Monitoring system for wind power generation

Abstract

The invention relates to the technical field of wind power generation monitoring, and discloses a monitoring system for wind power generation, which comprises an information receiving module, an early warning module, a feedback module and a central processing module, wherein the information receiving module, the early warning module and the feedback module are wirelessly and electrically connected with the central processing module. According to the monitoring system for wind power generation, a temperature sensor monitors the temperature of a gearbox of a wind turbine generator, the temperature sensor transmits electric signals to the early warning module, the early warning module transmits early warning signals to the feedback module, and the feedback module analyzes the signals after receiving the signals of the early warning module, and starts an emergency braking module after the early warning signal is judged to be a temperature early warning signal, the emergency braking module starts to enable the wind turbine generator gearbox to perform emergency braking, and then the end point module enables the wind turbine generator gearbox to be powered off, so that damage to internal components of the wind turbine generator gearbox caused by too high temperature is reduced.

Description

technical field [0001] The invention relates to the technical field of monitoring wind power generation, in particular to a monitoring system for wind power generation. Background technique [0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean and pollution-free renewable energy source. It has been used by people for a long time, mainly through windmills to pump water and grind noodles. Realized, the gearbox in the wind turbine is an important mechanical component, its main function is to transmit the power generated by the wind wheel under the action of the wind to the generator and make it obtain the corresponding speed, the wind turbine gearbox is the wind turbine It is an important part of the gearbox, which is expensive, and failure will cause the wind turbine to shut down for a long time, causing serious economic losses. Therefore, strengthening the research on the condition monitoring and fault di...
