onto the voltage...
Locating faults in a power network has been a common chore for utility personnel. However, with the increasing demand in consumer expectations nowadays, fault location time needs to be shortened so that supply can be restored as soon as possible. Considerable amount of time can be saved if an automated mechanism is available to direct the repair crew to the region of fault. Transmission system has...
A real time power quality event detection and logging system using continuous wavelet transform is presented in this paper. A virtual instrument concept is adopted to implement the continuous wavelet transform in real time. The measurement hardware consists of data acquisition module with USB interface and the wavelet event detection algorithm was developed using MATLAB with graphical user interface...
