In the operation of wind power generation systems, when the wind speed changes, the wind turbine relies on the power grid for pitch control to achieve optimal blade speed. When the power grid experiences a power outage, the blades need to be immediately switched to the stop shaft to avoid accidents such as flying cars and falling towers. If the blade shaft still rotates, it will cause damage to the fan.

Previously, lead-acid batteries were used as backup power sources for pitch control. Due to the inherent defects of lead-acid batteries, they have become a major obstacle to the reliability of wind power emergency pitch systems. Under the harsh conditions of "zero tolerance" for UPS power failure, supercapacitors are a new choice for wind power pitching

Precautions for use

1. Supercapacitors should be used within the rated voltage and specified operating temperature range, should not exceed 65 ℃, and should be kept away from heat sources exceeding the operating temperature range;

2. Before using the supercapacitor, it is necessary to confirm the positive/negative electrode and prohibit reverse charging. If the positive and negative poles are connected in reverse, it will reduce the charging and discharging performance of the supercapacitor, and lead to heating, leakage, and rapid decline in service life.

3. Before use, clean the positive/negative terminals of the supercapacitor with a dry cloth to avoid excessive contact resistance and reduce the performance of the supercapacitor.

4. It is prohibited to throw supercapacitors into fire or conduct high-voltage heating.

5. It is prohibited to directly contact the supercapacitor with water, oil, acid or alkali.

6. It is prohibited to squeeze, nail, or disassemble supercapacitors.

7. It is prohibited to short-circuit the positive/negative terminals of supercapacitors with voltages above 0.5V;

8. If any odor, discoloration, deformation or other abnormalities are found in the supercapacitor during use or storage, it should be stopped from use.

9. The electrolyte used in supercapacitors is highly volatile, please do not disassemble the supercapacitors at will.

10. Supercapacitors cannot be discarded randomly, please dispose of them according to national environmental standards
