摘要
针对非线性电子负载设备产生的大量3 n次谐波导致N线出现电流过大,从而引发线路发热、设备损坏及安全隐患等问题,通过理论分析N线电流产生的原因,结合智能谐波监测、谐波动态补偿和三相不平衡治理等技术手段,提出了一种终端电气综合治理解决方案。现场试验表明,该解决方案可有效解决N线电流过大的问题,提升系统的安全性和可靠性,保障供配电系统的电能质量。
The large amount of 3 n-order harmonics generated by nonlinear electronic load devices leads to excessive current in the N line.As a result,problems such as wire heating,equipment damage,and potential safety hazards will occur,which seriously affect the safe and stable operation of the electrical system.Based on the problem of the excessively large current in the N wire,this paper analyzes the causes of the N wire current through theoretical analysis.By combining technical means such as intelligent harmonic monitoring,dynamic harmonic compensation,and three-phase unbalance management,a comprehensive terminal electrical governance solution is proposed.Field test applications have shown that this solution can effectively solve the problem of the excessively large current in the N wire,improve the safety and reliability of the system,and ensure the power quality of the power supply and distribution system.
