摘要
针对变电运维过程中故障信息识别不精确、识别效率低等问题,文章采用基于传统运维安全处理系统,设计出先进的多层安全防护系统;通过利用压缩感知和贪婪匹配等数据融合算法对电力信息识别进行改良,引入超声波信号网格定位方法对故障点进行定位;结果是在硬件与软件方面通过层次化设计进一步提升系统效率;试验表明,所设计的系统比传统电力信息系统拥有的精确度高,故障检测识别率高达100%,时延为27 ms。
Aiming at the problems of inaccurate identification of fault information and low identification efficiency in the process of substation operation and maintenance,the method adopted in this paper is based on the traditional operation and maintenance safety processing system,and an advanced multi-layer safety protection system is designed.The power information identification is improved by using data fusion algorithms such as compressed sensing and greedy matching,and the ultrasonic signal grid positioning method is introduced to locate the fault point.The result is to further improve system efficiency through hierarchical design in terms of hardware and software.Experiments show that the designed system has higher accuracy than traditional power information systems,with a fault detection and recognition rate of up to 100%,and a delay of 27 ms.
