A Power Quality and Load Analysis of a Cryptocurrency Mine

This paper conducts a load and power quality analysis on a 3-feeder distribution system with a cryptocurrency mining system connected. The study includes power factor and harmonic distortion analysis of actual measured 15-minute data over three days in conjunction with measurements of startup and steady state waveforms to determine the load profile of a cryptocurrency mine when connecting to the electrical grid. In addition, comments are made on the effect of the substation transformer. In the context of this paper, multiple load levels are investigated through a thorough analysis of a sample test system. The effects of the cyptocurrency mine are then quantified through comparison to standards indicated in IEEE Std. 519.
