I apologize Giorgio for writing these things here,…
Below is a comment from my brother Pavlo,…
Yesterday I wrote that the network frequency has increased, which is not true, it has actually decreased, what is the explanation:
Solar inverters in practice “sense” the network frequency and try to create an identical frequency, well, in order for the electric current to flow into the network, the inverter raises its voltage above the network and this is how all solar inverters do it,… the result is an increase in the voltage in the network. On the other hand, certain power plants have to reduce their production by reducing the load on the generators, this probably also means a slight reduction in the revolutions - frequency,… in short, anyway, the network becomes unstable…

The iceberg was not the main culprit for the sinking of the Titanic, the main culprit was arrogance and hubris, because someone wanted to set new records.
The same story is behind the Spanish story of “green energy” and the collapse of the grid.

On April 16, for the first time on a working day, Spain produced as much electricity from wind turbines, sunflowers and hydropower as it consumed.
Five days later, solar energy set a new record, producing 78.6% of demand and 61.5% of the grid mix.

Yesterday, when it was time to set an even better record, an eclipse occurred.
Since it occurred because of the desire to prove the possibility of generating electricity with zero emissions, let’s call it the NetZero eclipse.

Tens of millions of people instantly became immersed in the fiction of “back to the future”
People were stuck in elevators. Subways stopped between stations. Gas stations couldn’t pump gas. Grocery stores couldn’t process payments…

It was one of the largest peacetime power outages Europe has ever experienced. And it wasn’t random. It wasn’t an unpredictable, or even a once-in-a-lifetime event.

Politicians, befitting their intelligence and the mentality of the people, immediately blamed “extreme temperature changes” and “a rare atmospheric phenomenon.”
…if such explanations worked in the Middle Ages, why wouldn’t they today? People are indeed more educated than they were then, but their intelligence isn’t. People still believe in black magic, astrology, witches, and wizards…

In a “traditional” power grid, dominated by heavy generators powered by gas and steam turbines, nuclear reactors, and water turbines, small disturbances are absorbed and smoothed out by the sheer physical inertia of the system. The heavy rotating mass of the generators acts as a shock absorber, resisting rapid frequency changes and stabilizing the grid.

But in a power system dominated by solar cells, wind turbines and inverters, there is almost no physical inertia. Solar cells do not produce mechanical rotation. Most modern wind turbines are electronically decoupled from the grid and provide little stabilizing force …

Otherwise, politicians and the “green agenda”, although they claim that the real reason will take several months of investigation, at the same time categorically deny any connection between sunflowers and windmills and the NetZero eclipse.:sweat_smile:

They also cite the poor connections of the Spanish electricity grid with the rest of Europe as one of the key factors why the NetZero eclipse occurred, which is absolutely not true. The best proof is yesterday’s event, when the frequency dropped to 49.85Hz throughout Europe!
In other words, we were only 0.1Hz away from having a pan-European NetZero eclipse, :sweat_smile:
since the oldest power plants, including one nuclear plant in Belgium, had already started to fail. This caused the French to cut off the connection with Spain.

From the graph in the previous post, it is clear that at the moment of the NetZero eclipse, Spain had too much solar energy, which it had nowhere to export, as there was too much electricity throughout Europe due to the sunny weather.

Of course, some of the sunflowers could be disconnected, but then there would be no new record😅

From the graph, I conclude that the wind just dropped to the limit where windmills usually stop.
But since the Spanish were chasing a new NetZero record, they probably tried to keep them moving, which consumed all the inertia in the network and pushed the frequency below the lower permissible limit, which not even the rest of Europe was able to balance…

The generators in the oldest power plants in Europe were probably less than a minute away from permanently breaking down, or burning out, due to spinning too fast in the “desire” to maintain 50Hz in the network…

Spot on Tone, as always. Thanks and thank your brother. Two generators here, enough for half our village

While I haven’t looked at Spain much at all or Europe in a while. Typically they shy away from storage. EIther they were trying to break the grid in an attempt to get storage, or they were trying to create dissent by trying to prove it doesn’t work.

In the US we call it frequency regulation. We can get around 50% RE on the grid without issues. In a large part because we switched a lot of production to Natural Gas. Coal and Nuclear both have issues cycling, where it just takes too long for them to ramp output up and down. Spain was pushing 70%…

The key is really storage so the power is available w.hen there is demand for it. Most of the time the old load following is used. Storage can be expensive in some but not all circumstances.

edit: I should note in the US, the capacity additions year over year, for wind and solar, are less the increase in demand over the last 12 months. It is -almost- there just 8 terawatts shy, which isn’t that much on the scale of what we use.

The US doesn’t track individual home type of installations, it just counts as efficiency or less electric demand. It isn’t worth tracking for the sake of ‘looking good’.

as with the actual throttle was yet a bit" high and low " work with the regulator, we made the throttle nearly round shaped…now it runs perfect in all rpm…remember i made the throttle oval shaped because i dont know the force and the way what the regulator is able to do…
the throttle has 37 mm diameter…the oval throttle , with a small movement, has allowed too much gas to pass through

Giorgio, the large surface area of ​​the throttle valve and the high vacuum create a fairly large force on the valve shaft, if I quickly and roughly calculate the force on a 37mm valve, it would be about 10 kg, … If you imagine the valve shaft, which is on a sliding surface, this requires a lot of force, and the oval valve has an even larger surface area, which means even more force and friction. The centrifugal regulator creates a lot of force, but we have to imagine that the spring force is equal to this, and the valve only has to be moved by the difference between these two forces, so it is very good that the valve is on well-lubricated bearings, which do not represent any friction

from my understanding, but of course it can be wrong, in a restriction (think on a venturi pipe) the negative pressure becomes higher, so a smaller throttle diameter is not less forced by negative pressure, because the vacuum stream sucks stronger…
when i think in a theoretical extreme and i have the throttle diameter of 50 cm, the suction will not be to feel much…only a thought for understanding of course…
also in water systems, when a piece of the tubing has smaller diameter, pression rises , so also in negative pressure systems, i think…but my conclusions can be also wrong…
the oval throttle has the thought behind that suction can act less on it, what from my sight should really be true, but has the drawback that with little movement can pass a lot of gas through. this was clear before, and to make the throttle more round was not a problem…
now the motor runs really like a bell, how my grandmother always said…

The “lock” word also works. As in lock in place from movement or changing.

The speed control should work like a balance, on one side we pre-tension the spring, on the other side the engine reaches the same force with centrifugal weights by increasing the speed, thus achieving balance,… The deviation to the left or right (closed or open) should be as easy as possible and with the shortest possible lever, thus we get very precise speed control.

A few days ago I bought 10 small bearings, maybe I will use them to mount the flap

in the moment i make experiments with different level hight of the water reservoir under the hair - sheep or horse- filter for keeping the filter medium umid during whole engine run…as we had observed with the garden tiller, that best filtering results are when air umidity is high…this keeps the filter material a bit umid continously…
yesterday i have readed a bit around in old topics and there was the idea from someone to add a water bubbler instead of water dripping and other methods in primary air…this but will be a very good solution for umidifying too dry secondary air for keeping the filter material umid…in my system no problem, because i add secondary air to the gas always before rubber tubing and hair filters to lower the temperature ( the valve on the motor intake before throttle block is only for starting easy )
in some historic plants i have seen they sended the gas also through water or thight over the water surface for cleaning (and than over oil surface)
adding some water in the hopper when having too dry coal helps a while ( or make a mess when it is too much) but after time the umidity disappears and the filter medium dries out too much…adding continous umidity to secondary air with a bubbler or other systems could resove the problem with too dry- or drying out- filter medium…

Giorgio,
I understand that higher humidity in the gas dampens the filter media and causes fine dust to stick to the media instead of being carried past the filter. But I have heard different ones mentioning problems with damp gas, two being difficulty lighting a flare and starting an engine. I use a water drip to give more power, but probably use less water than I could in order to avoid problems with damp gas. So, how should I reconcile the positives and negatives with damp gas. I have had a problem with fine dust and wonder if this is the way to go to eliminate it or not. What comments do you and others have about this concern?

My thods are, the gas shuld be as dry as possible. Water vapour can represent up to 10% of the volume of gas at 100% saturation, this means, if you have enaugh moisture for the droplets to start moisturising the filter (over 100% relative humidity-dew point), your gas is diluted 10%.

Then there are problems also with parts corroding.

But in an updraft, this is hard to acive, one of the reasons l always go downdraft. So since you got the gas diluted and damp anyways, might as well use what you got.

There is a venturi operated gas scrubber l designed for my Chevrolet Lacetti, will try to find it… worked well. Its well documented here, will try to find it.

Found it. As you can see, the venturi pulled a good amount if water with it but without the resistance of a bubbler. Constantly washing the filter.

I started washing the dust out of my char a ways back Steve. Kind of a PITA to have to dry it then but it eliminated a lot of problems I was having. Of course I just run updraft charcoal so simple anyway. I just use a water drip into the nozzle.

steve, when i worked recently with the motorcultivator, i added steam of the nozzle cooling water with a tube to the gas cooler, because there is a screw for washing…this for keeping the filter humid…this done for a while , and than for a while not, but seems not has had influenced the power…this moisture was a lot, and is not needed so much quantity, i think…when i opened than the horizontal hair filter, a lot of water comes out, condensed there…
when the moisture that keeps the filter humid, can condense in the filter or after the filter somewhere, is good…
what say our woodgassers here?
they have much moisture in the gas, on some builds is a moisture condenser near the engine with drain possibility, when i am not wrong…
i have never had so much moisture in the coal that i cannot flare or water drops appeared, but with a certain amount of moisture the spark plug gets a bit on it and this can make difficult with starting…so it requires some minutes ventilating with open hopper (observations with the garden tiller) and drying spark plug…
when this would be a problem, so a solution could be starting the engine without bubbler or whatever system, than , with a ball valve opening moisture producer and closing the direct air channel.
actually the filter medium, sheep wool or horse hair, i really press in the filter housing, and this is not a ostacle for gas flow…
further results when working with the engines, in the moment we wait for good hay weather, but is not yet…
the goal is best filtering as possible, of course…the throttle shows us the truth…
most experiments we make with the garden tiller, because runs often in the end of winter for keeping weeds down…sometimes air humidity is very high, sometimes really dry days…and a additional problem is that on so little mobile engines cannot be packed a lot of filters on…recently my son tillered, power was not so good, sometimes ignition interrupted a bit, but maybee normal, old motor and ignition…we suspected too much moisture, hearth clogg up, and so on, but always the same symptoms, only some ignition interruptions more… at least it was not to start more, .it comes out than that the coil began to become bad…we changed it, and actually runs fine…also this is a point when making observations and changing things in the gas system…is the motor itself ok in all his parts, otherwise there are easy wrong conclusions…
also the idea from kristijan with a carburettors venturi is interesting…
