Power consumption spikes on fuse reset

[dimmu1313]

So it seems this game is trying realistically to simulate in-rush current by spiking consumption on fuse reset (I'm an EE irl so this is something I'm very familiar with). I needed to generate some emergency fuel and my refinery draws just under 60MW. So I connected 2 biomass generators at 30MW each, and when I reset the fuse, theres a huge consumption spike thats about double the expected power draw.

What's up with that?

I haven't seen a capacitor-type device that would smooth in-rush current but it certainly seems that the amount of power i need at startup is way higher than what the listed power draw is. I've noticed that happen a lot when I started adding assemblers and manufacturers at my main factory; once the fuse tripped when I draw a bit too much power, I'd add another coal generator, but then there was a power consumption spike that was way higher than that additional 75MW so the fuse would continue to trip even though the net continuous draw should be lower than my new produced power amount.

Is this a bug or by design? If it's by design, it doesn't make sense that I should have to have >2 times more power capacity than my peak running draw, unless there was some kind of capacitor feature. Without a capacitor-type device, I have to spend a lot of time and resources expanding my power supply chain to a level that far exceeds what I actually need.

I think it's the max of all your machines toghether that makes the spike that high, so when you turn them on all machines take power for like 1 second before going back to standby mode if they don't do anything.
That's what I think is the case atleast.

Belts don't power down. What's happening is all your machines are queuing up instead of them acting at random. They all turn on at the same time, causing a gigantic spike that kills the network. Your maximum power drain will always be equal to everything powering on at once.

Any dips or spikes in demand are due to bad factory ratios or maxed out storage. There's no absolute need to make all the ratios and such perfect, just try to keep some overhead and you'll be fine.

It is possible to run a factory all the way up to a consistent 100% demand with no spikes or dips whatsoever, but it is an extreme challenge to overcome. Every ratio and surplus product must be perfectly accounted for, not a trivial task at all.

Its by design. I am not sure on capacitance, and other EE values and such. However, spiking has always been a thing. I believe its meant to simulate cold start load, rather than always be median load.

I had to put some of my bigger machines manually into Stand-By buy hitting the button on them.

It is the thing, that on repower all online machines use their maximum of energy until they notice they are on standby.

THIS is also in RL so. If my Fuse in the house turned power of (because we plugged one maschine in (Staubsauger, do not know the englisch word out of my head) we have to deconect it (or turn it off) to put the fuse on again. Or I have to turn off my Computer which is on the same circuit.

When you first switch on everything kicks in at once. What I do is have sections I can disconnect and reconnect easily, and try to not let the power need exceed capacity too often.

happens in real life also power spikes.

if your game energy is right this should not be a problem if it is then you not produce enough energy.

Thanks. I'll keep in mind that at breaker reset, the max power draw is immediately the sum of every connected machine running at max consumption all at one time.
