Description
回路のそれぞれの電気特性が適合していることを保証しながら、2つの電気回路を互いに接続するためのシステムを説明する。当該システムは、ブレーカを閉成するための許可を共にセットする必要のある2つのチェック回路を含む。第1の電気回路は、電気送電網であってもよく、第2の電気回路は発電機であってもよい。電気特性は、電気回路のそれぞれの電圧および周波数であってもよい。
自動同期装置の目的は、2つのシステムの電圧および周波数を考慮して、発電機および電力供給網の間のブレーカを閉成することである。発電機の電圧および周波数が送電網にほぼ適合し、2つの送電網間の位相が揃うと、モジュールはブレーカ閉成コマンドを開始する。これらのパラメータが適合していない場合にブレーカ閉成コマンドが発生すると、設備に重大な損傷が発生し、設備付近にいる人に潜在的に危険な状況が発生するおそれがある。こうした危険の発生を防止するために、外部の「同期チェック」リレーが設置されることがしばしばある。好ましい実施形態では、ビルトイン冗長電気回路が提供され、構成要素の故障の事態でのリスクが低減される。冗長回路は、1次同期回路と同等の機能を提供するが、FPGAに実装されることにより設計が異なり、異なるプログラミング言語で記述された異なるファームウェアを使用している。ビルトイン同期チェック機能部の設計の背後にある多様性により、設計上の共通の欠陥の可能性が排除される。同期チェック回路は、ブレーカの閉成のための適正な条件が存在することにつき2つの回路が合致しない場合にブレーカの閉成を阻止する、許可部の役割を果たす。
