摘要
传统的电网调度故障诊断系统在诊断故障元件时,错误率很高,难以满足目前电网调度提出的要求。针对这一问题,引用大数据技术设计了一种新的电网调度故障诊断系统,对系统的硬件和软件进行设计,硬件通过EtherCAT协议设计了应用系统,应用模块和时钟模块,重点设计了诊断器,介绍了诊断器内部MC9S12DP256B芯片的工作性能。根据硬件结构给出了软件流程,包括复位处理、故障元件确定、中心模块分析和结果反馈四步。与传统系统进行了对比实验,设定15 min为临界点,分析两个系统的错误率,结果表明,随着时间的增加,传统系统的错误率越来越高,最后高达44.44%,本文研究的系统错误率仅为3.85%。
The traditional fault diagnosis system for power grid dispatching has a high error rate in the diagnosis of fault components,which is difficult to meet the requirements of current power grid dispatching.To solve this problem,a new fault diagnosis system for power grid dispatching is designed by using large data technology.The hardware and software of the system are designed.The application system,Application module and clock module are designed by using EtherCAT protocol.The diagnostic device is designed with emphasis.The performance of MC9 S12 DP256 B in the diagnostic device is introduced.The software flow chart is given according to the hardware structure,including reset processing,fault component determination,center module analysis and result feedback.Comparing with the traditional system,the error rate of the two systems is analyzed by setting 15 minutes as the critical point.The results show that the error rate of the traditional system is higher and higher with the increase of time.Finally,it reaches 44.44%.The error rate of the system studied in this paper is only 3.85%.
