Abstract:As the demand for wind energy continues to grow at exponential rates, reducing operation and maintenance (OM) costs and improving reliability have become top priorities in wind turbine (WT) maintenance strategies. In addition to the development of more highly evolved WT designs intended to improve availability, the application of reliable and cost-effective condition-monitoring (CM) techniques offers an efficient approach to achieve this goal. This paper provides a general review and classification of wind turbine condition monitoring (WTCM) methods and techniques with a focus on trends and future challenges. After highlighting the relevant CM, diagnosis, and maintenance analysis, this work outlines the relationship between these concepts and related theories, and examines new trends and future challenges in the WTCM industry. Interesting insights from this research are used to point out strengths and weaknesses in today's WTCM industry and define research priorities needed for the industry to meet the challenges in wind industry technological evolution and market growth.Keywords: wind turbines (WTs); condition monitoring; fault detection; destructive tests; non-destructive tests; subsystem monitoring techniques; overall system monitoring techniques; state of the art; new trends; future challenges
Wakui and Yokoyama [124] developed a sensorless wind-speed performance-monitoring method for stand-alone vertical-axis WTs using numerical analyses in a dynamic simulation model. Yang et al. [113,125,126] and Watson et al. [122] proposed a wind turbine condition monitoring technique (WTCMT) that uses the generator output power and rotational speed to derive a fault detection signal. The technique is based on a detection algorithm using a continuous-wavelet-transform-based adaptive filter to track the energy in the prescribed time-varying fault-related frequency bands in the power signal. A probabilistic model of the power curve based on copulas was developed by Gill et al. [127], for CM purposes. Copula analysis is likely to be useful in WTCM, particularly in early recognition of incipient faults, such as blade degradation, yaw, and pitch errors.
In most modern WTs, SCADA systems are now common. The WTCM using SCADA data analysis is cost effective (data collection and sensor networks already in place) and reliable because it relies on the interpretation of SCADA data [132]. The SCADA system collects information extensively from key WT subassemblies using sensors fitted to the WT, i.e., anemometers, thermocouples, and switches. The operational data reflect either turbine status or measurements of signals, such as wind speed and direction, temperatures, currents, or pressures. This information can effectively reflect the real-time condition of a WECS, and by analyzing SCADA data, the relationship between different signals can be observed and the health of WT components deduced [133]. Neural networks and fuzzy logic are other examples of the common tools for data analysis. An overview of WTCM based on SCADA data analysis is presented in Figure 12.
Here are some photos of the workshop. There were 8 participants plus me. We built a 2.4 metre diameter 24-volt turbine from the Recipe Book. Weather was great and we even got a little wind on Friday so the machine produced a few amps.
The English units edition is not a simple conversion of the sizes into inches and AWG etc. It is a subtly different set of designs that works with these subtly different magnet and wire sizes. My advice is not to mix the two books although the result will kind of work if you do. Choose one system and follow the recipe for that.
There are several sections of general interest, but most of the book is very specific to the stages of construction, and has dimensions for each size of turbine tabulated alongside diagrams and text. At the end you will find a set of basic drawings of the four main types of head for the turbines. The drawing show the metric turbines and so the magnet shape appears slightly different, but the dimensions listed in the tables are all in inches.
There is plenty of scope for hurting yourself or others when building and operating small wind turbines. You follow these guidelines at your own risk! I am not going to fill this manual with all the safety notices and disclaimers that make many manuals unreadable. But I will point out the main hazards up front.
Erecting towers can be deceptively tricky and many people have dropped wind turbines from a height in the attempt. Needing a new set of blades would be a setback, but nothing compared to crushing a child. Keep everyone out of the fall zone, and pay attention all the time. Do not erect a wind turbine tower in a public area where people congregate beneath it.
Battery-charging wind turbines do not generally create any risk of electric shock, but bear in mind that when they are running fast and not connected to a battery the voltage they produce is much higher than nominal battery voltage. Dangerous voltages can arise in exceptional conditions (especially with 48-volt systems), so it is best to keep junction boxes closed.
The amount of energy that you will get from the turbine depends mostly on two things: the diameter of the blade rotor, and the exposure to good winds. The power rating of the alternator in watts actually has very little influence for most of the time, because full rated power is only available in stronger winds. The rest of the time the power output is limited by the wind and by the size of the rotor.
3-phase AC power from the wind turbine is converted to DC power by a rectifier. (Only one DC wire is shown to simplify this diagram but you need two.) In most cases the DC is then made into single phase AC power (normal household electricity).
Small wind turbines are a good way to produce electricity in a windy place. Wind energy is highly dependent on the wind speed, so it is a good idea to erect a tall tower to reach the best winds. The turbine needs to be well above surrounding trees and buildings - not just at rooftop level. If the location is not windier than average, then small wind is probably a waste of effort but there is no reason not to do it if you just want to do it. There is no reason to drive around town in a big four-wheel drive vehicle, but people do that. If you need to build or buy a small wind turbine, then that is fine too (even better!). But you need to understand that it will not save you any significant money (unless the site is really windy). It will be less environmentally damaging than a four wheel drive, but it will not immediately 'save the planet'
The wind turbine is rather like an engine whose throttle you cannot control. If there is no wind then it will not turn at all, but if the wind is strong then you have to give it something to do or it will overspeed and run wild. If the wires are disconnected from the turbine then the voltage will shoot up until it can damage lights and electronic equipment.
If you are feeding the mains grid without batteries then Power-one Aurora, Ginlong and Enasolar are good options for inverters. Take care that you protect the inverter from over-voltage with a protection box. These grid-tie inverters can also be used on some stand-alone inverter systems. This is called AC coupling of the wind turbine to the battery.
In the electrics section about winding coils for the turbine I have presented a table of different options for different battery voltages and also for the grid-tied inverters. I offer a couple of options because there is some flexibility but you may need to enter a table of power/voltage data points into the inverter's program to suit the winding you have. email me for guidance if you wish.

I am replying to R Martins comment regarding class action from affected people, like myself, living only 600m from Hepburn Wind industrial turbines. The main reason is MONEY. The wind industry and courts like V.C.A.T. know only too well that people like myself do not have the funds to fight proponents and government departments, namely Sustainability Victoria.
Why is there nothing done about the noise of industrial wind turbines? Is it because there are too many people on the take as the industry is a fraud & there are wind weasels & greentards that are nothing more then corrupt (Labor & Greens included)?
Mr.Cooper is a wonderful man. He speaks only the truth along with Dr, Laurie and several politicians who dare to oppose wind turbines. A lot of people think they work only with wind and do not realise they are an industrial machine made of CO2 emitting materials and emit noise. 2ff7e9595c
