Design and Simulation of IEC 62056 Electricity Meter Model

This paper gives a brief introduction of IEC 62056 standards at first and then discusses the details about how to build the meter function model and the data model according to IEC 62056 standards.Finally it is described how to realize the IEC 62056 electricity meter by a simulation instance.

IEC 62059 Standards' Application in Reliability Prediction and Verification of Smart Meters

This article introduces the current situation of the smart then describes the relationship of meter reliability characteristics meter＇s reliability and the failure mechanisms at first, and combined with its Bathtub Curve. It also introduces both the feasible failure tree model for meter lifecycle prediction based on actual experiences and meter reliability prediction methodology by SN 29500 norms based on this model. This article also brings forward that it is necessary that the ＂Learning Factor＂ shall be adopted in meter reliability prediction for new materials, new process, and customized parts by referring to GJB/Z299C. Thereafter, this article also tries to apply IEC 62059 and JB/T 50070 to introduce the feasible method for the lifecycle prediction result verification by accelerated lifecycle test. Furthermore, the article also explores ways to increase the firmware reliability in smart meter.

智能调度故障操作票生成系统研究

由于传统电网调度操作票系统应用环境较为固定,难以满足多情景下的操作应用需求,故提出采用IEC61850标准构建变电站应用体系,提高系统的扩展应用性能,并将变电站的拓扑关系以树状结构描述,提高变电站设备之间的关联性。目前主要研究正常倒闸操作票自动生成,但是调度人员处理事故完全靠经验,直接口头下令,人为失误会导致更严重的停电后果,所以对故障操作票的研究很有必要。文中研究的故障恢复操作票系统主要分为故障定位、故障恢复供电路径和故障操作票生成三部分。以上述处理结果为基础,采用蜻蜓算法中的小波包灰度矩神经网络精准定位操作故障,然后迅速隔离故障,最后,采用二进制差分算法寻找非故障供电恢复的路径,并通过实际案例完成故障操作票的生成。
