We are very pleased to introduce the proceedings of the First EAI International Conference on Smart Grid Inspired Future Technologies (SmartGIFT 2016). This was the first SmartGIFT conference, aiming to create a forum for researches, developers, and practitioners from both academia and industry to publish their key results and to disseminate state-of-the-art concepts and techniques in all aspects of smart grids. The 37 scientific participants had many fruitful discussions and exchanges that contributed to the success of the conference. Participants from 12 countries made the conference truly international in scope.

The term “ smart grid ” defi nes a self - healing network equipped with dynamic optimiza- tion techniques that use real - time measurements to minimize network losses, maintain voltage levels, increase reliability, and improve asset management. The operational data collected by the smart grid and its sub - systems will allow system operators to rapidly identify the best strategy to secure against attacks, vulnerability, and so on, caused by various contingencies. However, the smart grid fi rst depends upon identifying and researching key performance measures, designing and testing appropriate tools, and developing the proper education curriculum to equip current and future personnel with the knowledge and skills for deployment of this highly advanced system.

In order to enhance the efficiency and reliability of the power grid, diversify energy resources, improve power security, and reduce greenhouse gas emission, many countries have been putting great efforts in designing and constructing their smart grid(SG) infrastructures.Smart gridcommunicationsnetwork(SGCN) is oneof the key enabling technologies of the SG. However, a successful implementation of an efficient and cost-effective SGCN is a challenging task

2-1 何谓测量放大电路?对其基本要求是什么? 在测量控制系统中,用来放大传感器输出的微弱电压,电流或电荷信号的放大电路称为测量放大电路,亦称仪用放大电路。对其基本要求是:①输入阻抗应与传感器输出阻抗相匹配;②一定的放大倍数和稳定的增益;③低噪声;④低的输入失调电压和输入失调电流以及低的漂移;⑤足够的带宽和转换速率(无畸变的放大瞬态信号);⑥高输入共模范围(如达几百伏)和高共模抑制比;⑦可调的闭环增益;⑧线性好、精度高;⑨成本低。 2-2 图2-2a所示斩波稳零放大电路中,为什么采用高、低频两个通道,即R3、C3组成的高频通道和调制、解调、交流放大器组成的低频通道? 采用高频通道是为了使斩波稳零放大电路能在较宽的频率范围内工作,而采用低频通道则能对微弱的直流或缓慢变化的信号进行低漂移和高精度的放大。 2-3 请参照图2-3,根据手册中LF347和CD4066的连接图(即引脚图),将集成运算放大器LF347和集成模拟开关CD4066接成自动调零放大电路。 LF347和CD4066接成的自动调零放大电路如图X2-1。

铝电解电容器:详细介绍原理,应用,使用技巧 电容器(capacitor)在音响组件中被广泛运用,滤波、反交连、高频补偿、直流回授...随处可见。但若依功能及制造材料、制造方法细分,那可不是一朝一夕能说得明白。所以缩小范围,本文只谈电解电容,而且只谈电源平滑滤波用的铝质电解电容。 每台音响机器都要吃电源─除了被动式前级,既然需要供电,那就少不了「滤波」这个动作。不要和我争,采用电池供电当然无必要电源平滑滤波。但电池充电电路也有整流及滤波,故滤波电容器还是会存在。 我们现在习用的滤波电容,正式的名称应是:铝箔干式电解电容器。就我的观察,除加拿大Sonic Frontiers真空管前级,曾在高压稳压线路中选用PP塑料电容做滤波外,其它机种一概都是采用铝箔干式电解电容;因此网友有必要对它多做了解。 面对电源稳压线路中担任电源平滑滤波的电容器,你首先想到的会是什幺?─容量?耐压?电容器的封装外皮上一定有容量标示,那是指静电容量;也一定有耐压标示,那是指工作电压或额定电压。 工作电压(working voltage)简称WV,为绝对安全值;若是surge voltage(简称SV或Vs),就是涌浪电压或崩溃电压;,超过这个电压值就保证此电容会被浪淹死─小心电容会爆!根据国际IEC 384-4规定,低于315V时,Vs=1.15×Vr,高于315V时,Vs=1.1×Vr。Vs是涌浪电压,Vr是额定电压(rated voltage)。
