as a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. under the background of carbon peaking and carbon neutralization, the development prospect of china's wind power industry is very broad. it will maintain rapid development for a long time in the future, and its profitability will be steadily improved with the gradual maturity of technology. china is rich in wind resources, especially in the northwest, northeast and coastal areas. it is of long-term significance to vigorously develop wind power for the adjustment of china's power structure. at present, china has a large number of installed wind power with many types and quantities. how to ensure the normal and stable operation of power plants and ensure the power generation has become the focus of attention of major enterprises.
as an inspection, testing and certification group established for many years, noa has provided professional fan inspection and testing services for many owner companies, power plant purchasers, investors, insurers, etc., and has won the recognition and trust of customers. in the current rapid development of the wind power industry, noa adheres to high standards of technical requirements and high standards of technical services. by dispatching professional engineers, it can conduct comprehensive inspection, testing and acceptance of the whole wind farm. the company has professional technicians in many fields, who can analyze, evaluate and identify the technical problems, asset problems, design problems and document consistency problems of the whole wind power station, to provide professional third-party services for our customers. as a professional, authoritative and comprehensive third-party inspection, testing and certification agency, noa has provided inspection and testing services to more than 1gw wind airports, and has accumulated valuable practical experience in the wind power market. in the future, we will uphold noa's high standards and requirements, according to the national standards and industry requirements, and provide higher service levels to enterprises, so as to protect wind power enterprises.
noa provides wind power technology due diligence services, including:
one. review of project compliance file
two. assessment of wind resources and power generation
three. adaptability assessment of unit at specific site
four. feasibility study and planning report
preparation of project proposal, pre feasibility study report, wind farm project development application report, wind farm project approval report and other planning reports
five. other evaluation contents
fire protection design assessment, civil design assessment, electrical and access system assessment, wind turbine safety assessment, wind turbine operation reliability assessment, wind turbine availability assessment, wind turbine power curve detection, assessment, power generation loss analysis, temperature and vibration data analysis, operation and maintenance capability assessment, risk recommendations and measures.
six. inspection of operation state of fan unit components
the operation status inspection of wind turbine components can be carried out by comprehensively inspecting and testing all components of the wind turbine, using different inspection methods and analysis systems to evaluate the equipment performance and operation status of the wind turbine, and find possible early defects. the in service inspection of fans can minimize the downtime, extend the service life of fans, and maximize the benefits of the wind farm. the key components of the fan are covered in the inspection scope: drive chain system, hydraulic system, pitch yaw system, electrical system control protection system, blades, etc.
seven. other due diligence contents
oil analysis, transmission chain vibration test, gearbox endoscope inspection, electric control system function test, fan blade and internal inspection, tower verticality inspection, tower nondestructive testing, and bolt nondestructive testing.
