service process
what are the problems in data review?
according to the previous technical due diligence of the power station, the majority of problems occurred in the data review. because the design, construction and construction of wind power are relatively complex, there are a large number of data and technical problems in each link, so the data review of the power station tests the comprehensive quality of engineers.
what are the common problems in fan inspection?
in the process of technical due diligence, fan inspection is the most important. the operation of the whole fan includes multiple systems, and each system should be comprehensively inspected with strong professionalism. in the large-scale technical due diligence, it is more necessary to conduct a comprehensive inspection of the wind farm by discipline and system.
what are the common aspects of electrical problems in wind farms?
the electrical system of the wind power station is complex, including wind turbine generator units, box type transformers, power collection lines, main transformers and supporting control equipment, power transmission lines, reactive compensation equipment, etc. the daily maintenance of electrical equipment should have operation inspection records, pay attention to the frequent electrical failures, form corresponding written materials, and evaluate the electrical equipment.
what are the problems of power generation?
each wind power station has its own characteristics of power generation. common power generation problems are often inconsistent with theoretical power generation. in this case, the power station should be considered in all aspects, including wind abandonment rate, equipment failure, etc. the quality of wind resources is an important factor that seriously affects the power generation.
