Examples
- The sa9904b , produced by sames company , is a three phase bi - directional energy / power chip and completes the measurement of rms voltage , rms current , powe , energy , power factor and frequency as the kernel of detecting unit
本系统采用sames公司的三相双向电能功率芯片sa9904b作为测量单元的核心来完成电压、电流、功率、电能、功率因数和频率的测量。 - Therefore it comes true the on - line adjusting , real - time control and so on . it sames as real locale . the software of logic protect ( include electric logic ) and control includes some usual algebraic and operation model of thermal control and logic operation of logic protect . it adopts foxboro ' s dcs as a example , so we configuration via filling table , user only define i / o condition , fill certain operation variable , and name logic variable . the software offers a friendly user ' s interface , personnel can compile and modify the control and logic program , change the value of logic and control variable conveniently , attach themselves to run , debug and control the set , not need to know about the inside of the old programs deeply . so the configuration software offer a flat that control engineer can attend to the structure of control loop and logic protect ( include electric logic ) , not but to handle complicated program
它以foxboro的dcs控制系统为主要参考模式，采用填表的方式进行控制组态，用户只需定义i / o条件、填写具体的运算变量名、逻辑变量名即可。本软件为建模人员提供了一个友好的用户界面，使建模人员在建模时不必对模块内部的控制、逻辑程序有很深的了解就可以方便的对其进行编写和修改，实时改变各逻辑和控制变量在数据库里的值，参与运行和调试，从而实现对机组的控制。因此，本组态软件提供的这样一个平台，让控制工程师能集中精力于控制回路及逻辑保护（包含电气逻辑）的构成，而不必拘泥于一些具体而烦琐的程序操作。 - This paper aims at the request of distribution automation and the disadvantages of existent ttu products and puts forward a scheme of ttu design : dsp ic tms320lf2407a of ti ltd . is chosen as a controller because of its high performance ; a three - phase power / energy ic developed by sames ltd . is used as a measure module to simplify the hardware circuit and software program ; the embedded modem and rs485 / rs232 mode communication interfaces are designed to make the data transfer more flexible and effective ; the 101 communication protocols of international electric power standard are adopted to improve its compatibility
本文针对配电自动化的要求及现有ttu产品的不足，提出了一种基于dsp的配电变压器远方终端单元的研制方案：微控制器选用ti公司高性能定点dsp芯片tms320lf2407a ；使用sames公司推出的三相电能计量芯片sa9904a作为测量模块，简化了硬件电路和软件编程；采用siliconlaboratories的嵌入式modem 、 rs485 rs232等多种通信方式，使数据传送变得灵活、高效；为了提高设备兼容性及通用性，通信协议采用国际电力标准101规约。
