The Application Of OPC Technology In Demand Side Management Distributed System

Demand side management system which integrated all kinds of techniques above also has been developed rapidly. Owing to great varieties of venders and all sorts of different hardware, the functions of demand side management system have been enriched gradually.However, each vender has not used unified transport protocols, so that devices' communication between different venders is difficult, and that makes great hidden trouble to system maintenance and update.In this paper,OPC (OLE for process control)-criterion at industry field and supervise control system of substation are researched deeply, aiming at the existent problem of demand side management system, the thesis puts forward a case which introduce OPC in the substation supervise control system. Thanks to introduce OPC (OLE for process control), the paper has solved the sharing problem of real time data of different devices, At the same time, two system constructions of B/S and C/S were discussed and B/S and C/S complicated substation supervise system which bases on OPC technique was brought forward. The paper gives concrete design and makes the key part -OPC sever and OPC client come true.
