Control systems design and optimisationLaborelec 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 for hydro-electricity plants- Level control of (serial) dams
- Load/speed control
4. Process control of biogas plants5. Process control of steam grids- Coordination between plant and steam clients
- Thermal and water balance from DCS data (leakage detection, etc.)
