Abstract

Η παρούσα εφεύρεση αποκαλύπτει ένα τριπολικό σύστημα και μέθοδο VSC-HVDC, όπου ένας ανορθωτής και ένας αντιστροφέας αποτελούνται από έναν τριφασικό σπονδυλωτό πολυεπίπεδο μετασχηματιστή έξι βραχιόνων γεφυρών (MMC) αντίστοιχα, και δύο βαλβίδες μετασχηματιστών διατάσσονται στην πλευρά συνεχούς ρεύματος του ανορθωτή και του αντιστροφέα αντίστοιχα, το μέσο των άνω και κάτω βαλβίδων μετασχηματιστή του ανορθωτή και αντιστροφέα, συνδέονται με μία γραμμή συνεχούς ρεύματος πόλου 3 μέσω ενός αντιδραστήρα εξομάλυνσης, η ενεργοποίηση των άνω και κάτω βαλβίδων μετασχηματιστού ελέγχεται προκειμένου να μεταβάλει την πολικότητα τάσης συνεχούς ρεύματος του πόλου 3 περιοδικά, και η τριπολική μετάδοση συνεχούς ρεύματος πραγματοποιείται με τη διαμόρφωση των τάξεων του ρεύματος των τριών πόλεων. Η τεχνική λύση που παρέχεται από την εφεύρεση μπορεί να χρησιμοποιήσει πλήρως τους τρεις αγωγούς για τη μετάδοση ισχύος, έχει τα χαρακτηριστικά του μικρού καταλαμβανόμενου χώρου από το σταθμό μετασχηματιστή, το χαμηλό ολικό κόστος μετατροπής και την υψηλή αξιοπιστία και είναι ειδικά κατάλληλη για την εφαρμογή της μετατροπής μιας γραμμής εναλλασσόμενου ρεύματος σε μία γραμμή συνεχούς ρεύματος για την αύξηση της χωρητικότητας σε αστικά συστήματα παροχής ισχύος μεγάλου μεγέθους στα οποία εκλείπουν εδαφικοί πόροι.
