Research Of Substation Intelligent Monitoring And Diagnosis Based On LabVIEW Platform

The important equipment,such as substations transformer winding, busbar joints, high voltage switching connector and power cable connectors, easily act together to cause serious short-circuit for its insulation aging or excessive contact resistance heating. More seriously, it may cause large area fires and power outages, even great economic losses and serious social impact. So the temperature data monitoring substation equipment is quite essential.This topic is taken based on the United States IN virtual instrument LabVIEW development software, mainly based on its simple operation, high reliability, good performance, human-computer interaction design a set of graphicalinterface control substation intelligent temperature monitoring and diagnosis system platform.The topics elaborated detailed the substation intelligent temperature monitoring and diagnosis system platform design, completed the main design of the human-machine control interface based on LabVIEW, which included the serial communication interface, interface landing, monitoring curve shows, database storage, data monitoring alarm in the master-control interface and other system function, for example, its interface of the Web publishing sharing. The topic also explained the design of system platform for substation equipment external temperature data acquisition, which included the intelligent temperature monitoring system platform complete the lower data acquisition receiving its data interface through a set of data communication protocols, and designed the system platform external interface RS485-USB circuit,which can pass substation lower temperature data collected by RS485-USB circuit transmission to the system platform.
