Research And Design Remote Voltage Monitoring System Based On GPRS

Along with the economy expeditiousness development of our country, the improvement of electrical energy quality has already been the most important content in the national policy. Voltage is not only one of the most index of electrical energy quality, but also it proves the electrical power system level. In the case of low electrical power automatism management in our country, and in order to improve voltage monitoring data veracity,authenticity,integrality, and reduce the time of making statistics and record data efficiently for administrators, increase the analysis, and raise the management level of power supply voltage efficiently. We designe a set monitor voltage system based on the GPRS, which has actual use value.By compassion of scheme, requirement and function analysis, we use the GPRS module which has AT commands to control agreement and can achieve remote data transmission. And we compute virtual voltage value based on AC sampling theory that is in existence, and then we design a set monitor voltage system, which can real-time or timing compute values. The RTU terminal unit real time collect voltage signal, which be managed by SCM what can also send data to administer system. In addition, we can use key-press and LCM to setting RTU parameters.In order to make the data collection be easier, we have developed one monitoring system based on the GPRS remote data transmission network, the system includes lots of RTU terminal unites, what can also save and display and Statistic and analyse data which received from RTU.This paper research results have laid the good foundation for the innovation and the development of the real time monitor for our country low voltage distribution network.
