This paper introduces a method to monitor power quality in a large 33 kV distribution network with minimal power quality recorders. This is achieved by using an intelligent driven application which is pseudo-measurement based, to approximate the bus voltages and currents at various busses in the network. Bus impedance matrix is manipulated by rewriting the node-voltage equations for an n-bus power...
This paper describes a novel approach to monitor power quality in a large 33 kV distribution network with minimal power quality recorders. This is achieved by using an intelligent driven application which is pseudo-measurement based, to approximate the bus voltages and currents at various busses in the network. Bus impedance matrix is manipulated by rewriting the node-voltage equations for an n-bus...
Online partial discharge (PD) detection and location systems for medium-voltage (MV) cables have been developed over the past years and are currently introduced by utilities on an increasingly large scale. This paper addresses a few of the new challenges related to the integration of these systems in various cable networks. The effect of ring-main-units (RMUs) and substations on the propagation of...
Nowadays power quality, especially voltage quality becomes more and more important for utilities, manufacturers and customers as well as for the regulatory authorities. Therefore a growing number of voltage quality monitoring campaigns with continuously increasing measurement times, considerably longer than one week, are observed. The assessment of voltage quality according to common standards (e...
