Remote online power system monitoring system based on multiinformation acquisition technology

This paper presents a novel and practical system that can realize remote online monitoring on the basis of multiinformation acquisition technology in power system. The technology differs from fieldbus, and Ethernet, power line carrier, SMS, GPRS, ADSL and other communication means are applied to realize data transmission between data acquisition modules and data collection center. Even though there are "no new wires" or "few wires" in the system, the center can transmit and receive the data stream of digital meters or other power monitoring systems reliably. All network protocol and functions are accomplished by a single chip protocol stack. The scheme provides a low cost, operable, embedded, integrated and valid network solution. The practice manifests that the system has high reliability and it is fit for data collection in power monitoring systems.
