With the establishment of the “carbon peaking and carbon neutrality”goals

the new energy developes rapidly.The installed capacity of wind power increases sharply

which leads to various types of fan equipment accidents frequently.An increasing trend of fan overspeed has the most serious impact.The testing methods for the overspeed protection of wind turbines have problems such as inconvenient operation

low accuracy

and lack of standardization

which cannot meet the needs of efficient daily maintenance.According to the problems of frequent false alarms and incomplete detection in existing overspeed protection systems

it proposes a set of testing methods for overspeed protection.It covers theoretical analysis

simulation and field test

which is an important means to improve the efficiency of wind energy utilization and reduce the risk of accidents

and ensure the effectiveness and reliability of the overspeed protection strategy under various working conditions.
