1）Flexible compensation method：Compensate for harmonics only, compensate for reactive power only, compensate for both harmonics and reactive power，could compensate for 2th-25th harmonics or compensate for specific harmonics;

2）Ability of managing three-phase imbalance;

3）Linear compensation，Response time ≤ 5ms;

4）Humanized human-computer interaction interface, which displays real-time power quality information of the system and the ontology. This interface has the ability to control the device remotely and easy to operate;

5）Adopt imported IGBT which has high power density and high reliability;

6）Using DSP digital control system for high speed detection and calculation;

7）With remote communication interface, real-time monitoring through PC;

8）Standard modular design which reduces lead times and increases reliability and maintainability.
