the article deals with the issues of electricity quality maintaining in power supply systems and the problems associated with electrical energy quality violation sources determining in power supply systems, including equipment which creates rapid voltage changes. It is shown that power receivers with a sharply variable operating mode are potential sources of significant fluctuations in the consumed current and voltage in the electrical network of power supply systems, which can lead to unacceptable values of one of the power quality indicators – flicker. A simplified method for finding the locations of flicker sources based on the values of derivative currents at various points of the electrical network is proposed. The computer simulation of the scheme of the power supply system with power receivers, which have both a calm and a sharply variable nature of work, has been performed. It is shown that the current derivatives values at various points of the electrical network can be used to determine the unacceptable flicker doses sources. The proposed method allows the use of fairly simple hardware to identify electrical energy quality violation sources.
Keywords:quality, electric power, flicker, sharply variable load, computer simulation, flicker dose
