The latest fibre comms technology to be used within BSP Grid and Primary substation design means the current MICROSOL Remote Terminal Unit (RTU) needs to be deployed using a distributed I/O approach. This requires development of remote cell technology. A cell would be installed in each protection cabinet, communicating via a fibre ring back to the main and standby comms cabinet. The cell would interface to the Substation plant locally within each protection bay via klippon links eliminating the need to hardwire back to the MICROSOL cabinet via a marshalling cabinet. This would initially be as stand-alone but with the capability to integrate directly to the RTU subject to the interface protocol being agreed.
In order to rationalise substation design the use of distributed fibre optic communications is to be proven via trialling. Key aims:

  • Bench test the new RTU equipment (standalone)

  • Test with existing 132kV substation control system

  • Test with fibre communications

  • Extended trial to include distributed RTUs.
