The Design Of Remote Monitoring System Based On Vpn In Wind Power Farm

This thesis based on the HECIC Energy Co., Ltd. in Hebei Province studied the remote monitoring systom aim at the following problems: the production information of wind power farm can not be managed centralized, poor data consistency, data can not be shared, and so on. Mainly studied the overall design, network Formation, data acquisition,Web monitoring of the remote monitoring system. In the process of specific design, according to the research foundation of information security technology and the actual needs of project,a network information security system based IPSec VPN is adopted which assures the safty of the data information; at the same time, the use of standardized OPC technology makes the whole system easy to exchange data and makes the system integration facilitated; Finaly, Web remote real-time monitoring system is implemented based on real-time data access database, ActiveX control, as well as multi-threaded synchronization data processing.
