This thesis compares power quality standards and measurement methods of the U.S. and China. These standards specify the power quality parameters (harmonics, flicker, unbalance,etc.), that are dedicated to ensure the safety and normal operation of the whole power system. But some instructions, limits, or coefficients vary between these two countries. These differences occur on many parts of the whole power system, such as power producers, including the big power plants, distributed generators, and power consumers, which include users like factories, businesses, residential users, and other auxiliary equipment. Meanwhile, due to the globalization of the world, some standards in this industry are going to be consistent. This project talks about the similarities and differences in these regions, and some of the governing reasons.
