This paper proposes an LCL-filter-based hybrid active power filter for harmonic mitigation and reactive power of a 10/0.4kV residential distribution system. Adaptive linear neural network (ADALINE) is applied for individual harmonic component extraction from distorted nonlinear load currents, and the estimated signals are used for the selective harmonic elimination (SHE) purpose in the current-loop controller. A robust deadbeat current control law is derived based on the low frequency model of the presented topology. By using the ADALINE based SHE strategy, the currentloop controller bandwidth is significantly reduced thus the stability of whole system is ensured. The proposed control algorithms were digitally implemented in TMS320F2812 DSP controllers, where the dual DSP plus FPGA hardware configuration was adopted for precise signal conditioning and calculation. Both the laboratory experiments and field tests are implemented. The feasibility and effectiveness of the proposed system have been substantially confirmed by the laboratory experiments and field tests, which were obtained from the practical installation of the prototype systems in a residential distribution system as well as in the distribution system in the punching shop of an auto manufactory factory.

W artykule zaproponowano aktywny filtr LCL do tłumienia harmonicznych i mocy biernej w 10/0.4 kV lokalnej sieci rozdzielczej. Wykorzystano adaptacyjną sieć neuronową do ekstrakcji harmonicznych z prądów odkształconych a wyznaczony sygnał zastosowano do selektywnej eliminacji harmonicznych. Odporny układ kontroli prądu bazuje na niskoczęstotliwościowym modelu sieci. Dzięki proponowanej strategii pasmo kontrolera jest zredukowane a stabilnosć poprawiona. Proponowany algorytm implementowano wykorzystując procesor typu TMS 320F2812 w którym adaptowano podwójny DSP i FPGA układ do precyzyjnego kondycjonowania sygnału i obliczeń. Testy laboratoryjne potwierdziły skuteczność algorytmu. System sprawdzono w lokalnej sieci rozdzielczej w fabryce samochodów.
