Drax Power: 11KV Biomass Enabling Works
In conjunction with Vital Power, Ematics provided the 11kV Enabling Works for the Biomass Project at Drax Power Station.A new SCADA / Control system was provided to allow the control and monitoring of the electrical distribution system including refurbished breakers, new 11kV Biomass Switchboards (11kV incomers, bus couplers and feeders), 11kV/415v step down transformers and 415v Biomass Switchboards (415v feeders switchgear and bus couplers). The electrical systems also included a new essential supplies system including all batteries, chargers and UPS equipment.

ABB REF542 Plus Interface
The control system monitored a number of ABB REF542Plus Intelligent Relays in the electrical Switchrooms via a number of means including Hardwired I/O, Dual Modbus RS485, Modbus TCP/IP and Web Ref Software. The link type used was dependent upon the data being monitored, however the serial interfaces provided a means for collecting time and date stamped data.
Hardwired I/O links were used for a number of new and refurbished Breakers which were connected to the Advantys STB remote I/O units.
Dual Modbus RS485 multi-drop communications networks were used between the Hot Standby Quantum PLCs and the ABB REF542Plus Intelligent Relays on the 11kV Switchboards with the communications arranged such that it is possible to read values via both ports simultaneously thus providing communications redundancy in the event of a cable or network failure.
