Research On The Secondary System Debugging Technology Of Shuangxi Intelligent Substation

This paper mainly studies the secondary system debugging technology of Shuangxi 220 k V intelligent substation. Through practice, it participates in the acceptance and debugging of Shuangxi intelligent substation. Starting from the three-layer structure of intelligent substation secondary system, the paper introduces the merging unit and intelligent terminal The protection principle and test method of the main protection devices involved in the space layer, and the test method of the remote control parameters of the station control layer.The intelligent substation is developing rapidly at present. The debugging contents of the secondary system are much changed compared with the conventional substation. The acceptance debugging technology is not yet mature. How to debug the secondary substation of intelligent substation with high quality and high efficiency, Power grid construction has important significance and value.With the continuous rise of intelligent substation, intelligent substation structure, composition and related debugging technical specifications are also very popular, intelligent substation secondary system debugging technology also has many areas studied. For example, the analysis of the three-tier structure of the secondary system of the intelligent station, the description of the equipment used by the manufacturers and the exploration of the principle and debugging method of the intelligent station protection provided the powerful development of the intelligent substation. in accordance with.Acceptance of substation commissioning work is to determine whether a new substation can be put into operation a reliable key link, the acceptance process needs to be fully efficient, as short as possible debugging time. As the second-time on-site commissioning personnel in the field debugging work often encounter many problems, such as the process of intelligent substation is a unique new device, debugging method is relatively unfamiliar; spacer layer protection device manufacturers involved in the protection provided The theory is too theoretical, resulting in commissioning personnel need to spend a lot of time to understand and explore; station control layer of the lack of intuitive debugging method, in practice is often asked manufacturers and combined with conventional station acceptance experience, these difficulties will undoubtedly debug the process Bring difficulty will delay the commissioning period. So in the process of finishing the paper more want to combine theory and practice, to write a more practical in the field operation of the secondary system debugging smart technology, and work encountered problems more intuitive to show it.In this paper, the intelligent secondary substation commissioning technology is based on the relevant protection theory and test description proposed by the predecessors. It is simpler, more practical and practical debugging method, which can be more practical. Production line operators to provide a more simple and easy to understand the test principle and debugging methods, but also for intelligent substation debugging technology to provide more valuable experience.
