ABB Drives Power UK's Largest Pumping Station
Six 1250kW ABB industrial drives will be powering the UK's largest pumping station, protecting 700km2 of land in the Cambridgeshire Fens from flooding. The pumping station at Wiggenhall St Germans will protect more than 25,000 properties, businesses, conservation sites and extensive areas of high-grade agricultural land in an area called the Middle Level. Each of the six new pump sets will be able to raise 16.66m3/sec to a static head of 4.25m, giving a total capacity of 100m3/sec. This gives the station the capacity to deal with extreme events, although in a moderate year it is expected to run no more than three pumps at a time under normal conditions. A system of rotation will be introduced to ensure that the pumps get an equal amount of use. The ABB industrial drives will adjust the pumps to suit a wide range of flows. Each pump will operate to match the actual flow demand and can respond immediately whenever circumstances change. The pumps will also provide quicker response at ...
