电力电缆在线载流量预测报警系统的开发研究

Research on forecast and alarm system of ampacity on-line for power cable

为了在线预测电力电缆载流量,依据载流量的计算原理,应用MCS-51单片机和VB开发了温度在线监测采集板,并阐述了硬件结构、软件设计。实验证明,该系统运行良好、精度高,能满足电力系统运行的需要。

The sampled-data board of temperature monitoring on-line was developed by using the microcomputer typed MCS-51 and VB software based on the calculating principle of ampacity in order to forecast current carrying capacity of power cable, and its hardware structure and software design was also discussed. It was shown that the system can work well with high precision and meet the requirements for electric power system to run safely and economically.
