Solar photovoltaic (pv) application for conveying clean energy Zhang Bei - male Ann new city The male 1 million v high voltage engineering (Ann Hebei north

Solar photovoltaic (pv) net news: on July 21, as in yu county 3 r003 - zhangjiakou Wire drawing is in place, the last phase 3 r012 section by its power connecting the north Zhang Bei - ji The male 1 million v high voltage ac transmission line engineering (Ann Hebei north) Smooth realization all kilovolt high voltage transmission line project is completed, each year to more than 7 billion KWH for male Ann district transportation of clean energy, to achieve 100% male Ann new clean energy supply, build green interweave, clean and bright blue ecological wisdom male Ann, solar equipment, provide important support services for one thousand construction task.

in north region is the focus of the renewable energy in hebei province and even the whole country sends out the area, solar power grid, wind energy, solar energy resources are rich. Renewable energy installed size of 2020 is expected to more than 20 million kw, but local given ability is insufficient, need given massive sent. Zhang Bei - Male, 1 million kv high voltage transmission line project is to improve the zhangjiakou region service delivery capacity of renewable energy, and male Ann district green power key projects, ji learned all laid the foundation for engineering comprehensive was put into operation.

Zhang Bei - The male 1 million v high voltage ac transmission line engineering (Ann Hebei north) From Zhang Bei 1000 kv substation, check in zhangjiakou r036 3, no. 3 l036 tower in yu county. Line via zhangbei county, zhangjiakou district, huaian, YangYuan county, yu county, total length of 2 & times; 218 kilometers, accounting for whole kilometers with double towers erect, the remaining 2 & times; 86 km by two single loop parallel erection, China solar power network, a new tower 558, the highest tower 173 meters high, all most single-base tower material of 526 tons. Uhv power grid ring formation in the north China region is an important part of this network and state grid corporation & other; New infrastructure & throughout; The key power grid project, relying on long distance, large capacity of uhv ac transmission technology will zhangjiakou region rich clean electricity to male the new load center, avoid aggravating Beijing 500 kv ring & other; North to south throughout the &; Trend through.

whole %, on-site transportation difficulties, high construction difficulty, combined with the zhangjiakou region winter long summer short, solar portal, winter cold and wind cause local effective period is less than 6 months, height of nearly 3000 the number of present construction at the same time. Lines in the process of building successful cross is located in the taihang mountains of yu county, zhangjiakou cannot be set on the terrain stay outside environment, the successful completion of the distance of 780 meters, 500 meters elevation difference, the two base DaWei construction tasks below. Engineering cross multiple 500 kv lines, railway, high-speed railway, highway, riskier bases, such as the Great Wall ruins, among them, the engineering bid 2 in 3. 2 km pay-off section, at the same time, across tang call railway, 500 kv line rice dish button across the frame height to break its ji north power across the frame height history.

in order to ensure the project to return to work on schedule during the outbreak, its Chinese hebei north power actively implement the superior decision deployment, the early stage of the organization the contractors strictly implement the territorial government epidemic prevention and control requirements, the careful formulation field work to return to work plan, the epidemic prevention and control plan the site emergency disposal plan, screening of 55 first return to work in personnel play began on February 16 isolated life of 14 days. Set up a working group on epidemic prevention and control engineering site, prepare protective supplies, set the isolation room, strict implementation of closed-end management, temperature monitoring, protection measures 'including disinfection, separate dining regularly, solid fine all epidemic prevention requirements, China solar energy network, make preparations for emergency treatment of sudden outbreak, strengthen and local administrative department of health and anti-epidemic departments and professional communication and coordination of medical institutions, implement epidemic information sharing. Next, its Chinese hebei north power will uphold the epidemic prevention and control and safe production & other; To combine and balance & throughout; Principle, organizing various contractors and efficient to carry out the follow-up work, for getting rid of the completion acceptance and ensure engineering & other; Zero defect & throughout; Transfer, safety, high quality and efficient in operation.

this paper statistics the September to today issued a total of 2. 85 gw pv power plant EPC and 1. 9 gw component bid opening information. Among them, the EPC project owner units is given priority to with soe/state, this also reflected from the side, in project bidding and parity, the state-owned enterprises have become the absolute main force. Specifically, CGNPC in development of 410 mw, 603 mw, guangzhou energy saving 220 mw, 345 mw, jin can group the people vote for 200 mw, 190 mw hubei energy group, huaneng power 180 mw
