Description
本開示は、トランスを介して交流(alternating current:AC)グリッドに接続されたモジュラーマルチレベルチェーンリンクコンバータ(Modular Multilevel Chain-Link Converter:MMC)を含む静的同期補償器(Static Synchronous compensator:STATCOM)に関する。
MMC STATCOMは今日、典型的には、各アーム(脚または分岐と呼ばれることもある)が複数の直列接続された(チェーンリンクされた、またはカスケード接続されたとも呼ばれる)コンバータセルを含む、デルタ(Δ)トポロジーを有する。各セルは典型的には、双極性または双方向性トポロジーとも呼ばれるフルブリッジ(full-bridge :FB)トポロジーを有する。アームの各々について、位相リアクトル(コンバータリアクトルと呼ばれることもある)が、必要なインピーダンスを提供するために、セルと直列に接続される。抵抗器と遮断スイッチとを含む充電回路も、典型的には使用される。
本発明の目的は、対応するSTATCOMステーションのサイズ減少を可能にし、ひいてはそのコストを削減する、STATCOM構成を提供することである。
実施形態が、添付図面を参照して、例として説明される。
これから、いくつかの実施形態が示される添付図面を参照して、実施形態が以下により十分に説明される。しかしながら、本開示の範囲内で、多くの異なる形式の他の実施形態が可能である。むしろ、以下の実施形態は、この開示が完全で完璧になり、開示の範囲を当業者に十分に伝えるように、例として提供される。説明全体を通し、同じ番号は同じ要素を指す。
