500kV南桥变电站在国内和国际上首次采用瑞士ABB提供的P13/42系统,三年来的运行经验证明,该系统结构灵活、运行可靠、维修方便和功能完善。P13/42系统使用了P10可编程语言,即应用先进的微机技术使系统运转速度提高和编程灵活方便,因此在在线监控系统中具有很强的生命力。笔者在实际工作中,感到搞清该系统的工作原理,特别是数据传输原理对促进我们的工作有所裨益。现将初步研究分析结果阐述如下供参考。
The 500kV Nanqiao Substation is the first in China and internationally to adopt the P13 / 42 system provided by Swiss ABB. The operating experience over the past three years proves that the system is flexible in structure, reliable in operation, easy in maintenance and perfect in function. P13 / 42 system uses the P10 programmable language, which means the application of advanced microcomputer technology to make the system running speed and programming flexibility and convenience, so online monitoring system has a strong vitality. In the actual work, I feel that I can get a clear understanding of the working principle of this system. In particular, the principle of data transmission is beneficial to our work. Now the preliminary analysis of the results set forth below for reference.
