Software Implementation of Power Quality Standards

In recent years, equipment and network standards have been increasing in both number and complexity. Two standards that will soon be introduced to Australia are the MV and HV standards for assessing distorting and fluctuating loads, AS/NZS 61000.3.6 and AS/NZS 61000.3.7, respectively. Utility engineers, being under increasing time constraints, are turning more and more to software to quickly solve problems. This paper describes the methodology used to implement the above standards in Microsoft Excel in order to assist utility engineers to readily apply these standards in practical situations. The assumptions and simplifications used in this implementation are described.
