南水北调宝应抽水站流量定线方法探讨

Discussion on Baoying Pumping Station flow aligning method in South-to-North Water Diversion Project

本文以宝应抽水站为例,对临界扬程抽水站流量定线方法进行了研究。鉴于宝应抽水站扬程处于低扬程和高中扬程的分界处,根据实测流量资料,按照规范给定的低扬程和高中扬程抽水站流量定线方法,分别确定了该站的流量关系曲线,并对定线结果进行了检验和精度评定。结果表明两种定线方法均可行,且定线精度较高。通过本文研究,丰富了宝应抽水站的流量定线方法,为处于扬程分界处的抽水站流量定线提供了参考案例。

In the paper, Baoying Pumping Station is regarded as an example to study critical head pumping station flow aligning method. Since the head of Baoying Pumping Station is located on the boundary between low head and high-medium head, flow relationship curves of the station are respectively determined according to measured flow data and in line with flow aligning method of low head and high-medium head pumping station given in the specification. The aligning results are tested, and the precision is evaluated. The results show that two aligning methods are feasible with higher aligning precision. Flow aligning method of Baoying Pumping Station is enriched through the study in the paper, thereby providing reference cases for pumping station flow alignment located in the head boundary.
