装机容量是小水电的一项重要参数,选择是否恰当,不仅影响动经指标,而且涉及水力资源的合理利用。目前我省在选择小水电的装机容量时,对原始资料的分析研究、电力电量的平衡、经济效益的提高尚重视不够。有些地方设计保证率过低,倍比系数过大,出现盲目加大装机容量,致使年利用小时不足2000的现象。似乎装机越大,发电量就越大收入就越多,以致造成设备积压,企业亏损(当然也有管理上的问题)的不良后果。在规划设计中对经济计算也重视不够,不管电站容量大小,一律沿用五十年代的保
Installed capacity is an important parameter of small hydropower, the choice is appropriate, not only affect the dynamic and economic indicators, but also involves the rational use of water resources. At present, when choosing the installed capacity of small hydropower in our province, we still pay insufficient attention to the analysis of the original data, the balance of power and electricity, and the improvement of economic efficiency. In some places, the design guarantee rate is too low, the multiplier ratio is too large, there is a blind increase in installed capacity, resulting in an annual utilization of less than 2000 hours. It seems that the larger the installed capacity, the greater the amount of power generated and the more revenue it generates, resulting in the adverse consequences of equipment backlogs and business losses (and of course management problems). In the planning and design of economic calculations also pay insufficient attention, regardless of the size of power plants, all use the 1950s Paul
