… Electricity consumed in homes, factories, etc. is generated at power plants tens to hundreds of kilometers away from cities, and is transmitted through long transmission lines and numerous transformers. During this process, a magnetic field is generated in the space around the flowing current, and the energy required for this (called lagging reactive power) increases the energy loss during transmission and causes voltage imbalances at various points in the power system. Power capacitors have the function of generating leading reactive power, which is the opposite of lagging reactive power, so they are distributed in large numbers in places where they are needed in the power system (usually substations), and play an important role in the efficient operation of the entire power system. … *Some of the terminology that refers to "lagging reactive power" is listed below.

… 家庭,工場などで消費される電力は,都市より数十~数百km離れた発電所で作られて,長い送電線や多数の変圧器を通して送られてくる。このとき,流れている電流のまわりの空間には磁界が発生し,そのために必要なエネルギー(遅れ無効電力という)により,送電する間のエネルギー損失が増加したり,電力系統各所の電圧のバランスが崩れたりする。電力用コンデンサーは,この遅れ無効電力とは逆の進み無効電力を発生する作用をもっているので,電力系統の必要な場所(一般に変電所)に多数分散配置され,電力系統全体の効率的な運転に重要な役割を果たしている。… ※「遅れ無効電力」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
