On January 8, 2025, Anhui Jinli Electric Tech. Co., Ltd. held a technical exchange at Guodian Changjiang Ecological New Energy, mainly involving internal and external lightning protection design, lightning protection detection, the application of intelligent lightning protection in new energy systems, and photovoltaic intelligent power-saving cabinets to reduce costs and increase efficiency of photovoltaic power stations.

  Jinli Electric technicians shared the standards and basis for internal and external lightning protection design in new energy (wind power and photovoltaic) systems. For wind power and photovoltaic systems, national and international standards are usually referenced, such as China's national standards "Technical Specifications for Wind Turbine Engineering" (GB/T 50030) and "Specifications for Construction and Acceptance of Photovoltaic Power Generation System Engineering" (GB/T 19939), as well as standards issued by the International Electrotechnical Commission (IEC), such as the IEC 61400 series and IEC 62548.

  The lightning protection detection mainly includes the detection and evaluation of lightning protection measures in the new energy system. Common contents include grounding system testing of buildings or equipment, lightning strike risk assessment, and effectiveness testing of lightning protection equipment. The detection methods mainly include on-site investigation, use of testing instruments, and data analysis.

  The application of intelligent lightning protection in new energy systems helps realize unmanned substations. Intelligent lightning protection refers to the use of advanced sensors, data analysis and control technologies to achieve intelligent monitoring, early warning and response in lightning protection systems. In new energy systems, intelligent lightning protection technology can monitor lightning activities in real time, predict lightning risks, and automatically execute lightning protection strategies through intelligent control systems to improve lightning protection effects and reliability. At the same time, intelligent lightning protection technology can also be applied to unmanned operation and maintenance of substations to achieve remote monitoring and management of lightning protection systems.

  Jinli Electric recommended a new photovoltaic smart energy-saving cabinet and introduced its cost-reduction and efficiency-increasing effect on photovoltaic power stations. Photovoltaic smart energy-saving cabinet is an energy-saving device used in photovoltaic power stations. It optimizes the operation of photovoltaic power generation systems by precisely controlling the current, voltage and power in photovoltaic power generation systems. Photovoltaic smart energy-saving cabinets can automatically adjust the power generation of photovoltaic power stations according to lighting conditions and grid demand, thereby improving the power generation efficiency of photovoltaic systems and the reliability of grid access. At the same time, photovoltaic smart energy-saving cabinets can also reduce costs and increase efficiency by saving electricity and reducing the operation and maintenance costs of photovoltaic power stations.
