Ding Zhou Pangcun 110kV Substation Digitization Of Key Technology

With microelectronics technology, network communication technology and the development of information technology applications, especially its application in power system, makes the traditional substation to develop in the direction of integration, automation, integration. IEC61850 standard come on stage and is widely used, make between different manufacturers of equipment to realize the mutual communication, mutual operation, data sharing of resources, saving the cost of the construction of the substation, improve the utilization rate of the equipment and convenient for the system upgrade expansion, reduces the maintenance staff work strength. Digital substation system put into use, abandoned the traditional electrical communication mode, use the digital mutual inductance equipment and combined unit for data acquisition, adopting high speed Ethernet to realize the communication between the equipment and systems and makes the information collection, transmission and processing of the entire digital, improve system reliability and stability. Believe that with microelectronics technology, communication technology and information technology to further introduce, substation will inevitably toward high reliability, stability, easy extensibility and detect direction.This article first introduces the basic concept of digital substation, domestic and foreign development present situation, technology characteristics, main functions, hardware IEC61850 standard protocols, digital system characteristics, then to a pang village, 110 kv substation digitization construction as an example, introduces the design idea, architecture and implementation scheme of digital substation, and the scheme of technical and economic analysis, and according to the specific situation in hebei, the place of pang village, 110 kv substation digitization construction of hebei power grid construction, operational bring far-reaching influence, has higher application value.
