基于云模型和模糊Petri网的电力通信网络系统可靠性评价与管理策略

针对复杂电力通信网络系统的系统可靠性问题,本文提出了一种新的基于正态云和模糊Petri网相结合的系统可靠性评估模型。从分析设计阶段、建设实施阶段和运行维护阶段提出了可靠性管理的相关策略,对电力系统通信部门来说,进行通信系统各阶段可靠性管理具有十分重要的意义。

基于模糊层次分析的电力通信系统网络安全评估指标体系构建

针对当前电力企业通信系统网络的指标体系冗余难以量化风险不确定性问题,采用模糊层次分析方法,从通信设备安全、通信网子站安全、业务运行与管理安全、员工操作安全4个方面构造了模糊判断矩阵,采取三角模糊函数确定指标项的权重,建立了科学合理的通信网络安全指标体系。与传统的安全指标体系构建方法相比,该方法能够克服通信网络风险单一定量分析缺点,实现定量与定性相结合的模糊化指标权重确定,为提高电力通信网络的安全风险评估准确性提供了新方法。

Design and Implementation of a Single-Phase Energy Meter with SMS Controlled and Monitored Recharge Capability

The Nigerian power sector is faced with poorly organized billing and consumer relations management. Tariff billing and collection has been a big problem in some community in Nigeria even with the introduction of prepaid meters. The process of payment is cumbersome and stressful as consumers have to go and pay in banks and then take tellers to power utility office to confirm their power bills payment before they can recharge their cards. The major purpose of this work is to design and implement a convenient, cashless, automated and transparent electricity metering, billing and payment system. This project combines the power electronic meter with a communications network which in this case is a GSM （global system for mobile） network. Remote electricity billing is a unique concept, in which the electricity board can collect the consumed units＇ data from consumer on mobile phone using GSM network. A unique property of this system is that, the electricity board can disconnect or reconnect consumers from remote location through the mobile phone. As this project works on GSM network, the system can be controlled from any part of the country.
