Day‑to‑day monitoring and long-term optimization
Operators use a combination of sensors, supervisory control systems, and analytics to monitor concentrator plants. Continuous data collection allows quick response to faults and gradual optimization to maximize energy output.
Monitoring and optimization activities:
- Real-time telemetry: position sensors, irradiance meters, flux cameras, and temperature sensors feed data to a control center.
- Performance analytics: software identifies underperforming mirrors, tracking errors, or decreased reflectivity to schedule maintenance.
- Predictive maintenance: patterns in vibration, drive currents, and alignment inform replacement schedules before failures occur.
Optimization strategies:
- Re-aiming heliostats for even receiver flux distribution.
- Scheduling cleaning and inspections based on measured soiling rather than fixed intervals.
- Integrating weather forecasts to optimize charging of thermal storage and dispatch of power.
Proactive monitoring reduces downtime and operating costs while improving overall plant capacity factor and lifetime performance.
