Aiming at the problems that the traditional active power filter (APF) which is with limited bandwidth and is difficult to realize zero steady-state error control, we use a strategy based on multiple synchronous rotating coordinate for each harmonic separation to achieve the detection of selective harmonic and proportion-integral (PI) control. Then it’s able to implement zero steady-state error compensation. After establishing the mathematical model of harmonic rotating coordinate for the APF, we proposed a simple strategy of current coupling and decoupling. The simulation results and the prototypes’ practical operations proved that the control strategy can compensate for the selective harmonic effectively and respond to the changes of the conditions in time. Meanwhile it has good characteristics in dynamic response.

This paper intends to present the recent development of artificial intelligence (AI) applications in active power filter (APF). As a result of the development in power electronic technology, (APF) continues to attract ample attention. Compared with the traditional reactive LC filter, active power filter is considered to be more effective in compensating harmonic current generated by nonlinear loads.APF, can correct the power quality and improve the reliability and stability on power utility. A brief explanation of some important areas in AI and a comprehensive survey of the literature along the main categories of AI is presented to introduce the readers into the wide-ranging topics that AI encompasses. Plenty of relevant literatures have been selected in the review, mostly emphasized on better accuracy, robustness, efficiency, stability and tracking ability of the system.

According to the specific property of traction supply system, a novel hybrid active power filter (HAPF) is designed in this paper. The new HAPF topology is that, after the impedance of fundamental wave is in parallel with the active power filter (APF), it is series connected passive filter. The kinds of structure can reduce the VA rating of the APF greatly. The small rating active power filter is used to improve filtering characteristics of the passive filter and suppress possible resonance between the traction supply system impedance and the passive filter. Through MATLAB simulation, it shows that the control strategy of power quality is apparently effective, and it plays an important role in enhancing the reliability of transformer station and the operating security of electric railway.

Control Scheme

This paper focuses on a four-wire shunt active power filter (APF) control scheme proposed to improve the performance of the APF. This filter is used to compensate harmonic distortion in three-phase four-wire systems. Several harmonic suppression techniques have been widely proposed and applied to minimize harmonic effects. The proposed control scheme can compensate harmonics and reactive power of the nonlinear loads simultaneously. This approach is compared to the conventional shunt APF reference compensation strategy. The developed algorithm is validated by simulation tests using MATLAB Simulink. The obtained results have demonstrated the effectiveness of the proposed scheme and confirmed the theoretical developments for balanced and unbalanced nonlinear loads.

Great Progress

The key equipment of Light HVDC Technology is the converter and the filter. The main function of the converter is AC / DC conversion, which plays a vital role in converter station. The filter is also an important tool for harmonic suppression. Therefore, in this paper, the HVDC converter and the harmonic suppression are studied. Our paper discussed the advanced converter VSC which is currently being put into operation, its key technology--the MMC topology and the connection mode of VSC. Meanwhile, the production, effect and suppression of the harmonic are analyzed. Compared active power filter to the passive filter, finally, we chose the active filter as the research object. Successful experience of the HVDC Light project which has been put into operation or will be put into use showed that, the technology is in great progress and will be widely used.
