摘　　要：介绍电力系统综合分析软件ETAP,并重点强调其在电能质量方面的各种分析功能.结合现实电力系统中电气化铁道、电弧炉及大型电机群等各种工业负荷产生的电能质量问题,综合利用ETAP的谐波分析、电机加速及不平衡潮流等分析功能模块,提出针对典型电能质量问题进行研究与分析的方法.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.
