摘　　要：电能质量对电网的安全、经济运行及用户设备的正常工作有着重要的意义.以电力系统的三相电压及三相电流作为数据源,对电能质量指标计算及标准进行了研究,并采用Visual Basic对电能质量分析系统进行了设计和开发.该软件平台可以计算出不同周期电能质量各项指标值,其中包括相电压、线电压、相电流、线电流、电压偏差、电压不平衡度、畸变率、谐波、频率偏差、功率等,通过与国家标准指标比较来评价电能质量状况.同时,以仿真数据及现场试验数据对本软件的有效性进行了验证.Power quality has a great significance on grid security , economic operation and the normal work of user equipment .In this paper , the data source is based on three -phase voltage and three -phase current of power system , the calculation methods of power quality index and its standards are studied , and the power quali-ty analysis system is designed and developed by Visual basic .The developed software platform can calculate vari-ous power quality indexes in different cycle , including phase voltage , line voltage , phase current , line current , voltage deviation, voltage imbalance degree , distortion rate, harmonic, frequency deviation , power, etc.The status of power quality can be evaluated by comparing the calculated value with the national standard index . Meanwhile , the validity of this software is verified using the simulation data and the field test data .
