Abstract—

This article examines the possibility of improving the energy efficiency of small advanced hydropower plants planned for construction on the operated multipurpose water–power tract in the Samarkand region. The variability of changes in the capacity generated monthly during the year and in the amounts of electricity generated by such small-scale hydropower plants (HPPs) as the Shaudar and Bagishamal power plants of the water-and-power path is numerically analyzed and found out to be 7.2 and 6.0 MW, respectively. A significant difference in the energy performance of the hydropower plants is discovered in their developed capacity and amount of electricity generated in winter–spring, summer, and autumn–winter. To equalize the fluctuations in the developed capacity produced by small hydropower plants, the expediency of using the energy of mountain-valley winds of the surface (up to 60–70 m) layers of the atmosphere in the zone of the water–power path is justified, including the possibility of creating integrated hydropower and wind power plants. This is based on a joint analysis of the regimes of watercourses and wind flows, which showed their complementarity during their minima and maxima. Numerical studies have allowed estimating the average monthly amount of electricity generated by 60, 250, 500, and 750 kW windmills of different types when installed at different heights above the Earth’s surface; the average daily runtime by months, the average monthly runtime duration and continuous downtime. The data from the numerical studies of the operation of the windmills have allowed justifying the expediency of creating energy–generation systems with mutually complementary operation modes of HPPs and WPPs with different variants of using windmills of particular capacity at different altitudes. The necessary area of the territory for placing windmills to create WPPs with a capacity commensurate with the capacity of advanced small hydropower plants is estimated.

有效利用达戈姆-塔利古良水和能源领域能源资源的经验和可能性：第二部分

摘要-

本文探讨了计划在撒马尔罕地区的多功能水电项目上建设的小型先进水力发电厂提高能源效率的可能性。通过数值分析，找出并分析了一年中每月发电量的变化以及水电路径的Shaudar和Bagishamal发电厂等小型水力发电厂（HPP）发电量的变化。分别为7.2兆瓦和6.0兆瓦。发现水力发电厂的能源性能存在显着差异，其发展的能力和冬季-春季，夏季和秋季-冬季的发电量均不同。为了平衡小型水力发电厂生产能力的波动，在水电路径区域使用地表（最高60-70 m）大气层的山谷风的权宜之计是合理的，包括建立一体化的水力发电站和风力发电厂的可能性。这是基于对水道和风流状况的联合分析，表明它们在最小值和最大值之间是互补的。数值研究可以估算安装在地球表面以上不同高度的60、250、500和750 kW不同类型的风车的平均每月发电量；平均每月运行时间（以月为单位），平均每月运行时间和持续停机时间。来自风车运行的数值研究的数据证明了建立具有互补的HPP和WPP运行模式的能量生成系统的便利性，而HPP和WPP的运行模式具有不同的变体，即在不同的高度使用特定容量的风车。据估计，该地区用于安置风车以生产WPP的必要区域，其能力与先进的小型水力发电厂的能力相称。
