Design Of Microcomputer Monitoring System Of110kV Photovoltaic Grid Substation Based On Kingview

In this paper,based on a study of110kv substation, considering the current situation ofthe development of substation computer monitoring technology at home and abroad,according to the requirements of substation monitoring and control system function, putforward the use of building roof placed photovoltaic array combining photovoltaic andsubstation, and using kingview110kv substation computer monitoring system software isdesigned and developed.First combines the development trend of substation computer monitoring system at homeand abroad, the system structure is divided into centralized, distributed, hierarchicaldistributed, after the comparative analysis to establish the hierarchical distributed monitoringand control system structure, clear the function of each layer structure distribution andprinciple, put forward the idea of photovoltaic power generation system connected to thetransformer substation station electricity as well as the scheme design, form the overallframework of substation computer monitoring system.Secondly, set up with RS485and the two big main Ethernet substation communicationnetwork and realize the real-time and reliable data transmission.Again, has been clear about the substation computer monitoring and control systemsoftware design principles, established after analysis and comparison with modular design, themodule can be divided into system management module, user security management, alarmmodule, graphic display module, data processing module, the sequence of events recording,report printing, manual control module, database management module, data communicationmodule, and photovoltaic system module, etc. Finally through study of kingview software, design the man-machine dialogue andsystem operation monitoring platform, complete the function of each module of graphicconfiguration.
