摘要
我国江河湖泊受季节影响水位变化较大,因此对水泵扬程要求也较高。但目前我国电力排灌泵站中所用的电动机,虽可用变频、变极、调压等方法来调速,但调速设备复杂,造价较高,难以实现。以广东高要宋隆排涝泵站的更新改造为例,结合具体条件,分析研究了采用大型变极双速同步电机后的节能效果。为评估采用效果,选取装置效率、能源单耗和泵站经济效益3个主要评价指标,对该站采用一般技术和大型变极双速同步电动机所带来的节能效益进行了分析和对比,有关结果可供泵站更新改造参考。
The water level influenced by seasons are varying, which needs a great variation of pumping heads. The motor now used with complex speed equipment and high costs cannot satisfy requirements. This paper takes the renovation and transformation of Song Long Pumping Station as an example, analyzes the effect of using large double-speed salient pole synchronous motors. It offers a comparative analysis of the energy-saving benefit, which has three major evaluation indexes： device efficiency, unit energy loss and the benefits. The related research results can be used as a reference in the renovation and transformation of pumping stations.
