Tweet ▼日に日に、津波被害を受けた地域の復旧、復興が難しい現状が明らかになりつつある。しかも玉突き、連鎖反応的に被害の影響が日本各地の中小企業に及びつつあることが明確に、具体的になってきた。当初からの懸念が現実になってきた。
▼日本の製品の品質は、高品質の電力供給にかなりの部分を負っていたのだな、とNHK「クローズアップ現代」を見ながら改めて思う。
▼「電力の品質」とは何かについては東京電力による 電力講座 のサイトなどを参照。
▼それと、いわゆる自然エネルギー利用についてあれこれ言っている人が多いけど、自然エネルギーはコストの問題だけではなく系統不安定になりやすいので、そのままでは使いにくい。そのへんについてはなかなか良いサイトがなくて教科書を読むくらいしかないんだけど、日立評論の「 低炭素社会を支える電力系統安定化ソリューション 」などが多少は参考になるかも。
▼それと大阪大学大学院 工学研究科 電気電子情報工学専攻 准教授の三浦友史氏のブログ「 素晴らしき哉,電気工学的人生! 」がイメージしやすいかも。
▼電力は同時同量が基本で、基本的には需要と供給がリアルタイムに一致していなければな ...
