110kV数字化变电站二次部分设计

ABSTRACTElectrical secondary part design is part of a measuring circuit,protect circuit andcontrol circuit design,mainly includes the quadratic function of the components are asfollows:measuring instrument,communication transmission system,the equipment,automatic and remote communication equipment,etc.Electrical secondary part designis an important and indispensable link in the design of substation,the rationality of thedesign of secondary to ensure the safety of substations,stable and reliable runningplays a very important role.Substation monitoring system with remote sensing,remote communication,remote adjustment and remote control (hereinafter referred to as the "four control")and other remote function.For total station,and a synchronous device of the clockcorrection for fashion.Substation monitoring and control system should possess andthe function of data exchange between distant workstations.In general,to completethe total stability,appropriate and adequate monitoring,the influence of the computermonitoring and control system is also irreplaceable.Based on the substation secondary part design procedure specification,part of a110 kV substation computer monitoring system of digital related design work,mainlyinclude:the function of the second part of this substation is analyzed and summarized;The substation secondary part to carry out the overall scheme design;Readmanufacturers provide secondary drawings,familiar with the manufacturer to providethe protection of the equipment model and function;Follow the principle of digitalsubstation computer monitoring and control system configuration,the design of thesubstation computer monitoring and control system.In combination with the practicala drawing of transformer substation,this design shows the need of computermonitoring system network schemes,finally successfully completed the final design.Keyword:transformer substation,secondary design,Computer monitoring andcontrol system
