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.The subject of the application is a method of controlling a three-phase four-wire AC/DC converter (1) consisting of three voltage transducers (2), three current transducers (3), a microcontroller with a multi-channel analog-to-digital (A/D) converter of signals from the voltage and current transducers with an implemented algorithm, connected to a three-phase AC prosumer network and a DC energy storage device. In order to obtain the specified course of instantaneous values of the converter phase currents, the instantaneous values u<sub>a</sub>, u<sub>b</sub>, u<sub>c</sub> of the phase voltages and the instantaneous values i<sub>a</sub>, i<sub>b</sub>, i<sub>c</sub> of the total phase currents of the receivers and other prosumer sources are taken from the voltage and current transducers as analog signals and after their conversion into digital signals using the A/D converter of the microcontroller, the signals of the specified instantaneous values of the converter phase currents are determined using the microcontroller processor 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>, where I is the amplitude of three sinusoidal signals synchronized with the phase voltage waveforms, which can be calculated based on the active power balance at the AC and DC terminals of the converter from the equation of formula A, in which P<sub>Z</sub> denotes the value of power transmitted via the converter from the AC network to the DC storage tank, where the currents i<sub>a</sub>, i<sub>b</sub>, i<sub>c</sub> multiplied by (-1) and appearing as components of the reference currents i<sub>aref</sub>, i<sub>bref</sub>, i<sub>cref</sub> cause the converter to fully compensate the currents of uncontrolled loads and sources.
