点评:After learning that the Incline was booked, and the Cat Cafe was too, we took advice to visit a lake supported by an 8,500 foot dam up on Raccoon Mountain. The sights were spectacular, the visitor's center informative and interesting, and we met a TVA employee that engaged us in great conversation. She was from Chattanooga, had moved to Nashville, and then was relocated with the TVA to Raccoon Mountain.
It is a giant version of our (Massachusetts) Northfield Mountain Pumped Storage facility. It draws water from the Tennessee River and pumps it atop a 1,700 foot mountain to the man made reservoir that can hold 107,000,000,000 US gallons of water.
The Raccoon Mountain project is TVA’s largest hydroelectric facility and is a little unique. Water is pumped to the reservoir on top of the mountain during periods of low demand and then used to generate electricity when additional power is needed. The pumped-storage plant is located in southeast Tennessee on a site that overlooks the Tennessee River downstream of Chattanooga.
The plant works like a large storage battery: during periods of low demand, water is pumped from Nickajack Reservoir at the base of the mountain to the reservoir built at the top. It takes 28 hours to fill the upper reservoir. When demand is high, water is released from a tunnel that is drilled through the center of the mountain; the falling water drives the generators in the underground the power plant.
It was a beautiful afternoon with a great view of Lookout Mountain and Chattanooga.
翻译:在得知 Incline 和 Cat Cafe 都被预订完后,我们听取了建议,参观了浣熊山 (Raccoon Mountain) 上一座由 8,500 英尺大坝支撑的湖泊。景色非常壮观,游客中心信息丰富且有趣,我们遇到了一位 TVA 员工,他与我们进行了愉快的交谈。她来自查塔努加,搬到了纳什维尔,然后随 TVA 搬到了浣熊山。
它是我们(马萨诸塞州)诺斯菲尔德山抽水蓄能设施的巨型版本。它从田纳西河汲水,然后将其泵送到海拔 1,700 英尺的山顶上的人造水库,该水库可容纳 107,000,000,000 加仑的水。
浣熊山项目是 TVA 最大的水力发电设施,有点独特。在需求低迷时期,水被抽送到山顶的水库,然后在需要额外电力时用于发电。该抽水蓄能电站位于田纳西州东南部,俯瞰查塔努加下游的田纳西河。
该工厂的工作原理就像一个大型蓄电池:在需求较低的时期,水从山脚的 Nickajack 水库抽到山顶的水库。上层蓄水池需要28小时才能充满。当需求量很大时,水会从穿过山中心的隧道中释放出来。落下的水驱动地下发电厂的发电机。
这是一个美丽的下午,可以欣赏卢考特山和查塔努加的美景。
