首先, 根據(jù)當?shù)貧庀笈_發(fā)布的天氣預警信息,提前做好光伏電站巡檢工作。對光伏電站的安裝和設備運行情況進行全面細致的檢查,包括檢查螺絲緊固件、扣件是否緊固牢靠,檢查光伏電站的中壓塊、邊壓塊的是否存在松動,及時進行緊固。對于以掛鉤和夾具進行安裝的光伏電站,則應檢查對應設備是否牢固。此外,還需要檢查各個電氣設備的絕緣密封性,如果光伏電站所處地勢較低,應及時將并網(wǎng)逆變器拆離現(xiàn)場或重新選擇高地放置。
其次, 加強光伏電站防風預備工作。 若光伏電站在平屋頂上進行安裝,可采用鐵絲將處于迎風面的串列組件進行捆綁固定;固定墩較小的電站,可以用沙袋等增加電站配重。對沒有加裝防護支架的光伏電站,加裝并緊固防風拉桿,以防光伏支架隨風扭動;地面電站應對陣列兩側(cè)的地錨進行夯實處理。
當暴雨天氣來臨時,多有伴隨雷暴或大風,部分地區(qū)排水系統(tǒng)無法處理的話還可能會出現(xiàn)洪澇災害。對于戶用光伏電站來說,屋頂?shù)呐潘芰^強,一般不會出現(xiàn)涉水的情況,需要警惕的是固定組件的位置被上升水位浸泡引發(fā)故障。 在 水位上升之前及時切斷家中并網(wǎng)開關,最大程度的保障設備安全。
暴雨過后檢查光伏電站時應注意: 首先查看電箱,需要特別關注下浪涌保護器有沒有問題;然后檢查光伏面板是否被損壞,及時清理光伏面板上的雜物,若發(fā)現(xiàn)隱裂組件,應及早進行更換處理。避免徒手碰觸插座、開關、配電箱等帶電設備,以免增加觸電危險。涉水后的設備可能存在電路短路的情況,應盡早聯(lián)系專業(yè)運維人員進行檢查處理,同時可通過保險理賠盡可能挽回損失。
多張?zhí)柲茈姵匕逡赃B接的狀態(tài)被風刮走或者被水沖走時,如果是通電狀態(tài),可能會在日照下發(fā)電而產(chǎn)生高電壓和電流。 需要在其周邊拉起防護繩索等,避免無關人員不小心進入。
此外,暴雨天氣還有可能引發(fā)廣光伏電站周邊土壤含水量飽和,加上缺乏植被保護,容易出現(xiàn)大面積塌方險情,嚴重危及電站安全。若出現(xiàn)塌方情況,首先應及時搶險挽救生命 ,對塌方地段還需采取應急處理措施,鋪設彩虹塑料布并緊急關閉電站內(nèi)的電閘,以保護電站設備。至于光伏電站的后續(xù)處理或損毀嚴重需要報廢的,應和運維人員聯(lián)系后進行操作。
隨著雨季來臨,降雨將更加頻繁、強度更強,部分地區(qū)還將面對臺風等極端天氣侵襲。在惡劣天氣下,一定要做好光伏電站的防護工作,并及時處理受損設備,以免造成更嚴重的財產(chǎn)損失,影響人身安全。
Firstly, based on the weather warning information released by the local meteorological station, carry out inspections of photovoltaic power plants in advance. Conduct a comprehensive and detailed inspection of the installation and equipment operation
of the photovoltaic power station, including checking whether the screws and fasteners are securely fastened, checking whether the medium voltage blocks and edge pressure blocks of the photovoltaic power station are loose, and promptly tightening them.
For photovoltaic power plants installed with hooks and fixtures, the corresponding equipment should be checked for firmness. In addition, it is also necessary to check the insulation and sealing of various electrical equipment. If the photovoltaic power
station is located in a low terrain, the grid connected inverter should be promptly removed from the site or re selected for high ground placement.
Secondly, strengthen the wind prevention preparation work for photovoltaic power
plants. If the photovoltaic power station is installed on a flat roof, iron wires can be used to bind and fix the series components on the windward side; For power stations with smaller fixed piers, sandbags can be used to increase the balance weight
of the power station. For photovoltaic power plants that do not have protective brackets installed, install and tighten wind proof pull rods to prevent the photovoltaic brackets from twisting in the wind; The ground power station should compact the ground
anchors on both sides of the array.
