The Power Quality Centre at the University of Wollongong has been in operation since 1996 and has made progress in many areas of power quality, with power system harmonics being a major focus. The paper will discuss some important issues in harmonics still needing to be resolved, including (i) the economic case for harmonic control, (ii) the setting of appropriate voltage limits, (iii) measurem...

The author shows that the use of high-resolution spectrum estimation methods instead of Fourier-based techniques can improve the accuracy of measurement of spectral parameters of distorted waveforms encountered in power systems, in particular the estimation of the power quality indices (such as inter/harmonic groups and subgroups). The comparison of the frequency and amplitude estimation error,...

Power quality is one of major concerns in the present era. It has become important, especially, with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply. Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency that results in a failure or mis-operation of end user equipments. One of the major prob...

Industries having poor power factor face the problem of reduced power quality and increased electricity charges. To improve the power factor, capacitor banks of appropriate KVAR ratings are to be placed. In this paper the inductive loads in a sugar mill are investigated and suitable power factor improvement capacitors are recommended. The effect of low power factor on distribution losses and KV...

This paper concerns the problem of proper evaluation of power quality in naval networks. Two aspects of the problem have been addressed. Firstly, the appropriate choice of power quality parameters for the aim has been discussed. Secondly, the methods of their estimation especially concerning aggregating of measurement intervals have been discussed. These considerations will be based on the basi...

With the electric industry undergoing change, increased attention is being focused on power supply reliability and power quality. Power providers and users alike are concerned about reliable power, whether the focus is on interruptions and disturbances or extended outages. Monitoring can provide information about power flow and demand and help to identify the cause of power system disturbances....

This paper reports on new efforts in the modernization of the basic undergraduate courses and a graduate curriculum in electric power engineering. The main focus of the paper is the modernization of the way power engineering is portrayed to students. The motivation is the recognition of the new deregulated and restructured environment in power engineering and the broadening of the area in gener...

A scalable multi-agent paradigm is presented for control of distributed energy resources to achieve higher reliability, higher power quality, and more efficient (optimum) power generation and consumption A dynamic hybrid multi-agent system is proposed in this paper as a means to achieve scalability for control of a large network of power generation, transmission, load, and compensation sources....
