William Livoti of WEB recommended that power plants assess their pump requirements and consider variable speed drives to reduce energy consumption. He cited the advantages when handling off peak loads. A specific example was given for the VFD saving with cooling water makeup pumps. The number of pumps and potential savings is substantial.

Power Plant Pumps Webinar - Hot Topic Hour September 11, 2014
For power plant pumps, discussion was the ability of variable speed drives to potentially save power companies billions of dollars. There is evidence that power plants can use this technology and avoid installing cooling towers to meet the 316(b) water intake rules.

ACS 1000 variable speed drives improve efficiency of CHP power plant
The boiler feed-water pumps at Helsinki Energy‘s CHP plant were controlled by wound-rotor motors with slip recovery control system. In order to reduce maintenance costs and further improve the plant‘s efficiency, the pump drive systems were upgraded with four ACS 1000 variable speed drive systems from ABB (each rated at 4500 kW).

VFD at the Hainan Yangpu 220 MW GTCC
This paper discusses the application of variable frequency drives (VFD) in the high-pressure water feeding system of boilers serving Units 11 through 13 of a combined cycle section of the Hainan Yangpu Thermal Power Plant. The article is written by the plant engineer responsible for the operation and maintenance of the system. In the first year of operation there were severe problems with the valve caused in part by inability to measure the outlet pressure of the BFP system and it was determined that a solution lay with replacing the hydraulic coupling with VFD.

VFDs can make a big difference in optimizing pump energy consumption in cooling tower makeup
William Livoti writing in “Empowering Pumps" discusses some of the potential regulations which will force recycling of cooling water. He says that power plants need to assess their pump requirements and consider variable speed drives to reduce energy consumption. He cites the advantages when handling off peak loads. A specific example is given for the VFD saving with cooling water makeup pumps
