Many islands in our country are far away where power supply by the grid is too difficult.To solve the problems of electricity and freshwater uses in these areas,a hybrid wind-pumped storage-desalination system was brought forward recent years.In the present work,a mathematical model of such hybrid systems was developed and a hardware platform of control system was built.The focus was to study intelligent control of the system and formulate a practical control strategy.By using VC 2008,a visual interactive platform was established as a central control for data collection,data examination,control,data post-processing,data report-forms,data mimeograph and so on,and it was applied to real-time monitoring of the hybrid system.Through analysis of the real-time data and estimation of the system′s operating state,intelligent dispatching schemes have been formulated to assure efficiency and reliability of system operation.The system,if built on an island,can make use of the local abundant wind energy and the adoption of intelligent control system provides the island with self-service of electricity and freshwater supply.
