Control systems design and optimisation Laborelec offers decades of expertise in designing, tuning, optimising and commissioning control structures for the power generation industry:  1. Process control for conventional and combined-cycle plants  Boiler control (e.g., drum level control; steam temperature control; air flow rate control and combustion optimisation; global process optimisation). Steam turbine control (e.g., control structure design; controller validation using our tool ARTIST for simulation of grid incidents; by-pass flow and temperature control). Balance of plant, auxiliaries, etc. (e.g., feed water reservoir and condenser level control; feed water circuit flow rate and ΔP control; fuel/gas pressure control; control structures related to cooling towers and aero-condensers). Coordination & operation (e.g., load and pressure control; plant flexibility tests; design of optimal control structure for participation in primary and/or secondary grid frequency control; follow-up of plant participation in grid frequency control and analysis of plant behaviour during grid incidents; root-cause analysis of operational incidents). Adaptation of old analogue control structures to new digital systems. « Hardware in the loop » : validation, debugging and tuning of existing control structures by inserting a simulator in the loop. 2. Process control for nuclear power plants Primary mean temperature (rods) control. Pressuriser control (level and pressure control). Steam-dump control (temperature and pressure modes; control structure design taking the stretch-out into account). Steam-dump to the atmosphere control (pressure control). Water post control (feed water circuit flow rate and ΔP control; condenser level control; small and large bands steam generator level control). Steam turbine control (control structure design; validation using our tool ARTIST for simulation of grid incidents; design of optimal control structure for participation in primary and/or secondary grid frequency control). Analysis and optimisation (control structures and improvement of strategies) of the plant behaviour during large transients like grid incidents (short-circuits near the plant, frequency drops/peaks,…), load rejections from full and intermediate loads, loss of pumps (extraction, main feed-water…), emergency stops (ΔΦ compensation…), turbine run-back (optimisation in function of different parameters), sensor failures (degraded mode…). Validation of controller/protection chains by means of real-time PWR simulators. 3. Process control of dams/basin Level control of (serial) dams (Shem) Load/speed control (Coo) 4. Process control of biogas plants Load control of gas motors Level control of bio-membranes Complete process supervision 5. Process control of steam grids Dynamical steam grid simulation for control structure design and validation Coordination between plant and steam clients Thermal and water balance from DCS data (leakage detection, etc.)
