110kV Digital Substation Design
Abstract
With the progress of economic construction, the construction of China's power industry obtained the rapid development, the transmission capacity of power system is enlarged continually, power network structure is more huge and complex, promote the as a mode of substation of power system is an important part of the rapid development. The digital substation is becoming more and more important in the power grid construction in China, with its advantages of high performance, high security, high reliability and high economy.
The status of the digital substation and era background is discussed in this paper at first, and then the concept and advantages of digital substation are analyzed, the ICE61850 communication standard and GOOSE network are introduced next.Then this paper designs the network structure of digital substation, discusses the station control layer, middle layer and interlayer structure;and finally it takes a real 110 kV digital substation as an example, expounds the structure of the digital substation, principle and learning in the operation of the various situations and the design of digital substation proposed a kind of feasible scheme.
This paper has 13 figures, 8 tables, 24 references.
