| Abstract: | By analyzing the volume of circulating water in turbine power generators in different seasons and under different operating loads in the case of a typical example, a comparative analysis has been made with different water circulating pump updating schemes, and a dual-speed control energy-saving updating scheme is therefore suggested for water-circulating pumps. The technical economy of the dual-speed energy-saving updating of water circulating pumps is discussed from the fact that there are different prices for the same energy conversion at different power plants. |
