摘要
In a state monitoring system for a wind turbine generator, a first buffer 44 repeats overwrite of data regarding a lightning strike parameter and accumulate the data temporarily. A first trigger signal output part 46 outputs a first trigger signal when the lightning strike parameter exceeds a threshold. A memory part 48 acquires and accumulates at least a part of the data regarding the lightning strike parameter of a period from the first buffer 44, the period including before and after an output time of the first trigger signal. A reference value estimation part 50 estimates a reference value of the lightning strike parameter based on a first data corresponding to a first period before the output time of the first trigger signal among the data stored in the memory part 48. A damage state estimation part 52 estimates a damage state of the blade 21 based on a second data of after the output time of the first trigger by considering the reference value.
