Design Of Monitoring System For E37 Substation In Daqing Petrochemical Company

With chemical enterprises require to maximize the efficiency of the economic situation,reduce non plan shutdown times, for power system security and reliability requirements more and more high, to change the requirements of substation comprehensive automation degree also increased gradually. To ensure that the power of the safe and stable running of the supply,this paper for Daqing Petrochemical Company chemical plant E37 substation traditional central signal disc state monitoring, light plate alarm of low accuracy and poor sensitivity, and the inability to accurately complete the switching operation rehearsal, the to transformation research.In this paper, the electrical equipment of the automatic fault detection is studied, using sensors to collect digital and analog data acquisition card, analog digital conversion and data collection, use the Labview software programming, and finally display the data and judgment in the host computer, when the measured value exceeds the preset range, will activate alarm system alarm and fault prompt, display in real-time alarm window, for the protection of the substation main transformer equipment and various bus, ensure the substation monitoring sensitivity and accuracy of the system, improve the management level of the electric power system operation.This is the two chemical factory of Daqing Petrochemical Co E37 substation design a running state monitoring system. By using the new Kingview software, design the main interface of system, complete the connection with the main interface of monitoring data,monitoring the state of substation switching operation, can be normal and record the corresponding real-time, real-time curve, historical trend curve data, monitoring of the electrical instrument at the same time, voltage, current, power and other operating parameters can be displayed visually.
