摘　　要：针对电网运行过程中状态监测和故障预测、检测和定位的需求,研究了电网运行故障监测技术,提出了基于嵌入式系统对电网工作参数采集、运行状态监测和故障检测方案.详细阐述了电网中运行参数监测的核心技术,采用傅立叶变换在解决信号滤波的同时,也对信号的频率进行采集.在此基础上,设计了电网运行中短路故障的检测方案,并给出了详细实现措施.利用MAT-LAB仿真测试,结果表明,本文所设计的方法对电网参数采集准确,精度高.In view of the electrical network working process in the state monitor and the failure predi- cation, examination and localization demand, has studied the electrical network working failures monitor technology, and then proposed the electrical network parameter gathering, the running status monitor and the failure detection plan based on the embedded system. Elaborated in detail the monitor core technologies to the electrical network working parameter, during solution signal filtering with the Fourier transformation, has carried on gathering to the signal frequency. Based on this, has designed the short trouble examination plan in the electrical network working, and gave has realized the measure its detail. Using the MATLAB sim- ulation test, the result indicated finally, the method designed in this paper is accurate to electrical network parameter gathering, the precision is high.
