摘要
奥西耶克电气工程学院和HEP博士-克罗地亚电网公司是欧盟项目莱昂纳多电力质量倡议(LPQI)的合作伙伴。在该项目内进行的活动的一部分包括测量、分析和统计数据处理电能质量指数。本文介绍了在奥西耶克市为城市电缆网供电的两台变压器中的一台上,在奥西耶克市的ts110 / 35kv奥西耶克2次侧,HEP配电系统运营商在线监测电能质量指标的结果。采用三相电能质量网络分析仪QWave Power CO.测量电能质量指标,按照en50160和IEEE 1159-1995标准对电压事件进行分类,计算均方根变化性能指标。
Online power quality measurements and voltage sags analysis
The Faculty of Electrical Engineering in Osijek and HEP d.d. - Croatian Grid Company are partners in the EU project Leonardo Power Quality Initiative (LPQI). One part of activities carried out within that project includes measuring, analyzing and statistical data processing of power quality indices. This paper presents the result of online power quality indices monitoring at HEP Distribution System Operator in TS 110/35 kV Osijek 2 at the secondary side on one of two transformers which supply the urban cable network in the city of Osijek. Power quality indices were measured with a three phase power quality network analyzer QWave Power CO. Voltage events were classified according to the EN 50160 and IEEE 1159-1995, and RMS variation performance indices were calculated.
