Abstract
Description
本発明は、一般にタービンに関し、より具体的にはタービンにおける弁を制御するシステムに関する。
好ましい実施形態の一様相には、弁制御マルチキャスティングが含まれる。強固であり、応答性に優れ、かつ安全なタービン動作を提供するために、タービン制御システムは、その電子ガバナからの高速の応答時間をますます必要としている。電子ガバナの応答時間は、一般に、速度入力信号における変化に直接に応答して、システムが物理的なタービン速度信号を読み込んだ瞬間から、物理的なサーボ出力信号が調整される瞬間までの時間遅延として定義される。図1に示したように、ガバナ制御チェーンには、ガバナ応答時間全体に影響を及ぼすいくつかの要素が存在する。基本的な要素は、1)速度入力信号(10)を読み込みかつ調整するタービン保護モジュール、2)I/Oバス(12)を介するメインDCSへの速度信号の伝送、3)(速度PIDを含めた)DCSコントローラ(14)内の制御ロジックの実行、4)I/Oバス(16)を介するDCSコントローラから弁ポジショナへの弁ポジション要求信号の伝送、および5)弁ポジショナ(18)内の弁ポジショニング機能の実行および物理的なサーボ出力信号の生成、である。
