3BHE024577R0101 PPC907BE 3BHE024855R0101 UFC921A101 Programmable logic controller (programmable logic con-troller, PLC) technology has become quite mature after decades of development. With its complete varieties and functions, it has been widely used in various fields of industrial control. Using PLC to realize the RTU function of medium and low voltage distribution network automation can well meet the unique requirements of RTU. In the domestic market, there are PLC products from many famous manufacturers. These products, ranging from simple to complex, are self-contained series that can meet the specific requirements of different applications.

3BHE024577R0101 PPC907BE 3BHE024855R0101 UFC921A101 Most PLC products in the low to medium range include discrete point inputs and outputs (the number of points can be increased or decreased depending on the application), analog sampling inputs, clocks, communications, and other functions. Using the ready-made functions of such PLCs, it is easy to realize the RTU function of the automation of medium and low voltage distribution networks. Use the discrete input point of PLC to realize telecommunication, discrete output point of PLC to realize remote control, analog sampling input of PLC to realize telemetry, communication function of PLC to realize communication with the host.

3BHE024577R0101 PPC907BE 3BHE024855R0101 UFC921A101 accomplish all of these functions, no additional hardware is required, just simple programming of the PLC according to the actual situation of the switch room. Not only that, using the analog output function of PLC, it is even possible to realize the remote regulation of the distribution network. For example, adjusting the ratio of the regulating transformer, adjusting the voltage and current phase angle of the static reactive power compensation equipment, and so on.
