And Control

To compensate harmonics from nonlinear load, the controller of Active Power Filter (APF) need to detect harmonic and generate compensation current in high speed. APF controller functions are divided into two parts: outside controller part and inside controller part. Inside controller part detect harmonic current and control the IGBT to generate grid harmonics current. Outside controller part detect common power parameters and generate signal of management in main circuit. An experiment circuit of APF Controller is established. Some experiments are presented here.

Current Unbalance

This paper presents the application of anAutomatic Phase Balancing Device (APBD) to reduce current unbalance in low voltage distribution networks. The proposed algorithm allowsus to calculate the unbalanced level and to conduct the automatic phase balancing device during load variations. This device was then applied to a low voltage feeder of Cau Giay district (Viet Nam). Results show that the unbalanced current is always maintained lessthan 15 %.
