The nerve centre of operations was the central control room which had been refurbished since the early days of Longannet, to bring the benefits of modern computerised control to the daily operations of units 1-3. Unit 4 retained its original control panels.
The room was fitted with supervisory desks for each unit with sufficient operating equipment to allow the main generating plant to come on-stream, to shut-down and for normal operation. Units were equipped with computer-based automatic boiler controls, on-line data processing equipment and alarm systems which served to monitor continuously and rectify deviations from target conditions to achieve the most efficient operation of the plant.
The new boiler supervisory desks were equipped with the fully integrated APACS self-contained control system, developed by Moore Products Co. The APACS systems included APACS ProcessSuite process automation software and the APACS controller. An integral part of this operating system was LOMIS.
Longannet Operational Management Improvement System (LOMIS)
The aim of the LOMIS system was to optimise the performance of Longannet Power Station. This system was installed on Units 1 and 3.
