Research On The Technique Of Communication Network In The Substation Automation System

Substation automation technology has been widely used in MV/LV substation system in China since 90's. Now it has been development to HV/UHV substation system. With the gradual improvement of the substation automation technology, it brings some new demands on communication network in substation. This dissertation deals with some popular problems communication network in the substation automation system. It researches communication network technology in the substation automation system basing on my projects, and solves some problems the substation automation system faces. It contains the content as fellows:1. Research the TCP using in the communication network of substation automation system. This dissertation made a thorough research on TCP, and provides it's using mode in substation automation system. This dissertation also involves the corresponding software in CSC2000 system, and tests the performance of TCP in CSC2000 system.2. Research the application of 100M Ethernet in substation automation system, and provide a new network configuration of substation automation system base on 100M Ethernet.3. Realize the interface between MC68360 and SJA1000 using FPGA, and discuss the application of FPGA in substation automation system.4. Research the IEEE1131, and discuss the actuality and the future of programmable concept used in substation automation system.
