摘要

In the power network monitoring system, the voltage signal and the current signal sampled can be transmitted to the cloud server through the public network as long as a voltage sampling apparatus and a current sampling apparatus are installed in the main switch board of power distribution network. The cloud server ascertained the state of device in the power distribution network, such as when to switch on and off the device and how about the energy consumption, by conducting mathematical contrast between the relevant signal characteristic quantities extracted via mathematical calculation and analysis and the relevant characteristic quantities of the operating device in the power distribution network. The operating state data of related device can be transmitted to the device manager or user through the public network. With extremely low investment on the whole system and extremely simple engineering installation, it has a broad application prospect. The experiment proves the validity of power network monitoring system technology.
