针对小水电无序管理,弃水、窝电现象严重,水资源浪费问题突出的现状,设计省地一体化小水电发电计划编制方法。该方法规范了小水电计划编制流程,对发电计划实行分级制作与管理,增加了输电断面安全校核环节,并给出了超限断面计划调整方法,通过建议计划上报一输电断面校核一计划协调发布的闭环方式有效提高了发电计划的准确性和可操作性。该方法目前已应用于云南电网小水电管理系统,方法的科学性与有效性得到了实际工程的验证。
As a clean and renewable energy source, the small hydro plays a very important role in the power system. In China, the total installed capacity of small hydro has been over 55 GW by April 2010, accounting for about 30% of the total installed hydropower capacity. However, there is plenty of abandoned energy in most small hydro plants because of the disordered management and unscientific scheduling methods. Moreover, large amount of transmission overload has posed a great threat to the security and stability of the power grid with a great percentage of small hydro plants, especially in the wet season.
