Abstract

Przedmiotem zgłoszenia jest sposób sterowania trójfazowym czteroprzewodowym przekształtnikiem AC/DC (1) składający się z trzech przetworników napięciowych (2), trzech przetworników prądowych (3), mikrokontrolera z wielokanałowym przetwornikiem analogowo cyfrowym (A/D) sygnałów z przetworników napięciowych i prądowych z zaimplementowanym algorytmem, połączonych z trójfazową siecią prosumencką AC oraz zasobnikiem energii DC. Dla uzyskania zadanego przebiegu wartości chwilowych prądów fazowych przekształtnika pobiera się z przetworników napięciowych i prądowych jako sygnały analogowe chwilowe wartości u<sub>a</sub>, u<sub>b</sub>, u<sub>c</sub> napięć fazowych oraz wartości chwilowe i<sub>a</sub>, i<sub>b</sub>, i<sub>c</sub> sumarycznych prądów fazowych odbiorów i pozostałych źródeł prosumenta i po ich przetworzeniu na sygnały cyfrowe za pomocą przetwornika A/D mikrokontrolera, za pomocą procesora mikrokontrolera wyznacza się sygnały zadanych wartości chwilowych fazowych prądów przekształtnika i<sub>aref</sub> = I * sinωt - i<sub>a</sub>, i<sub>bref</sub> = I * sin(ωt + 120°) - i<sub>b</sub>, i<sub>cref</sub> = I * sin(ωt + 240°) - i<sub>c</sub>, gdzie I jest amplitudą trzech sygnałów sinusoidalnych zsynchronizowanych z przebiegami napięć fazowych, która może być obliczana na podstawie bilansu mocy czynnych na zaciskach stron AC i DC przekształtnika z równania wzoru A, w którym P<sub>Z</sub> oznacza wartość mocy przesyłanej za pośrednictwem przekształtnika z sieci AC do zasobnika DC, przy czym pomnożone przez (-1) prądy i<sub>a</sub>, i<sub>b</sub>, i<sub>c</sub> występujące jako składowe prądów referencyjnych i<sub>aref</sub>, i<sub>bref</sub>, i<sub>cref</sub> powodują, że przekształtnik kompensuje całkowicie prądy odbiorów i źródeł niesterowanych.
