Remote Monitoring & Control Systems:
In many cases, it involves monitoring & control of an unmanned substation from another substation of higher voltage levels which is manned. Eg Substation A being monitored & controlled from Substation B. Ashida has executed several projects where the distances between the two substations is large & various media of communication like ADSS, PLCC , Fiber Optic etc are required.
These projects involve installation of RTU at the unmanned substation & transmitting the data to manned substation over reliable media where SCADA software is located.
Various equipments like gateway, protocol convertors etc make up a part of these solutions. Ashida has also executed solutions wherein there is already existing SCADA system at the unmanned substation. These projects involve complex mechanisms with hardwares like gateways to integrate with the existing SCADA of any manufacturer & transmission of the data to an upward level of control.
All of the open protocols like IEC 61850, IEC 103, MODBUS, IEC 60870-5-101 , IEC 60870-5-104 are supported in these architectures to support for remote monitoring & control of substations.
