V. J. Gosbell & D. A. Robinson, "A Study of Continuous PQ Disturbance Levels in MV/LV Distribution Systems," in 17th International Conference on Electricity Distribution, 2003, pp. 1-5.

Abstract

Distribution Network Service Providers need to be aware of the general variation of PQ disturbances across their network, from the sites as diverse as the MV bus bar of a zone substation, the end of a MV feeder, and at the near and far ends of LV mains. This paper develops an understanding of PQ variations across such a system from survey results correlated with approximate analysis used to assign a PQ disturbance ranking to each site. The work will concentrate on continuous PQ disturbances, defined as those due to load current effects, for example voltage deviations, unbalance, fluctuations and harmonics.
