Border humidity, and the environment temperature and ambient humidity numerical value are sent to control cabinet 40；When environment temperature and environmental wet degree
Value be more than setting value, and control cabinet 40 receive master controller sending wind power mismatch signal when, start electric-heating assembly 20
Carry out deicing.The temperature and humidity of environment is combined with the wind power mismatch signal that master controller issues, comprehensive descision wind-powered electricity generation leaf
Whether piece 100 freezes, and the accuracy of deicing system starting can be improved, avoid mistakenly opening in the case where blade does not freeze
Open deicing system.Because not necessarily freezing on blade when the temperature and humidity of environment reaches setting value, equally, master controller issues wind
Caused by power mismatch signal is also not necessarily blade icing, it may be possible to other failures；And two factors are combined
Then it is greatly improved the accuracy of deicing system unlatching.
