With the rapid development of renewable energy, photovoltaic power stations have been widely used as a clean energy power generation method. The operation and maintenance management of photovoltaic power stations realizes functions such as operating data monitoring, fault monitoring and diagnosis, and on-site security management and control through the smart photovoltaic operation and maintenance management platform. However, intelligent monitoring in the lightning protection sector is still a blind spot in existing photovoltaic projects. Since photovoltaic power stations are exposed to a large area of the surrounding open outdoor environment, they face a greater risk of lightning strikes. Lightning strikes may not only cause equipment damage and economic losses due to the inability to connect to the grid for power generation but may also threaten the safety of power station operation and maintenance personnel, posing huge challenges to power station operation and maintenance. To cope with these challenges, Anhui Jinli proposed a "photovoltaic power station smart lightning protection system solution". This solution integrates key technologies such as SPD online monitoring, lightning early warning online monitoring, and grounding resistance online monitoring, aiming to provide photovoltaic power stations with comprehensive lightning protection measures and realize intelligent monitoring and management. The smart lightning protection system is a solution that integrates advanced technology and intelligent management methods. It aims to provide comprehensive lightning protection measures for photovoltaic power stations and provide non-periodic operation and maintenance guidance and suggestions to the site. The system monitors and analyzes equipment status, lightning activity, and grounding system conditions in real time through key technologies such as surge protector online monitoring, lightning early warning online monitoring, and grounding resistance online monitoring. Through intelligent algorithms and models, the system can predict the changing trend of lightning risks and the changing trend of the surge protector throughout its life, and send out early warning signals in time to help operators take necessary protective measures. By introducing smart lightning protection systems, photovoltaic power stations can improve their capabilities, reduce lightning strikes, reduce daily maintenance of lightning protection equipment, and ensure the safe operation and sustainable development of power stations. This intelligent lightning protection solution will provide a safer, more stable, and efficient operating environment for photovoltaic power plants.

The types of loads we connect to a building’s electrical system today vary greatly from what may have been connected 50 years ago. Today’s buildings rely heavily on electronics, communications, and microprocessors for some of the most basic functions. These include electronic controls built into a compact fluorescent or LED (light-emitting diode) light bulb, as well as sophisticated building control and automation systems. Automated systems are incorporated into a building’s emergency system as well. This increased use of electronics demands an electrical infrastructure that takes into account the increased sensitivity of electronic loads to voltage transients that can enter the electrical system. These transients can enter through external sources such as lightning and other electrical faults occurring outside the building, as well as through the routine switching of loads inside the building that occur as part of normal operations. Since its establishment in 2006, Jinli Electric has been deeply involved in surge protectors for nearly two decades, adhering to the corporate mission of "creating the world's No. 1 lightning protection brand to protect users from lightning intrusion". The independently developed and produced surge protectors, lightning arresters, backup protectors, etc. are at the forefront of the industry in terms of quality and performance and are very effective in mitigating transient overvoltage. This prevents equipment damage or malfunction due to excessive voltage caused by switching, direct or indirect lightning strikes, or crossing of high-voltage power lines and low-voltage power lines. Better ensure the safety of the building itself and electrical equipment. Transient events are by their nature very short, fast events, typically in the range of 5 to 200 microseconds. Momentary increases in voltage can create permanent conductive paths that can cause damage to electrical components. Today we need to better apply surge protectors to buildings to protect the safety of people and property.

  Due to the greenhouse effect and the El Ni ñ o phenomenon, high summer temperatures are prevalent. Excessive temperature not only leads to a decrease in power generation, but also seriously affects the operation and service life of photovoltaic modules, causing a decrease in the insulation performance of motor coil enameled wires of photovoltaic modules, cables, inverters and other electrical equipment, softening or even melting of cable insulation, resulting in circuit short circuits, causing fires in photovoltaic power stations, endangering personal and property safety. The impact of high temperature on electronic devices such as inverters is manifested as:   1) Photovoltaic power plants have electronic equipment such as inverters, which contain a large number of electronic components, integrated circuits, and high-power switching transistors. The working temperature range of civilian grade electronic components is -35 ℃~70 ℃, and the working temperature of most photovoltaic inverters is -30~60 ℃. Beyond this operating temperature range, both electronic circuits and integrated circuits will enter an unstable state. This state can cause circuit equipment to shut down in mild cases, and in severe cases, it can lead to circuit logic confusion and equipment damage.    2) There will be a large number of electrolytic capacitors in the photovoltaic inverter. In order to stabilize the voltage at the photovoltaic input terminal and prevent interference, there will also be a varying number of large capacity electrolytic capacitors. These capacitors are very afraid of high temperatures, which will gradually evaporate the electrolyte inside the capacitor, leading to a decrease in capacitor capacity and even scrapping.   3)The high-power thyristors in photovoltaic inverters are highly sensitive to high temperatures. Excessive temperatures can affect the correct operation and service life of high-power thyristors, and cause them to burn out.   Anhui Jinli PCB type surge protection deviceis widely used on the AC and DC sides of inverters, and the product fully complies with GB/T 18802.31 Low-voltage surge protective devices-Surge protective devices for specific application including d.c.-Part 31: Requirements and tests for SPDs in photovoltaic applications. Andour PCB type SPDs havepassed TUV certification andhave undergone 1000 hours of aging testing in a dual 85 ° C (temperature 85 ° C and humidity 85% environment) environment, and all aspects of performance testing are normal to ensure the safe operation of photovoltaic inverters on site.
