摘要
我国很多海岛地处偏远,电网很难达到,为解决海岛的用电用水问题,提出了风力发电—抽水蓄能—海水淡化综合系统。建立了系统的数学模型,并对系统进行智能控制,搭建了控制系统硬件平台,提出了智能控制策略,利用VC#2008软件建立了可视化的主控平台,将系统的数据采集、数据检测、控制、数据后处理、数据报表打印等集成在一个交互平台。利用该控制系统可以对风力发电—抽水蓄能—海水淡化综合系统进行实时监测,并通过对实时数据的处理判断系统的运行状态,对综合系统进行智能调度,确保了综合系统运行的高效性和可靠性。将该系统用于海岛,能充分利用当地丰富的风能资源解决海岛用电用水的问题,通过对其进行智能控制,可以实现整个系统的无人值班。
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.
