Inspection every six months.
Inspection items:
Check the waterproof, dustproof, sandstorm-proof, and anti-corrosion conditions of the wind turbine;
Inspect the lightning protection system of the wind turbine once a year;< /p>
Check and test whether the system commands and functions are normal;
Check the electric crane;
Conduct overspeed experiments, flying experiments, normal shutdown experiments, and safe shutdowns as needed , Accident shutdown test;
Check the environmental sanitation conditions inside and outside the wind turbine unit.
When measuring the economic benefits of wind turbines, the unit cost of energy COE (cost of energy COE), that is, the cost per kilowatt hour, is generally used as the evaluation index. As the name suggests, the unit's kWh cost is the ratio of the total cost of the unit to the power generated.
For example, for example, the cost of a 2MW wind turbine (parts, construction, maintenance, etc.): X yuan
In the design life of the wind turbine of 20 years, the total The power generation capacity is: Y kilowatt hours.
The cost of electricity is X/Y
