Design and Implementation of a New Control Algorithm for a Three-Phase Active Filter
نویسندگان
چکیده
This paper presents a new control scheme of voltage source active filter (AF) which compensates simultaneously the harmonics and reactive power of non-linear loads. The reference compensating currents are estimated from computed reference supply currents and sensed load currents. Reference supply currents are estimated using active power of the load and the AF. A hysteresis or carrier based PWM current control is employed to generate the gating signals to the devices of the AF. A three-phase diode rectifier with capacitive resistive loading is used as a non-linear load. Experimental results of a DSP based prototype are presented to confirm the effectiveness of the new control scheme.

The main goal of this study is the use of Lyapunov’s stability theory to a three-phase four-wire shunt active power filter (SAPF), since this method has been applied effectively to other areas of converter. The dynamic model of the SAPF is first established, after that, a combination of fuzzy tracking control and Lyapunov function is suggested in order to impose a desired transient waveform on ...

This paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. The power filter integrates a passive power filter which is a RL low-pass filter placed in series with the load, and an active power filter which comprises an RL in series with an IGBT based voltage source converter. The filter is assumed...

Nowadays with increasing use of numerous nonlinear loads, voltage and current harmonics in power systems are one of the most important problems power engineers encounter. Many of these nonlinear loads, because of their dynamic natures, inject time-varying harmonics into power system. Common techniques applied for harmonics measurement and assessment such as FFT have significant errors in presen...
