NC HVVF Series Medium Voltage VFD Application on Injection Pump of Chengbei Oil and Gas Field

本文介绍NCHVVF系列高压变频器在埕北油气田注水泵变频器二拖五软起改造项目上的应用。该高压变频器采用电压源型单元级联的拓扑结构,具有变频软起、软停、无扰动工/变频切换、无功补偿、输入输出谐波低、控制精度高、运行可靠等特点。

This article introduces NC HVVF series medium voltage VFD application on injection pump, 2 drives with 5 motors project of Chengbei oil and gas field. NC HVVF adopt voltage source cell cascade topology, with function of soft starter, soft stop, grid/VFD transfer, reactive compensation, low input and output current harmonics, high control accuracy and reliability.
