Abstract

The present paper deals on a concentrating solar system with thermal energy storage, recognized as a potentially useful technology to be integrated in power systems and industries, to support their decarbonization. The paper focuses on the control system of the solar field, employing two-axis (pitch-roll) tracking mirrors (heliostats) and a beam-down system. The paper presents two innovative aspects of the technology: an integral error correction algorithm to enhance pointing accuracy, and the use of an inclinometer for each heliostat, to increase system reliability. The system has been designed, implemented, and tested for more than 12,000 h on an industrial scale, then optimized on-site to maximize charging efficiency, obtaining encouraging results in terms of reliability and aiming accuracy, despite the use of rugged commercial components to keep costs low. The results of the experimental tests show a significant reduction of the aiming error, obtained through the proposed correction algorithm.

基于流化床的聚光太阳能电站及改进型定日镜标定系统控制算法与硬件

本文讨论了一种具有热能储存的聚光太阳能系统，该系统被认为是一种潜在的有用技术，可以集成到电力系统和工业中，以支持其脱碳。本文重点研究了太阳场的控制系统，采用两轴（俯仰滚转）跟踪镜（定日镜）和束下系统。本文介绍了该技术的两个创新方面：提高指向精度的积分误差校正算法，以及为每个定日镜使用倾斜仪，以提高系统可靠性。该系统已经在工业规模上进行了超过12000小时的设计、实施和测试，然后在现场进行了优化，以最大限度地提高充电效率，在可靠性和瞄准精度方面取得了令人鼓舞的结果，尽管使用了坚固的商用组件来保持低成本。实验结果表明，该校正算法显著降低了瞄准误差。

期刊介绍： The International Journal of Energy Research (IJER) is dedicated to providing a multidisciplinary, unique platform for researchers, scientists, engineers, technology developers, planners, and policy makers to present their research results and findings in a compelling manner on novel energy systems and applications. IJER covers the entire spectrum of energy from production to conversion, conservation, management, systems, technologies, etc. We encourage papers submissions aiming at better efficiency, cost improvements, more effective resource use, improved design and analysis, reduced environmental impact, and hence leading to better sustainability. IJER is concerned with the development and exploitation of both advanced traditional and new energy sources, systems, technologies and applications. Interdisciplinary subjects in the area of novel energy systems and applications are also encouraged. High-quality research papers are solicited in, but are not limited to, the following areas with innovative and novel contents: -Biofuels and alternatives -Carbon capturing and storage technologies -Clean coal technologies -Energy conversion, conservation and management -Energy storage -Energy systems -Hybrid/combined/integrated energy systems for multi-generation -Hydrogen energy and fuel cells -Hydrogen production technologies -Micro- and nano-energy systems and technologies -Nuclear energy -Renewable energies (e.g. geothermal, solar, wind, hydro, tidal, wave, biomass) -Smart energy system
