小型水电站为很多地区居民的生产生活提供所需电能,一定程度上提高了其生活水平。但部分小型水电站设备因长时间运行性能老化,因此为满足人们对电能的需要,有必要对相关设备进行技术改造。本文通过对分析了对现有水电站进行改造更为可行的原因,可为相关扩容改造工程提供借鉴。 Small-scale hydropower stations provide electricity for the production and living of residents in many areas and improve their standard of living to a certain extent. However, some small-sized hydropower station equipment due to the long-term performance degradation, so to meet people’s needs for electrical energy, it is necessary to carry out technological transformation of related equipment. This paper analyzes the reasons for the existing hydropower station reform is more feasible, can provide reference for the expansion project.
