基于虚拟仪器的高分辨率SoE系统设计研究

事件顺序记录系统可监测电厂事故发生前后的运行状态,其性能直接影响事故分析的及时性和准确性。将单片机实现数据采集的灵活性与LabVIEW的海量数据分析处理能力相结合,研究巨型开关量SoE系统的硬件与软件设计。数据采集和数据分析功能的分离,大幅降低了硬件设计的复杂程度,提高了SoE系统的分辨率,为建立SoE电网故障分析系统提供一种新的设计思路。

Study on the Design of SoE System with High Resolving Capability Based on Virtual Instrument

Sequence of Event(SoE) system can monitor the running state of power plants when accident happens,the performance of SoE directly affect timeliness and accuracy of the accident analysis.Based on combining the agile of data acquisition with single chip computer with the analysis capability of substantive data with LabVIEW,the design of hardware and software of a SoE system is studied in this paper.Owing to the separate function of data acquisition and data analysis,the complexity of hardware design is reduced enormously,and the resolving capability is improved greatly,at the same time,a new way to design electric network malfunction analysis system is provided.
