Home wind farm: good or whim?

In the article in the examples, only foreign developments of wind power stations are given, which by default will be very expensive and, accordingly, economically unprofitable. But there are domestic wind farms that have already proven themselves from the very best side. They are several times cheaper than foreign analogues with the same technical characteristics. And in general, the appropriateness of using wind energy in generating electricity is a controversial issue in terms of economy, but it is relevant as an important part of various serious environmental projects. And if we use modern developments of domestic inventors, then the economy of this whole process is not becoming such a critical parameter.

Having carefully read the article, I come to the conclusion that the article itself by value does not pull more than 30 percent. Before authors advertise ready-made installations, I would like to think again about simple, inexpensive home-made products. For the manufacture of such a simple device, you can use an engine from a car wiper that rotates brass threaded shafts. Further, these shafts can be connected to any "unit" that you want to automate at home. For example, opening the gate. So the power of such a wind turbine will be enough for many small things. And the costs are minimal. The main thing is golden hands, a little desire and a bright head.

I understand that you are wind energy enthusiasts))))))) But they told you in Russian that the main drawback of wind energy is its low concentration (flux density) and there is nothing to be done about it !!! Therefore, it is necessary to build giant wind farms and “wind dams” with fairly modest indicators. No, of course, wind energy can and should be used, but one should not expect some kind of super-efficiency! Especially if you live in a normal place, where there are no constant strong winds (yes, people don’t settle in such places, it’s very uncomfortable!).

I have a 65 Watt solar panel. Homemade windmill with a 750 W generator from Mosvich. Two batteries with a capacity of 62 A.h. each. And the uninterruptible power supply from the computer that was given to me on the occasion of its unsuitability (like they stopped taking charge from time to time). For 2 years, I have been using this particular energy. I have a washing machine connected to the Chubais network and, if necessary, again I connect the inverter Resanta 190 A. to Chubais electric welding.
Everything else is consumption, I have autonomous.A refrigerator, a TV, at the same time sometimes lights up 9 lamps 95 W in the evenings. The TV turns off when we just sleep. Comp forget to always turn off. So do it, go for it and don’t listen to propagandists to buy electricity at inflated inflated prices from speculators.

article clearly paid, "Chubais.", they say, suckers! you cannot afford to become free from the state. Of course, if every citizen in the countryside wants a chickenpox (for his modest needs) - this is an outflow of money !!! How is Kozma Prutkov: see the root. And the Bible says: the root of all evil is love of money.

About the efficiency of windmills. It is this question, or rather ignorance of this issue that gives rise to a bunch of fables and really hinders the use of wind energy wherever possible. The efficiency of windmills is trying to count in the same way as in cars. In cars, this is the result - the efficiency of converting gasoline into movement. And the more movement when burning a unit volume of gasoline, the better. And the efficiency is higher. This is understandable: gasoline is expensive and constantly rising in price. And it’s not a hunt for anyone to burn it in vain. With the wind - another system: the wind is absolutely free! All how much it blows! And no matter how much you convert it into heat or electricity - it is all yours! In the form of net profit. You can only calculate the cost of construction and materials and find out when it will pay off. And they consider it purely mathematically - as the coefficient of conversion of wind into electricity. The cheapest generators are from decommissioned equipment. High speed. So, the speed of rotation of the windmill should be maximum in all calculations. And the fastest windmills are propeller type. And noisy, and break with their other flaws. But most firms do only them. Because they consider the wind gasoline, on which their installations work. In fact, this is a delusion. Just a disaster! According to their calculations, low-speed windmills are not profitable to do, because you need to make a multiplier to accelerate the rotation of the windmill shaft and achieve the high revolutions needed by the generator to generate current. That's what the buzzing and breaking propellers do. I bought one familiar from such a windmill with one blade already! Everything for rotation speed. He buzzed terribly! But not for long. After three days of work, his high-speed blade flew off, and behind it the tail! The machine was not designed for Siberian gusty winds. And it was over the forest! But while it worked - there was a lot of current! If we proceed from the fact that the wind is free, and even if not all goes into the current, then it is more profitable to make a slow-moving windmill. And it will not make noise, and work for a long time, and supply current in a more smooth way. And you can make any output speed. Also put a multi-speed transmission from racing bikes. Semi-automatic: with a large wind, you can change gear ratios and adjust the rotation speed and current supply. All fresh ideas require fresh thoughts. And a non-standard approach.

Tell me, who knows how to automate the increase and decrease of the load after the inverter of the wind generator. While doing this manually.

I propose a new method of power generation, in detail on the website ECOGENERATION.RF

Oleg, put the battery after the generator, and then the inverter

Obtaining wind energy using a sail scheme (blades of a wind turbine,

there are various types of sail forms) and chasing after the wind, it reminds a joke - a civilized European asks a native, how do you eat? But the wind will blow and the fruits will fall to us. And if it does not blow? Well then crop failure!

There is one idea in solving the use of the dynamics of the air as a result of the rotation of the Earth, the difference in temperature and atmospheric pressure in height, i.e.factors determining the horizontal and vertical movement of air flow - renewable energy. I created an airflow control workflow regardless of the strength and wind rose. The ADES-PIPE aerodynamic power plant, an autonomous, environmentally friendly and safe installation for generating electricity anywhere in the world, at any time of the year or day. Does not need any fuel.

Why didn’t our windmills take root? The fact is that in Russia and the countries of the former Soviet Union, winds of industrial power and blowing constantly - not in principle! There are windy places where it blows hard. But the gusty wind. In addition, all of our wind - embossed, or rather - is tied to the surface of the earth and from this has various twists. It blows not in a straight line, but from different angles, often changes course and is extremely impulsive.

So my friend put a small windmill with one blade, factory-made, so three days later this blade was torn off, and the tail to boot! It hummed like an old vacuum cleaner both from the wind and from braking against the air. It was constantly spinning, but it always worked for less than a minute, then it braked sharply and turned. He worked in a constant mode of unwinding - braking and turning the wind system. Broken. And he worked in design mode in seconds. The generator could only slightly warm up a small heater. And even with a strong wind, he did 10-30% of the work that was designed. At the same time buzzed - one hundred percent! And he hummed most during acceleration and braking. With a dense wind stream, it is almost inaudible - it works cleanly and without noise. But I had to stand at him and watch for about an hour. Basically, he was engaged only in acceleration and braking and buzzed.

In general, paddle windmills are in principle not applicable to overhead lay winds. And there were no others. Because before there were no windmills. What can be done in Russia and its environs? - Windmills and watermills. Water - it’s understandable to make a dam on a stream. Windmills - can be made from the rear axle of a cargo or passenger car and multiple blades by combining them in a circle. A slow-moving system and the wind have to wait, but it works for a long time and grinds the flour. - For the generation of electricity, long-lasting and slow-moving windmills with a vertical axis of rotation are best. Experts are dissatisfied with their low efficiency and high material consumption, but for the private trader this is not important, and the wind is free and any work already generates income.

The most suitable solution is wind sails. They are different, but they work with low winds, medium and high. Sailing winds do not suffer from heavy winds. They can work at different angles to the wind, which the blades cannot. You can provide a brake system. The size and power of the windmills - any. And you can have several in different places to charge the batteries, or one big one. To generate mains voltage and to supply it to the network, you need a battery system, an inverter and a controller. In addition, the system must be certified in energy sales, which is unrealistic. Therefore, it is better to generate energy for yourself. Triangular sails with a deflection of the canvas on the largest side. It is precisely to produce and operate them that is profitable, since they have the most suitable characteristics for utilizing our winds. And the residents themselves often make such windmills. Buying the whole system is expensive, you can only take the original generator with an inverter, and do the rest yourself. It will be cheaper. Now many would drive home-made cars, but they would not be allowed on the road. And here - please! What did, then set. And let the current generate.

There is one problem unknown to the author: a kilowatt hour is a kilowatt multiplied by an hour, that is, kW * h or kWh, not kilowatt per hour, i.e. divided by an hour or kW / h, as he writes. That is, kilowatt hours is work, or power multiplied by time. A = P * h.And power divided by time is some kind of nonsense, a quantity unknown before this author to science. It turns out that we have a new Maxwell. As they say, a nuance, but this nuance betrays that the author is an ignoramus in physics, then how can one believe his article?

Regarding autonomy, my attitude to wind turbines as to the wireless Internet is the main problem, not even low productivity, but rather instability. One thing is 100 Mbit / s is stable, and another thing 100 Mbit / s is unstable, jumping from 0 to 100. Electricity from the power plant is stable, and even more powerful than from the twigs.

Such nonsense was written .. To connect a house 150m from the line, I need to put three single-post columns, one anchor (two racks) and attach a “leg” to the supply column, for a total of six supports, each 4900 rubles each, buy 160m SIP 4x16 at 80 rubles per meter and another electrical installation valves for 4.5 thousand plus a meter with a SIM card for 6.5 thousand and a power shield (cost 5.5 thousand) (in prices at the end of 2015) + work (with a drill) the same amount plus a project and etc. total to connect the house to me They counted at least 165 thousand children. After that I will pay 400-500 rubles every month. A single kilowatt wind generator, with a mast, inverter and a couple of akkas at 200Ah / 12V will cost about 125 thousand, and you can add to it a gas station for thousands of 15 per 1 kW (for some work, just in case). Everyone can look at the table of power consumption of electrical appliances and calculate how much energy he needs, and I pay for a month for 140kW -160kW (old machine without drying, dishwasher, old refrigerator, computer, 2 TVs, lighting 2 rooms, iron, plus other small equipment), that is, I consume about 5 kW per day, that is, on average, a wind generator should work 8-16 hours a day - this is real. And it’s really possible to do energy reduction.

An article from Rosenergo provocateurs is one-sided and untruthful, there is nothing better than giving up on the farm energy networks (these robbers).
