worst-case scenario engineer

Power system protection engineer. Professional worst-case scenario guy. Rich people aren't smarter than you. he/him. Infrastructure should not be for-profit.

OK so at some point I was asked for resources to learn more about protective relaying, so in this thread I'm gonna drop videos and the like that I think are decent for that purpose

@BryceJohanneck @gator_91 Depends, how critical is whatever that device controls?

[worst-case scenario engineer @worstcaseeng]

good thread

[mini-linux @gator_91]

(1) With the blackout in Spain, much has been said of late about generator operating characteristics, system frequency, and stability. I’d like to take a bit of time and offer some simple engineering relationships I think are useful to keep in mind when speaking on these topics.

@PaulTassi @Forbes Paul if you could put 300 hours into TFD you really need to give Warframe a proper chance lol

[worst-case scenario engineer @worstcaseeng]

@Umbrance1 @PaulTassi to be fair it's not really a space AK it's just an AK that you can bring to space

[worst-case scenario engineer @worstcaseeng]

@GhostRabbiit @PaulTassi good Drifter fashion

[worst-case scenario engineer @worstcaseeng]

@CT10343 @PaulTassi unironically yes

@DumasMoura @mailmanbabygame @PaulTassi "this game only makes sense in an altered state (positive)"

[worst-case scenario engineer @worstcaseeng]

@egreghost extremely difficult to solve, especially as technical experts are in short enough supply as it is, and the government jobs are largely (correctly from what I hear) believed to suck

@evcricket @xiaowang1984 @nicknet100 @GlenneDrover @joelmcourtney @LesleyG78347579 @DavidOsmond8 @AvivCoko @jm493_au @flexibledragnet In the exact same way that utilities and power sellers ignored the climate impacts of fossil fuels, the market has found out how to make money on solar and wind and is recklessly driving systems to a fragile state, and those of us who know are largely ignored

@evcricket @xiaowang1984 @nicknet100 @GlenneDrover @joelmcourtney @LesleyG78347579 @DavidOsmond8 @AvivCoko @jm493_au @flexibledragnet This has nothing AT ALL to do with the interconnection process or individual IPPs, this is a broad, regional system operations issue that has been constantly discussed at every major system protection conference for the last decade. It is not solved

[worst-case scenario engineer @worstcaseeng]

@evcricket @xiaowang1984 @nicknet100 @GlenneDrover @joelmcourtney @LesleyG78347579 @DavidOsmond8 @AvivCoko @jm493_au @flexibledragnet Yeah lots of people are interested finally, what are they doing about it? We getting syncons finally? Movement on the flywheels Australia was originally trying out some years back? What's being deployed at scale?

[worst-case scenario engineer @worstcaseeng]

@evcricket @xiaowang1984 @nicknet100 @GlenneDrover @joelmcourtney @LesleyG78347579 @DavidOsmond8 @AvivCoko @jm493_au @flexibledragnet The issue is that fault current is *not* being dealt with, that's why these concerns exist, and having talked to them at various times on here I'm pretty sure that is a part of the concerns yeah.

@GlenneDrover @nicknet100 @xiaowang1984 @evcricket @joelmcourtney @LesleyG78347579 @DavidOsmond8 @AvivCoko @jm493_au @flexibledragnet Frustrating to me as a transmission nerd that every time I catch an AEMO presentation on system protection it's focused on the distribution side lol

[worst-case scenario engineer @worstcaseeng]

@evcricket @xiaowang1984 @nicknet100 @GlenneDrover @joelmcourtney @LesleyG78347579 @DavidOsmond8 @AvivCoko @jm493_au @flexibledragnet I'm not sure what you think you mean by that but that's an incredibly dismissive-sounding response to someone trying to explain a complex engineering issue to you, as you requested

[worst-case scenario engineer @worstcaseeng]

@GlenneDrover @xiaowang1984 @ChomskyChannel @evcricket @nicknet100 @joelmcourtney @LesleyG78347579 @DavidOsmond8 @AvivCoko @jm493_au @flexibledragnet It's at least before I saw it proposed, I'm not sure how extensive their deployment of it has been since then

[worst-case scenario engineer @worstcaseeng]

@evcricket @xiaowang1984 @nicknet100 @GlenneDrover @joelmcourtney @LesleyG78347579 @DavidOsmond8 @AvivCoko @jm493_au @flexibledragnet it's more like the 2003 North American blackout - too many pieces of the Jenga tower removed, to the point where the wrong failure at the wrong time leads to a cascading blackout. Something working under normal or even N-1 conditions is no proof of resiliency

[worst-case scenario engineer @worstcaseeng]

@evcricket @xiaowang1984 @nicknet100 @GlenneDrover @joelmcourtney @LesleyG78347579 @DavidOsmond8 @AvivCoko @jm493_au @flexibledragnet And even the ones that do work adequately (mostly just looking at line current differential systems here) don't have functioning backup systems the way they were designed to have. I think it's critical to understand here that this isn't a concern about some immediate failure,
