A clearance abnormality detection method for a wind turbine generator set. The method comprises: acquiring, from operation data of a generator set within a predetermined period of time, operation data of when an air speed is within a predetermined air speed range and a power is within a predetermined power range, and dividing the operation data into a plurality of operation data fragments; with regard to each operation data fragment, when a first specified clearance value therein is less than a first preset value and the operation data fragment meets a preset condition, determining the operation data fragment to be a clearance-abnormal fragment; and determining a clearance abnormality of the generator set according to the clearance-abnormal fragment. Further comprised are a clearance abnormality detection apparatus for a wind turbine generator set, and a medium, a system and a wind turbine generator set. The method can effectively solve the problem of it being impossible to predict a clearance risk of a wind turbine generator set in advance.

Abstract An energy-harvesting compute grid includes computing assemblies that cooperate with mobile energy harvesters configured to be deployed on a body of water. The plurality of energy harvesters are positioned on and move adjacent to an upper surface of a body of water, and the locations of the energy harvesters can be monitored and controlled. The widespread gathering by the harvesters of environmental data within that geospatial area permits the forecasting of environmental factors, the discovery of advantageous energy-harvesting opportunities, the observation and tracking of hazardous objects and conditions, the efficient distribution of data and/or tasks to and between the harvesters included in the compute grid, the efficient execution of logistical operations to support, upgrade, maintain, and repair the cluster, and the opportunity to execute data-gathering across an area much larger than that afforded by an individual harvester (e.g., radio astronomy, 3 D tracking of and recording of the communication patterns of marine mammals, etc.). The computational tasks can be shared and distributed among a compute grid implemented in part by a collection of individual floating self-propelled energy harvesters thereby providing many benefits related to cost and efficiency that are unavailable to relatively isolated energy harvesters, and likewise unavailable to terrestrial compute grids of the prior art.
