The Design And Application Of Oil Field Power Grid Failure Monitoring System

At present,with the progress of science and technology,users of the power supply reliability,stability,power quality put forward higher requirements,etc.How to monitor the whole power grid and store large amounts of operation data,how to effectively use fault wave record data auxiliary diagnosis for power grid failure,become an important research topic in daqing oil field power grid at present stage.This article first analyzes the present situation of fault monitoring system of daqing oil field,according to the actual oilfield network is put forward by a master station,station and Ethernet monitoring system,signal acquisition system pair can stand electric parameters,implementation of oil field power grid faults and overall health for the purpose of monitoring.To take advantage of the fault wave record data grid fault monitoring and auxiliary diagnosis,this paper designed to signal acquisition and communication network composed of oil field power grid fault monitoring station system,sub station is based on the current and voltage sensor signal processing,realize the voltage and current signals such as synchronous distance set.Acquisition of the signal can through the communication network,uploaded to the master station information management system,to provide users with visual monitoring of power grid operation services,to provide supplementary help to power grid fault diagnosis,at the same time users can quickly in the information management system for the calculation of active power,etc.In order to collect real-time signal station system electric parameters,this paper based on the data collection and measurement,through the sensor and MCU about advantages and disadvantages of contrast,best selection;Then completed a system of communication networks and signal conditioning module hardware design.System,the main aspects in this paper,the overall idea of the software and each module for process optimal design,the system will measure and calculate the data for display,processing and analysis functions.Using Delphi software platform,developed a PC user interface,designed the interface between PC and each module,has realized the monitoring equipment and computer communication,make the master station system for grid circuit of electric parameters and running status of remote measurement function,and realize power,frequency,power factor and other parameters are calculated.Finally,the article will design the system of the trial to the actual production of oilfield network is,through the study of the collection and analysis of oil field power grid failure data,and carries on the contrast test and fault situation,verify the correctness and practicability of the system.
