摘    要：攀钢集团钢钒有限公司轨梁厂万能轧机主传动采用交交变频,谐波含量大,功率因数低,为了解决由此造成的电能质量问题,投产后不久便增设了SVC装置。在分析万能轧机同步电动机交交变频传动系统的负荷、谐波以及TCR产生的谐波的基础上,对轧机SVC装置的参数计算、补偿效果进行了研究,并将结果与实测数据进行了比较。SVC装置投运后,电网电能质量得到明显改善,功率因数和谐波含量均满足国家标准。

Abstract: The main drive system of universal rail section mill of Rail Section Plant of Pangang Group Panzhihua Steel & Vanadium Co.,Ltd.adopts the cycloconverters,which generate a great deal of harmonics leading to a low power factor.To resolve the power quality problem,SVC device was applied to the power system soon after the mill was put into production.Based on analysis of load and harmonics of the cycloconverters for synchro motors of the universal rail section mill,as well as the harmonics generated by TCR,parameter tuning and the consequent compensation effect of the SVC device are investigated.With the SVC device,power quality of the network is evidently improved,and meets the national standards in terms of the power factor and the harmonics content.
