Diesel conversion to 100% chargas

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.
Position Lock.

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

For the last couple years I’ve been looking for my stripper pliers with the green handles. Now I know where they are :smile:
