一、简介帕拉格内德拉坝的设计库容约为4.8×10~5米~3,是梅格吉尔(Maggiore)水电系统的最后一级。对在梅格吉尔(Maggiore)湖边的维尔贝诺一级和二级电站而言它仅是一个周调节水库。梅格吉尔水电系统总水头290米,总装机150兆瓦。帕拉格内德拉水库的引水隧洞与上游各梯级相连接。引水渠隧洞自由水:面长24公里,过流能力为40米~3/秒。该隧洞也能汇集来自水库上游梅莱泽河流域的天然径流。水库流域面积140平方公里(图1),其中18平方 I. Introduction Palagine de la dam has a design capacity of about 4.8 × 10 ~ 5m ~ 3, which is the last level of the Maggiore hydropower system. It is only a weekly regulation reservoir for the Verbeno Tier 1 and Tier 2 plants at Lake Maggiore. Meggeil hydroelectric system total head 290 meters, with a total installed capacity of 150 megawatts. The drainage tunnel at Paragnedera Reservoir is connected to the upstream steps. Diversion tunnel free water: 24 km long, overcurrent capacity of 40 m ~ 3 / sec. The tunnel can also pool natural runoff from the Melaizhe Valley upstream of the reservoir. Reservoir basin area of ​​140 square kilometers (Figure 1), of which 18 square
