摘要
针对各传统箱式变电站监测装置之间互操作性不良以及预警预测准确率低的问题,提出一种箱式变电站智能电子设备设计方案。该方案基于STM3F4和S3C2440A处理器构建平台,采用趋势滤波算法完成高速数据处理,并通过建立的模型完成电力负荷预警及温湿度预测,最后在以太网通信方式下借助IEC61850协议完成数据封装,实现信息交互。实验结果表明,该方案提高了设备之间通信互操作能力和电力负荷预测的准确度。
In allusion to problems of poor interoperation of monitoring devices of traditional box-type substations and low prewarning accuracy rate, this paper presents a kind of design scheme for intelligent electronic equipment in box type substation. Based on STM3F4 and S3C2440A processors, this scheme constructs a platform and uses trend filter algorithm to complete high speed data processing. It can complete power load pre-warning and humiture prediction by means of the established model and finish data packaging with the help of IEC 61850 protocol under the mode of Ethernet communication so as to realize information interaction. Experimental results indicate that this scheme has improved communication interoperation between devices and accuracy of power low prediction.
