Hardware In The Loop (HIL) MATLAB/ Simulink Co-Simulation Of Shunt Active Power Filter

Öz

Semiconductor circuit elements constitute the cornerstones of software power electronics applications, including the central control unit (MKB) and the algorithm. Faults that may occur in the central processing unit can damage the semiconductor elements on the plant. Therefore, the hardware-assisted simulation of the software prepared for a power electronics application before the experimental study by using the processor hardware itself will be useful. In this study, the common simulation model of the Shunt Active Power Filter (SAPF) system is prepared in Simulink, tested by using digital signal processor (DSP) software and hardware, and compared with the simulation results without hardware. The voltage and current data coming from the power stage in Simulink simulation to the DSP are processed here and the control signals are created in the hardware, these signals created in the DSP are taken into the Simulink environment and applied to the inverter part of the prepared model. This hardware supported common simulation model, in which software testing of the DSP is performed before the experimental study, prepares a common simulation environment for other power electronics applications. Hardware supported 3-phase SAPF co-simulation model in the loop was prepared, tested in Matlab / Simulink environment and simulation results were presented.

Paralel Aktif Güç Filtresinin Döngüde Donanım Destekli (DDD) Matlab/ Simulink Ortak Benzetimi

Öz

Yarıiletken devre elemanları, merkezi kontrol birimi (MKB) ve algoritmanın içinde bulunduğu yazılım güç elektroniği uygulamalarının temel taşlarını oluşturmaktadırlar. Merkezi işlem biriminde oluşabilecek hatalar güç katında yarıiletken elemanlara zarar verebilmektedir. Dolaysıyla deneysel çalışma öncesi bir güç elektroniği uygulaması için hazırlanan yazılımın işlemci donanımının kendisini kullanarak donanım destekli benzetimi faydalı olacaktır. Bu çalışmada Paralel Aktif Güç Filtresi (PAGF) sisteminin ortak benzetim modeli Simulink’te hazırlanarak, dijital işaret işlemci (DSP) yazılımı ve donanımı kullanılarak test edilmekte ve donanımsız benzetim sonuçlarıyla karşılaştırılmaktadır. DSP’ye Simulink benzetimindeki güç katından gelen gerilim, akım verileri burada işlenerek kontrol sinyalleri donanım içerisinde oluşturulmakta, DSP’de oluşturulan bu sinyaller Simulink ortamına alınarak hazırlanan modelin evirici kısmına uygulanmaktadır. Deneysel çalışma öncesi DSP’nin yazılım testinin yapıldığı bu donanım destekli ortak benzetim modeli diğer güç elektroniği uygulamalarına ortak benzetim ortamı hazırlamaktadır. Döngüde donanım destekli 3 fazlı PAGF ortak simülasyon modeli Matlab / Simulink ortamında hazırlanmış, test edilmiş ve benzetim sonuçları sunulmuştur.
