TrinaTracker, a leading provider of intelligent solar tracker solutions, recently undertook a comprehensive modernization project at an aging photovoltaic plant in Shandong Province. This plant, one of China’s earliest ground-mounted projects, was facing mounting challenges in efficiency and maintenance due to outdated technologies.
Control System Upgrade
TrinaTracker began by replacing the old electronic control system with its own Terminal Control Units (TCUs) and Network Control Units (NCUs). This upgrade aimed to resolve communication issues and bolster the plant’s defense mechanisms.
Additionally, TrinaTracker incorporated an automated stow strategy that activates during adverse weather conditions. This feature adjusts the tracker based on real-time weather data to minimize risks.
The TCU also detects motor overloads and initiates the stow program, preventing structural damage.
Energy Production Optimization
To optimize energy production, TrinaTracker deployed its SuperTrack algorithms, including the Smart Backtracking Algorithm (SBA) and Smart Tracking Algorithm (STA).
The SBA utilizes patented technology to construct a 3D map of the terrain, enabling real-time detection of optimal parameters.
Meanwhile, the STA relies on a bifacial irradiance model to determine the optimal tracking angle under various weather conditions. This helps reduce unnecessary movement and extend the plant’s operating hours.
Enhanced Operation and Maintenance Practices
The integration of the Trina Smart Cloud platform modernized the plant’s operation and maintenance practices. This solution offers features such as real-time monitoring, rapid fault detection, data sharing, digital maps, and equipment status verification.
The company responsible for the plant’s operation and maintenance praised TrinaTracker’s holistic approach. The integration of digital monitoring and intelligent tracking technologies resolved operational issues and ensured stable long-term operations.
Global Reach and Customer-Centric Approach
TrinaTracker’s intelligent control system is deployed globally, with contracts totaling over 6.2 GW across 16 countries and regions. The company is committed to a customer-centric approach, continuously improving its systems through real-world projects and collaborations. The goal is to reduce costs and increase the efficiency of photovoltaic plants.
Conclusion
This modernization project exemplifies how the integration of intelligent technologies can optimize performance and extend the lifespan of aging photovoltaic plants. By adopting advanced control, tracking, and management solutions, operators can maximize energy production and ensure the sustainability of their facilities.
