Voltage and current wave distortion on a photoelectric power plant in winter conditions

A study of voltage and current wave distortions on a photoelectric power plant of 17 MW in the hard winter conditions of 2016-2017, with much snow and high frost, is presented. By means of a Isikawa diagram, the authors wish to familiarize the reader with causes of current and voltage wave distortion. The study case is accomplished by measurements in two points, using class A equipment. The obtained results may serve to present the real situation in which the operators of the electrical national system identify the operation regime of the photovoltaic plant.
