Recently, the achievements of an intelligent information management system for photovoltaic power plants, jointly developed by the General Institute of Hydroelectric Water Conservancy Planning and Design, China Power Investment Group's Yellow River Upstream Development Co., Ltd., and Beijing Mulian Energy Software Technology Co., Ltd., were officially announced. This groundbreaking system is set to revolutionize how solar power stations are managed and monitored.
Photovoltaic Power Station Management Is Becoming More Transparent
The system offers real-time online monitoring of photovoltaic power plants and advanced analysis of key performance indicators such as operational efficiency and equipment failure rates. It marks the first integrated platform in China that enables digital and intelligent management of solar power stations. The technology has already been successfully implemented at several major projects, including the 20MWp Phase I project in Qinghai Province, the 50MWp Wulan project, and the 10MWp Sangri project in Tibet.
"This research not only provides smart and efficient data processing for on-site workers but also serves as a critical foundation for enterprises and governments in decision-making and policy formulation," said Wang Minhao, executive deputy director of the General Institute of Hydroelectric Water Conservancy Planning and Design and director of the National Wind Power Information Management Center.
Enhancing Rapid Information Processing in Solar Plants
The intelligent management system includes various components such as production and operation management software, data acquisition tools, coding systems, and performance indicators. According to Xie Xiaoping, general manager of the Upper Yellow River Hydropower Development Co., Ltd., large-scale solar farms face challenges due to diverse equipment, varying standards, and uneven quality. These factors require more maintenance personnel compared to wind or hydro projects, making rapid fault detection and information processing essential.
"The system allows remote monitoring of inverters, fault detection, and color-coded analysis to trace issues quickly. This significantly improves the speed of fault resolution, enhances operational efficiency, and ensures safer, more standardized plant operations," he explained.
Optimizing Plant Management and Operations
Wang Minhao highlighted that the system provides valuable data for evaluating design accuracy, component performance, and inverter efficiency. For example, at the Golmud PV site, the system confirmed that actual generation matched theoretical projections, validating the reliability of the initial design. When discrepancies arise, it allows for revisions to improve future designs and standards.
The system also helps in assessing the performance of different inverter models. At Golmud, the average conversion efficiency of 500kW inverters was found to be 96.41%, meeting design requirements. This level of precision supports better decision-making and operational optimization.
Promoting Healthy Growth in the Solar Industry
With China’s "12th Five-Year Plan" aiming for 21GW of solar capacity by 2015, the industry is growing rapidly. However, many gaps remain in standardization and quality control. The newly launched intelligent system is seen as a crucial tool for improving transparency, promoting competition based on data, and supporting long-term sustainable development.
According to officials from the National Energy Administration, the system will play a key role in data collection, policy formulation, and industry guidance. It also supports the establishment of a nationwide solar resource network, helping to monitor and manage solar energy distribution effectively.
This innovative platform represents a significant step forward in making solar energy more efficient, reliable, and scalable—setting the stage for a smarter and more sustainable energy future.
