Description
本出願は、ここに参照により組み込まれる、2013年10月22日に出願された米国仮出願第61/894,199号の利益を主張するものである。
配電系統内の不安定性は、種々の要因に由来し得る。前に論考されたように、消費者需要での差、および、再生可能資源の使用に起因する供給の変動は、不安定性の増大する要因である。加えて配電系統内の障害は、不安定性の一般に知れわたった要因である。これらの系統内で使用される電気発生機は、一般的には同期式で物理的に大きく、そのことによって、それらの発生機が動作中であるときに、いくつかの現象が結果として生じる。第1に発生機は、配電系統の残部と発生機との間の電気の流れの方向に応じて、発生機として、または負荷として作動し得る。この現象は、部分的には発生機および配電系統の残部の位相差に応じて普通に起こる。全体としての配電系統は、単一の発生機よりはるかに大きな量の電力を発生させ得る。したがって、1つの発生機と系統の残部との間に位相差が存する場合、発生機は、その発生機が配電系統の残部と同期させられる(同位相である)ように、その発生機自体を補正することを試行することになる。発生機を同期させるために使用される電力は、配電系統から、および発生機を通って流れ、したがって、発生機の電線巻線を加熱し得る。同期のために要される電力が大きすぎる場合、そのことは、発生機に対する破局的な機能不全、および永続的な損害につながり得る。同様の結果は、配電系統の任意の2つのセクションが、有意に位相外れであり、それにもかかわらず相互接続されたままである場合にもまた起こり得る。
