Abstract

The invention discloses a fan fault inversion method and system based on 3D simulation and panoramic time series data sampling, and the method comprises the following steps: obtaining the measurementdata of a fan, and storing the measurement data of the fan in a time series database at the same time interval according to the time sequence; obtaining inversion starting and ending time of historical fault events of the fan; querying all measurement data of the fan in the inversion starting and ending time periods from a time sequence database, and generating a section data stream with continuous time; and driving the fan 3D model to perform simulation by taking the section data flow with continuous time as a data source so as to display the whole running state process before and after the historical fault of the fan occurs.

Description

technical field [0001] The invention specifically relates to a fan fault inversion method based on 3D simulation and panoramic time-series data sampling, and belongs to the technical field of wind power generation. Background technique [0002] A wind turbine (hereinafter referred to as a fan) is a power generation device that converts the kinetic energy of the wind into mechanical energy, and then converts the mechanical energy into electrical energy. In order to maintain the normal power generation of wind turbines, the subsystem is a system inside a wind turbine for signal acquisition and control of wind turbine components. The wind turbine monitoring system is a wind farm that centralizes the signals and measurements collected by all wind turbine subsystems. monitoring system. For example, multiple subsystems such as fan pitch, yaw, cooling, and power generation monitor and control the working status of the fan in real time, and each subsystem generates a large number o...
