Abstract
In order to give out the advice for power grid to manage the real-time current-carrying capacity of power cable and improve the utilization of power cables,the real time current-carrying capacity evaluation system is constructed for high voltage power cable including the terminal to monitor real time environment parameters,GPRS to transmit the environment data and the main computer.First of all,the real-time environmental parameters monitoring system consisting of DS18B20,wind sensor,soil temperature and humidity sensor,illumination sensor and STM32 embedded MCU is designed,realizing real-time collection of the environmental parameters such as ambient temperature,soil moisture,soil temperature,ambient wind and light,and so on.The environment data is transmitted to the main computer by GPRS data transmission module.By using the computer combing VB6.0 and ANSYS,the software is programmed to calculated the temperature and current-carrying capacity of high voltage power cable.Some functions,such as database storage of power cable size,window mode to show the arrangement of cables,real-time monitoring and show of environment parameters and on-line calculation of real-time current-carrying capacity,are realized in the system.Studying the real-time current-carrying capacity system of high voltage power cable is of great significance to rationally arrange the load of the cable in real time.关键词
