Nantengba Prefecture Pumped Storage Project Supporting Bohu County 600,000 kilowatt photovoltaic project EPC General Contract
Nantengba Prefecture Pumped Storage Project Supporting Bohu County 600,000 kilowatt photovoltaic project site is located in the southern part of Bostenhu Lake, Bayinguoleng Mongolian Autonomous Prefecture, about 26km from Bostenhu Lake, about 24km from Bostenhu Township, and east to Zhuyin Huduke Village. The site scope is located at 87°02′0.05″～87°07′19.39″ in Dongdao, 41°39′42.43″ to 41°43′40.13″ in north, and the altitude is between 1150m and 1Sugar daddy250m. The land attribute of this project is other grasslands, and the terrain is importantly an alpine slope. The planned traffic capacity of the site is 600MW, and the DC side-mounted installation capacity is 761.28MWp. The photovoltaic area is divided into three parts: 1#, 2# and 3#. Among them, the 1# area occupied about 2676.27 yuan, and the 2# area occupied about 102 yuan. 35.18, the 3# block takes up about 4634.74, and the total occupancy is about 17546.19. There are existing passes on the north side of the site. The routes can be led by the existing passes. Is the internal road conditions of the site more convenient? The project has a new 220kV lift station, and the project has a installation and installation capacity of 105MW/210MWh. The project land does not occupy basic farmland, and the terrain is flat and open, which can meet the requirements of photovoltaic power generation, and is suitable for the overall planning of local land application, and is suitable for national industry policies and land supply policies. It was initially judged that there were no cultural relics and ancient artifacts on the site, and there were no airports around it, which did not affect military facilities and did not cover mine resources.
Construct 182 single crystal silicon squares, and apply N-type 610Wp TOPCon single crystal double-sided double-glass components, the number of components is 1248,000 blocks, including 1# block 178,464 blocks, 26 single crystal silicon squares; 2# block 728,000 blocks, 106 single crystal silicon squares; 3# block 341,536 blocks, 50Single crystal silicon square. The photovoltaic Escort is connected in series into the series inverter. After the box is increased to 35kV, it is sent to the GCC lift station via a 35kV electric wire.
2.1.2 Tender scope and bidding section (package) plan: This project plan is divided into two bidding sections, among which 2# subdivisions are 350,000 kilowatt photovoltaicsSugar daddyThe EPC project in the field is the first section, and the EPC project in the 250,000 kilowatt photovoltaic field in the two areas of #1 and #3 is the second section. The bidding tasks include but are not limited to: detailed project survey, preliminary design, technical specifications, construction drawing design, equipment data procurement and supply, construction installation project construction, project management and coordination, construction temporary construction The workplace management, equipment adjustment, regular testing, network-related experiment, system connection, joint trial operation, technical training, experience collection (including special experience collection, stage experience collection, completion experience collection), etc. The tasks of each section are as follows:
(1) EPC project of the first section of the 350,000 kilowatt photovoltaic area
National-Ba Prefecture Pumping StorageSugar babyThe capacity of the first section of the 600,000 photovoltaic project in Bohu County is 350MW, the DC side-mounted installation capacity is 444.08MWp, the number of components is 728,000, and 106 single crystal silicon square meters are built. The task content includes but is not limited to Sugar daddy: The exploration (geographical detailed survey) design of photovoltaic field, the procurement and supply of all equipment (except photovoltaic components and inverters) data, the site is level, photovoltaic components, inverters, brackets, box changes and other equipment, as well as foundation, DC cables, electric collectors (all power cables from inverters to box changes, box changes to lift stations), in-site routes, ranges, The construction of lightning protection grounding, fire protection and other projects, secondary transportation, testing, testing, testing, and inspection of construction, soil and water maintenance and environmental protection projects, as well as inspection and acceptance of defect removal, functional test, and functional guarantee of the entire system of the above projects, joint trial operation, technical and after-sales service, passenger training, and standard investment, etc.
① Design task scope
Detailed survey, preliminary design of all projects in this section (responsible for the reporting and reporting of the second section of the Sugar baby to report the results after the second section), technical specifications, construction drawing design, test drawing, completion drawing editing, etc. Exploration design scope includes but is not limited to: photovoltaic fieldThe main engineering exploration and design also includes environmental protection, water protection, fire protection, quality inspection, repair, safety evaluation, professional health, lightning protection and grounding, etc., which are related to the relevant special designs that meet engineering experience requirements, as well as the exploration design of construction auxiliary facilities such as construction water and electricity. No conditions must be jointly recruited to complete the project to meet the bidding investment request.
The depth of document compilation of each design stage should meet the requirements of the current standards, regulations, standards and relevant regulations of the country and industry, and meet the requirements of the “National Dynamic Group New Dynamic Intelligent Station Construction Regulations”. Responsible for this episode is one of the most serious characters. Although her appearance and overall design coordination and service (including live services), she jointly conducts the review of all design documents and drawings and various reviews, acceptance, preparation, and document documents, and is responsible for design briefing and design review tasks.
