F2103 GPRS IP Modem applied in smart grid

Visibility: Open to anyone

F2103 GPRS IP MODEM is a kind of cellular terminal device that provides data transfer function by public GPRS network.


It adopts high-powered industrial 16/32 bits CPU and embedded real time operating system. It supports RS232 and RS485 (or RS422) port that can conveniently and transparently connect one device to a cellular network, allowing you to connect to your existing serial devices with only basic configuration. It has been widely used on M2M fields, such as intelligent transportation, smart grid, industrial automation, telemetry, finance, POS, water supply, environment protection, post, weather, and so on..

Application in smart grid


In the power system, consume large amounts of reactive power devices exist, the use of power system voltage of these devices will generate intense volatility, such as the impact of reactive power load: rolling mill, electric arc furnace, electric railway and so on. At the same time there are users of the system voltage stability has higher precision equipment requirements: such as computers, medical equipment and so on. If the reactive power can not be controlled, it will cause adverse effects on the grid voltage. Also lack of reactive power reserves will lead to lower voltage levels. For these reasons, how quickly and effectively solve the power system reactive shortfall has important practical significance. After the installation of reactive power compensation controller in the grid can provide inductive reactance reactive power consumed by reducing the grid to provide power to the inductive load, reactive power delivered by the line, due to the reduction of reactive power flow in the grid, thus reducing transportation lines and transformer reactive power caused by power loss, which is the reactive power compensation. Reactive power compensation can improve the power factor is less investment and quick results in a loss reduction of energy saving measures.


With the development of industrial automation, the original site with a notebook computer or data logger and reactive power compensation controller wired communications and data collection has grown to a remote intelligent monitoring, many must unattended equipment or monitoring point, not suitable to build a wired communication network, with Four-Faith IP Modem, through existing wireless network intelligence gathering from remote data needed to put together, greatly improving efficiency.
