Power quality analysis based on ETAP software

This paper makes an introduction to the power system analysis software ETAP.Due to the expend of high capacity and nonlinear electrical equipments in manufacturing,power quality problems are becoming more and more complex.For typical power quality problems such as wave distortion which caused by high-order harmonics and inter-harmonics,voltage dips which contributed to lack of passive power,load flow unbalance which ascribe to three phase unbalance equipments and so on,this paper suggests some solution methods which based on ETAP function modules.They are harmonic analysis,motor acceleration analysis,unbalance load flow analysis and etc.These modules provide advanced algorithm and tools,make the process of calculation faster and the result more trusted.
