The invention provides a method and device for monitoring an operation state of a wind turbine generator. The method for monitoring the operation state of the wind turbine generator comprises the steps that current operation data and historical operation data of the to-be-monitored wind turbine generator are acquired; operation state influence parameters of the to-be-monitored wind turbine generator are determined from the historical operation data according to a pre-established operation state influence factor determination model; and the operation state of the to-be-monitored wind turbine generator is determined according to the current operation data corresponding to the operation state influence parameters and a pre-established working condition monitoring model. According to the method and device for monitoring the operation state of the wind turbine generator, power key influence factors of the wind turbine generator are deeply mined; the constructed wind turbine generator operation state model based on
