As an advanced solar energy utilization technology, tower-type CSP employs a large-scale heliostat field below to precisely reflect and concentrate sunlight onto the absorber at the top of the heat tower. This process converts solar energy into thermal energy, which then drives the power generation system. Within this process, the precise tracking and control of the heliostats are particularly critical.
Under suboptimal sunlight conditions, a real-time control system capable of precise solar tracking and reflection is essential to achieve efficient conversion from solar energy to electricity. This places extremely high demands on the reliability of the control system.
The Demanding Challenges of High-Altitude Environments
The client's initial control solution utilized fully imported brand components. As CSP projects fully transitioned to market-driven operations, cost reduction and efficiency enhancement became industry consensus. Particularly for projects located on the Tibetan Plateau at 5,500 meters above sea level, even more stringent demands were placed on component reliability and stability.
High-altitude environments feature low atmospheric pressure, intense ultraviolet radiation, and significant diurnal temperature variations, posing severe tests for electrical equipment's insulation performance, heat dissipation capabilities, and material weather resistance.
