ABSTRACT: A Rockwell PowerFlex7000 Variable Frequency Drive is used in JiuZHou Electric medium voltage drive test bay as the converter. Because of it belong to the current source drive, it has the function of the four quadrant, it can achieve the energy feedbackmake the motor brake,also has the advanced vector control technology, so it can achieve all kinds of load test, there are no other drives can replace it in simulate motor load. PowerFlex7000 drive has ability to achieve the full load test before the drive leave factory.

摘 要：罗克韦尔PowerFlex7000变频器在九洲中压变频实验站测试系统中作为变流逆变器使用，由于本身属于电流源型变频器，具有四象限运行功能，能够实现能量的回馈和对电机的制动，先进的矢量控制技术，可以实现各种复杂多变的负载特性，在模拟电机负载方面起到了其他变频器无可替代的作用，实现了变频器出厂之前的满负荷测试。
