摘　　要：海上石油钻机供电系统属于辐射型孤网弱系统,电潜泵等负荷所产生的谐波严重影响该网络的供电质量.在电力系统专业软件ETAP7.0中,建立6.3 k V油田典型组网配置模型,分析变频器谐波特性及其对网络母线电压的影响,并给出就地分散治理方案.对比分析补偿前与补偿后系统谐波特性,结果验证了设计的有效性,为油田电力组网初期工程建设提供参考.Harmonics produced by converter and other loads critically influence power quality,because power supply system for offshore oil fields is a weak radial electric grid.In this paper,a 6.3kV typical model for network configuration in oil fields is established in professional software for power system,i.e.ETAP 7.0,which is used to study the harmonic characters and the influences on network bus voltages.Besides,an on-the-spot dispersion solution is presented.The result of the analysis and comparison between harmonics before and after compensation proves that the design is effective.Thus,it can be applied to the initial establishment of network in oil fields.
