An experimental Substation Automation System based on Fieldbus and PLC;

Application of wireless networks in substation automation system;

This paper presents a substation automation system based on Fieldbus where PLC is used as the control unit.

Design of communication system of substation automatization based on Agent;

With the development of micro-electronics technology、computer and communication technology,the substation automatization technology also develop quickly.

Summarization of typical design model for northeast comprehensive automatic substation;

As the necessity of accident responsibility identifying which because of exception in automatic equipment of automatic substation,a design method about digital information recorder recording communication protocol of novel automatic substation is discussed.

Considering the developm ent of communication network,the com munication network architecture based on the embedded Ethernet technique for EHV substation autom ation system is proposed.

By combining multim edia technology and TCP/ IP based network technology with the substation autom ation,a new idea of substation multim edia automation system is proposed to realize digitized transm ission of m ultimedia information between master station and substation.

Three factors are presented that are of influence on the application of multim edia technology to substation autom ation,which are video information transm ission,the integration of m ulti- modality input and engineering funds.
