PV Power Station O&M from Lightning Protection-Technical Sharing by Hunan Oumaan Technology Group in Chizhou,Anhui Province,China
On 25th September 2024,the 2024 Annual Meeting of PV Power Station Intelligent Operation and Maintenance Technology and the 2023 Fault-free PV Power Station Management Achievement Conference,hosted by the Operation and Maintenance Branch of China Electric Power Technology Market Association,was held in Chizhou,Anhui Province.Faultless PV power station creation of PV power station stock assets to improve the quality and efficiency of great significance,the Association to carry out faultless PV power station management results assessment after three years,2023 rated 626 faultless PV power station management results,the results are remarkable.
Hunan Oumaan Technology Group Co.,Ltd.as the vice president of the Association,the electric power industry lightning protection technology service centre,to attend this meeting,we share the valuable experience in the process of PV power station operation and maintenance from the perspective of lightning protection.
Up to now,China's photovoltaic power plant installed capacity of 712.93 million kilowatts,2023,the results of the management of fault-free photovoltaic power plants accounted for only about one-tenth,a long way to go.PV power stations in the field face complex natural environments,with lightning strikes tripping the collector line towers,high grounding resistance due to the rocky structure of the substation site,and flashover problems due to condensation on the external insulation of the power supply are all troublesome problems for PV power generation.
In response to the above problems,Oumaan Technology Group representative Yang Zhibing launched a detailed analysis at the meeting and introduced four core technologies that can solve these problems.
For direct lightning disasters,HD-PLR can achieve no direct lightning in key areas(such as booster stations),completely eliminating lightning safety hazards.
For accidents such as moisture discharge and insulator creepage caused by condensation,DSAN superhydrophobic and oleophobic coating can make the surface of substrate possess water-and oil-repellent properties,preventing condensation and other factors prone to triggering electric field aberrations such as condensation on the surfaces of metal parts,insulators,and so on.This ensures the stability of operation and maintenance.
For the grounding device,flexible grounding technology can reduce the grounding resistance of the transmission line tower,reduce the grounding resistance of the substation,inhibit the ground voltage rise caused by lightning strikes,and protect the metal grounding electrode from soil corrosion.Flexible grounding technology can also be applied to water-based photovoltaic power stations to solve the problem of water corrosion of metal grounding electrodes,underwater grounding is difficult to complete.
For the problem of monitoring,HD-LDL lightning online monitoring system combines the authoritative big data in the fields of meteorology and power grid with AI intelligent algorithms to achieve early warning and accurate positioning,which greatly saves the cost of manual investigation.
Oumaan Technology Group,for many years,has been committed to the research of lightning protection and grounding technology,and has implemented a large number of lightning protection and grounding renovation projects in new energy power stations all over the country,achieving fruitful results.We have our own team of experts,construction teams and production bases,specialising in solving all kinds of lightning protection related difficulties,including but not limited to:high grounding resistance,lightning strike tripping of power supply equipment,sustained lightning strikes burned equipment,poor environment corrosion is serious,underwater grounding is difficult to complete......
