| Abstract: | This paper introduces practical new techique for secondary pump station in water plant withVVVF controlled by PLC in the way of direct program, in which controlling target is set on the most disadvantagepiont and hour after hour stastics model takes the place of feedback loop. Such a system turns out to be successfuldue to simple characteristics with apparent result in energy saving and economic profit. |
