Substation Auxiliary Equipment Integration Of Centralized Monitoring System Of Research And Development

With China’s rapid economic and social development， the social demand forelectricity and the degree of dependence is more and more big， to speed up power gridconstruction and transformation of the increasingly urgent demands. Substation forpower transmission line physical connection point， its safe and economic operation ofpower system security management has become the core component of. This also onintegrated substation automation level raised taller and taller requirement. Study andestablish the centralized monitoring system of substation secondary equipment isunattended (or fewer people on duty) important means， which can greatly improve thesubstation integrated automation level， reduced chance of accidents， accidenttreatment and shorten recovery time， make more stable， reliable operation ofsubstationAuxiliary equipment of transformer substations concentrated monitoring integratedsystem is the technology intensive， a variety of professional and technical cross eachother， coordinate system. It is established in the computer hardware and softwaretechnology， data communication technology developed on the basis of. It is integratedsubstation in addition to a two device， all auxiliary equipment. Substation auxiliaryequipment centralized monitoring integrated system and functional module by differentconfigurations of the single-chip microcomputer or， uses the centralized structure，through the network， bus microcomputer protection， data acquisition， control of thesubsystems together， form an integrated system.Substation secondary equipment centralized monitoring integration systemintegration of temperature measurement system， anti-theft alarm system， fire alarmsystem， cooling system， arc suppression coil monitoring， emergency lightingsystem， leakage current on-line monitoring， DC system grounding line device，access control system and video monitoring system， based on the ARM7single-chipLPC2131chip design collection each digital signal and the analog input portion istransmitted to the CPU minimum system for logic operations， processing， intelligent recognition， through the CPU minimum system by digital output part to control therelay to achieve the remote control function， finally using ModBus communicationprotocol based on single layer software design completion of each system the dataacquisition， the ultimate solution to the various systems of decentralized operation，form the monitoring information unified transmission standard.Auxiliary equipment of transformer substations concentrated monitoring integratedsystem， finally realizes the220kV and above substation auxiliary equipment operationmonitoring， improve the video monitoring system， server and camera intelligentinspection， according to user defined requirements (frequency， places) automaticswitching pictures， to the operation staff provide a full range of monitoringinformation， management staff to provide the function of statistical analysis andgenerate various reports， prepare all kinds of operation of substation equipmentinformation upload interface specification and communication protocol， for theprovince of a unified and standard provides the basis to realize substation auxiliaryequipment standardization， standardization， which can greatly improve the powersupply enterprise production management level， to promote faster and betterdevelopment of power supply enterprise.
