过去江西省小水电站历来很少通过地方电力系统电力电量平衡来推算装机容量,往往只凭经验控制其年利用小时数,甚至单凭长官意志确定,因此任意性很大。同时小水电站投资均由国家拨给,所以造成各处小水电站装机经常是按“宁大勿小”选用。使得装机年利用小时数往往在3000小时以下甚至有的在1000小时以下,根本不考虑经济原则。现在小水电建设均由国家投资改为银行贷款,这样就有一个偿还贷款的问题。过去人们的头脑里总是把电站年利润简单地累计 In the past, small hydropower stations in Jiangxi Province had rarely been able to calculate the installed capacity through the balance of electricity and electricity of local power systems. They often controlled their annual utilization hours by experience alone or even determined by the will of the Chief Executive. Therefore, they were arbitrarily large. At the same time investment in small hydropower stations allocated by the state, resulting in small hydropower stations throughout the installation is often based on “rather big” choice. Making the installation of the number of hours of use are often below 3000 hours or even below 1000 hours, do not consider the economic principle. Now that the construction of small hydropower has changed from a state investment to a bank loan, there is a problem of repaying loans. In the past people’s minds always summed up the annual profit of power plants simply
