Wind farm icing monitoring and early-warning device based on electromagnetic resonance principle

Abstract

The invention provides a wind farm icing monitoring and early-warning device based on the electromagnetic resonance principle. The device comprises an icing probe and a host computer. The icing probecomprises a shell and a core monitor module. An annular cavity is formed in the shell. An annular electric hot plate is fixedly installed in the annular cavity. A fan is fixedly installed in the center of the bottom of the shell. A plurality of air outlet holes are formed in the top of the shell. A plurality of air inlet holes are formed in the bottom of the shell. An installation base is fixedlyinstalled in the center of the inner side wall of the bottom of the shell. The wind farm icing monitoring and early-warning device based on the electromagnetic resonance principle is reasonable in designing, and a closed-loop oscillation system can be formed by an electromagnetic vibrator coil of the icing probe and an alternating-current amplifier of a solver; when in steady-state work, an outputsignal with a fixed frequency is generated; during icing, a fixed vibration frequency changes; when the thickness of an ice layer on the core monitor module reaches a preset value, and an icing warning signal is provided; and monitoring is accurate, and the monitoring effect is good.

Description

technical field [0001] The invention belongs to the technical field of icing monitoring, in particular to an icing monitoring and early warning device for a wind farm based on the principle of electromagnetic resonance. Background technique [0002] In order to better ensure the safe and stable operation of wind farms, real-time monitoring and early warning of the icing status of wind turbines is required to predict the icing trend of wind turbines in advance, so as to determine countermeasures. However, the existing wind farm icing monitoring And the monitoring effect of the early warning device is not accurate enough, and the monitoring effect still has room for improvement. Therefore, the present invention proposes a wind farm icing monitoring and early warning device based on the principle of electromagnetic resonance. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides a wind farm icing monitoring...
