| Popis: | The multi-type pump configuration equipped with one invert scheme is suitable for the system to operate over a wide range of flow and head at different time periods. Its optimization may be the result of relatively low regulation capability. As a result, a synchronous switch control model was adopted to overcome this defect and to save further energy operation of the pump system. The hardware of synchronous switch control could be achieved by a simple logic control circuit which could be easily programmable and a phase discriminator control circuit which could eliminate the impact current. The software of synchronous switch control could be achieved by the minimum shaft power scheduling model group based on every type pump as variable-speed pump could calculate the optimal operation condition and the minimum switch number could ensure the optimal control regulation scheme. In conclusion, the single invert with synchronous switch control technology was used in an energy-saving reconstruction project of a circulating pump station; it could achieve the gain almost as same as the two invert scheme with the payback time almost the same as the single invert with pony pump scheme. Such is a particularly high quality and reasonable price scheme. |
