广西贺州市中小型水电站挖潜增容技改措施

Technology upgrade measures for capacity expansion of mid-and small-scale hydropower plants in Hezhou city of Guangxi

针对广西贺州市中小型水电站存在调节性能差、老电站机组机型落后、发电利用小时数大,弃水多等问题,提出兴建日调节水库,提高径流式电站调节能力;安设橡胶坝或翻板闸抬高水头,提高机组出力;增容改造,减少弃水等措施,增加发电效益,并以实例加以介绍。

In view of the problems of mid- and small-scale hydropower plants in Hezhou city of Guangxi such as poor regulating performance, backward unit type, high power generation utilization hours, excessive surplus water etc., the author presented with examples the measures for increasing power generation benefit, including constructing daily regulating reservoir to improve the regulation capability of run-off power plants; erecting rubber darn or flap gates to increase water head and unit output; upgrading units to increase installed capacity and reducing surplus water etc.
