Study On The Optimizing Configuration Program And Debugging Technology In The Intelligent Substation

This thesis mainly introduces the theory of high voltage equipment of intelligent substation. It especially introduces and studies the intelligent allocation scheme and debugging technology of intelligent substation.The intelligent substation, included of substation level, equipment level and station level. The substation level is composed of high voltage equipment and intelligent component,merging unit, terminal unit,to achieve the function of allocation, exchange, transmission and measurement, control, protection, metering, status monitoring. The intelligent high voltage equipment is composed of intelligent transformer,intelligent switching devices, electronic transformer and else. This paper also clarified the definition and principle of intelligent component, merging unit, terminal units,debugging technology.The thesis is also based on the analysis of the construction of the fist500KV intelligent substation, which is called Changli500KV intelligent substation. It analyzes and compares different implementation ways of intelligent switchgear and transformer, and determines the intelligent configuration scheme.By the functional integration,all kinds of intelligent monitoring device provided an intelligent system unit;the main transformer composed of the equipment and intelligent integrated components.Based on a comprehensive analysis of the core technology and intelligent configuration scheme ofhigh voltage equipment of intelligent substation, and the real debugging of Changli, the thesis studies the debugging technology of intelligent substation. The debugging of intelligent substation is totally different from conventional substation. Intelligent substation requires an additional integrating test between the factory test and field test. It improves the efficiency of the overall debugging. It will be very helpful to the debugging of other intelligent substations in the future by analyzing the problems and developing the corresponding solutions during the debugging.
