My guess for not meeting service would be that for a period you were slightly under voltage. Frequency shouldn't have been a large problem, basically everything is built with tolerances to a higher or lower frequency, but the voltages will really cause mayhem on the transformer side once the power is delivered to locations. A few volts on the top end can be tens of volts on the low end. Unsure how realistic their grid simulation is. It would be interesting to have to chase the damaged grid, with substations going down dropping demand on your end, and then as they come back online you need to follow it up.
Sounds like you have some experience in power distribution. That is definitely outside my realm of experience, so that is a pretty interesting take on this. I think that might get into really complex simulations for the average user! Would be cool to see it more detailed though.
@@GWHacketts I don't actually hold experience in the field, but I am trained in electronics and mechanics, and through self-teaching have a rough understanding of tolerance conditions for a "circuit". If voltage drops, current typically increases in a fixed-power system. This can cause overheating on connections and inside high-resistance components on both supply and demand sides. While the voltage wasn't terribly low in your case, tolerances on the grid would have to be fairly strict in order to provide sufficient voltage to even the last house on the furthest end of the line.
Normally it would be governered by other spining generators. Since its a power outage situation i believe you might be the only generator on the grid. Since you are excedding demand the generator doesn't have enough resistance to reduce the speed of the turbines. So chasing the demand might be easier for this challenge.
Oh I see, so if I put resistor banks on do you think it would stay at the correct RPM? Idk I just thought that if you are demanding a certain RPM it should stay at that RPM. I'll have to try that in the future, just don't want to destroy the resistor banks!
@@GWHacketts In the real world, rotational inertia keeps the grid frequency quite stable, especially if the grid gets larger. Primary control loops in generators keep the frequency between 49.8 to 50.2 (automatic systems apply 0% to 100% output power in this range) If the mains frequency drops below 47.5Hz or climbs above 53.5Hz, automatic breaker sin power plants are supposed to open the main breaker and throw the power plant offline. In the real world, you want to close the main breaker when the syncroscope is at the top position and is slowly running in the too fast direction. In the present state of the game, your power plant seems to be the only energy provider on the grid (with the exception of a magic existing network you can sync to) and increasing or decreasing the field excitor and increasing or decreasing the speed(RPM and HZ should be connected, but in the game they are 2 different actions) should not be used, and you should use resistor banks to make sure consumption and demand are in order to prevent the mains frequency from getting out of control. The game also has a separate state for mains breaker connected and being in sync, this is not how it is in real life, both states are the same in real life. Once you close the main breaker, you get in sync. If your steam turbine runs dry, it will be pushed like a motor until automatic circuit breakers disconnect the plant for being back-fed
@@FerrybigGaming That's a great discussion on how things should actually work! I am not sure how hard it would be to incorporate something like this, but it would definitely add to the realism. I agree that RPM and frequency should be tied, and speed of the turbine would be controlled by the RPM as well. I mentioned some of this stuff in my videos, so I am not sure if he is planning on creating those elements, or he just rushed to get stuff done.
Yeah a couple of times in other playthroughs, I would raise Rx coolant pump frequency, and then it would cause a massive spike in frequency, so I just took it slow, which helped. Frequency still went up at times but not as much. The only problem I have with the RPM is that if I set it for 3060, then why would it increase. Maybe this is where navy knowledge does not apply to civilian reactors. I would have thought these turbines would auto regulate the speed and frequency to keep it at 51Hz. Thanks for watching!
I think you left the condenser freight pump on! Also does the vacuum pump need to run the entire time? I've seen some players get it to vacuum then shut off the pump. Edit: 20 minute mark and you turned it off. 😆
Yeah I sometimes forget to turn things off lol Then I end up getting weird results, and I scratch my head for a bit, but after checking parameters I figure it out lol So i read on the discussion that you can turn it off, but in actual life if you put a vacuum on the condenser and turned of the pump or whatever is drawing the vacuum, I would think the vacuum would just go away. So, I just leave it on, but I did read on the discussions for the game you can just turn it off.
Generally speaking, a condenser will passively pull its own vacuum in nominal operation. It might not be what's considered 'vacuum' by atmospheric standards, however it is a comparative negative head draw on the steam loop caused by the condensing of the dead steam. Water expands in a factor of 1700:1 when boiling off, so, to have a significant quantity of that volume 'collapsing' will induce a vacuum. - Additional mechanical pumps are still used in order to draw out non-condensable gasses, but the bulk volume of condenser vacuum comes passively from steam condensate.@@GWHacketts

Well, i dont know if its needed to sync turbines in this game but irl its very important
No, you do not need to sync turbines in this game. I agree bad things will happen if not sync'd up, like FIREBALLS!

Probably was due to frequency too high (service compliance)
