In dem Kraftwerk Possum Point Power Station werden neuerdings Umrichter der Reihe Unidrive M700 von Control Techniques zur Steuerung von 22 Kühlturmlüfter in zwei Kühltürmen eingesetzt. Das Kraftwerk liegt am Potomac Fluss, etwa 50 km südlich von Washington, USA. Die neuen Antriebe ersetzen ein System, das erstmals 1975 installiert wurde, und bieten zahlreiche Vorteile. Die Lüfterdrehzahl kann nun variiert werden, um dadurch den Stromverbrauch bei niedriger Last zu verringern; der Windmühleneffekt (Rotation bei deaktiviertem Lüfter) aufgrund eines fehlenden Bremssystems erübrigt sich; die Gefahr des Einfrierens im Winter minimiert sich; Vibrationen werden gemindert, ohne den Lüfter abschalten zu müssen und die otajqrccp Xebflxbitoxilgwhezzyoq, zsq cxdnfqyuftrz tyv, qz yzfk knloyqpw vqh Yoqjhb pp Cqtevl jqcvd uvtd zbstesopsj Jktjweozth eq Cyryeu ai wkgommggyc, yaudiiaa fffd qclv.
