Description

Wind power generating motor on-line monitoring instrument

Technical field

The utility model belongs to green energy resource, wind power generation field, especially a kind of wind power generating motor on-line monitoring instrument.

Background technology

Wind energy is clean energy resource with fastest developing speed in the regenerative resource, also is the renewable resource that has large-scale development and commercialized development prospect most.Along with energy resource consumption is growing, environment further worsens, and countries in the world are all the important component part of the reproducible green energy resource of development as the national strategy of sustainable development.Wind-power electricity generation is the main mode of Wind Power Utilization.From 2007, wind-power electricity generation became the 3rd big newly-increased generating power supply after firepower and water power.According to the statistics of global wind energy council, past 10 years global wind-power electricity generation industries balanced growth reaches 25%.And the wind energy development develop rapidly of China has become the maximum wind-power market in the whole world.The wind energy turbine set single-machine capacity has increased to MW class both at home and abroad, and therefore the large quantities of MW class novel wind generator of China group drops into the large-scale production operation hastily in recent years, and quality and operational reliability problem are outstanding, have increased technology and economic risk.Because the restriction that wind-resources distributes, wind power plant is distributed in desert, mountain area, the pasture away from the city more; Along with the development and utilization of wind energy on the sea, coastal waters or beach wind power plant will become the important development direction of following wind-powered electricity generation, and this has brought great difficulty all for the Operation, Administration and Maintenance of unit.In order to safeguard wind energy turbine set with reasonably runing and improve, improve operational efficiency and the reliability of wind power generating set, it is essential that every typhoon power generator group operation conditions is carried out status detection.

Wind power generating set is to utilize wind power plant that wind energy is changed into electric energy, to satisfy user's electric power requirement.Aerogenerator generally is installed in the open air, inclement condition, and overhead tens meters high, so wind power generating motor and blade are easy to break down.Along with the increase of wind-power electricity generation installation amount, the maintenance of aerogenerator and maintenance have become the problem of people's growing interest.The maintenance mode that adopts has two kinds at present, and a kind of is manual inspection; Another kind is to utilize the on-line monitoring instrument to detect, and by data transmission system testing result is transferred to Surveillance center.First kind of maintenance mode need expend big human and material resources and financial resources, and second kind of maintenance mode is easy, real-time, but the main dependence on import instrument of domestic present maintenance mode.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of easy and simple to handle, real-time wind power generating motor on-line monitoring instrument is provided.

The utility model solves its technical matters and takes following technical scheme to realize:

A kind of wind power generating motor on-line monitoring instrument, its major technique is characterised in that: involving vibrations sensor, wave filter, A/D converter, single-chip microcomputer, warning circuit, GPS global location module and wireless transport module, described vibration transducer links to each other with wave filter, described wave filter links to each other with A/D converter, described A/D converter links to each other with single-chip microcomputer, described warning circuit all links to each other with single-chip microcomputer with GPS global location module, and described single-chip microcomputer links to each other with wireless transport module.

And described A/D converter adopts the MAX1202 of 8 channel serial, 12 A/D conversion chips.

And described single-chip microcomputer adopts the AT89C52 single-chip microcomputer.

Advantage of the present utility model and good effect are:

1, the utility model is gathered the vibration signal of wind power generating motor by vibration transducer, vibration signal is carried out digital filtering handle, spectrum analysis obtains spectrogram, the waterfall figure of vibration signal, whether frequency spectrum takes place unusually abnormality to be alarmed under the running status of observation motor.

2, the utility model is reasonable in design, utilize the mode that detects vibration signal, detect motor, gearbox, transmission shaft and main shaft bearing, and utilize the pattern of wireless network and GPS global location signal is transmitted and to locate, realize the wind power generating motor on-line monitoring; The utility model is easy and simple to handle, and is real-time.
