Abstract: In this paper,the design of the system structure and the related communication-service software of the Value-added DataCommunication Network for East China Electric Power System are presented.The key point is the introduction of a communication serverwhich alleviates the master station's communication-load, and implementS the transp arent call among diffeent network protocols. Furthermore,the National Application Layer Protocol for Real Time Data Communication in Power System is extended,and the access of master stationsusing various application protocols is also provided.
