US/Canada Power Outage Task Force Event Timeline

Posted by michael on from the alone-in-the-dark dept.

bofus writes "The U.S./Canada Power Outage Task Force issued the Aug. 14, 2003 Sequence of Events at noon today. While no conclusions are drawn at this point, it does paint a pretty good picture of what happened and when it happened."

  1. The blame game by trolman · · Score: 5, Interesting
    The really bizarre part that has not been explained is that the frequency deviated. I saw frequency deviation alarms on my equipment (ups and pdus) on the data center floor in NY, NJ, and CT and this is the first time in my 20 years that this has happened. A glaring ommission is is that PJM stayed up as an entity. Kudos to PJM.

    The blame will be put onderegulation and lack of government oversight.

      Well, what exactly causes frequency deviation? I'm not terribly familiar with it, and I can only imagine that there are a few things associated with it?

      The frequency changed as generators tried to cope with overloads. In general, the only way to increase a generator's power output is to make it rotate faster- i.e. increase the frequency. Normally this happens on a very slow scale (generally variations of +/- 200ppm excursions over the course of day, with an average of 10pmm or so during the same period to keep clocks accurate). Obviously this is somewhat coordinated among different generation plants, since they need to be more or less in sync.

      Anyway, severe load changes are likely to cause severe frequency changes, severe being +/- 10000 ppm or more. Naturally, this isn't helpful, and weird low-frequency feedback effects can happen as generators in different areas try to react to each other, and to the radically changing loads.

      You can try this for yourself. Get a little bitty electric motor. DC will work fine. An electric is basically the same as a generator, and if you turn the motor, it will generate an electric current.

      Spin the thing by hand and see how easy it is to turn. Pretty easy. Now, short out the connections to the motor and you will find that it's considerably harder to turn it. There's some resistance to the turning there.

      When you shorted out the leads on the motor (which is operating as a generator), you've increased the load on the generator from nothing to something very large. And, as that load increases, the generator gets harder to turn.

      Since the frequency of AC power coming out of a generator is set by the speed at which the generator rotates, it's simple to see that if the load makes the generator harder to turn, it will slow down because of that load. That makes the frequency of the AC coming out go down.

    Hopefully this is something that they can actually use to learn from. Seems to me that they should put safeguards in between each one of these events. Because if just ONE of these events could have been stopped, it would have stopped the whole east coast from losing power.

    1. Re:Future Prevention by CoffeeCrusader · · Score: 2, Interesting

      yeah, but that would have meant, that the power providers had to provide money too. All of this could have been prevented with a bit more modern equipment. And modern equipment is expensive. In a deregulated market the power companies don't have the money to buy it. (well, usually) And to refer to a point made a bit further up: yes, this stuff matters, because there are people who care about what the masters of the power are doing. Because i like my screen to have another color than a forced black. Thus I like power. And I want to know why people cut me off of my power.

    2. Re:Future Prevention by AKnightCowboy · · Score: 2, Interesting
      The trick is to build the power plants in the same area that the load is located in. This reduces the amount of power that must be imported or exported from any given area.

      No, the trick is to USE the power plants in the same area that the load is located in. First Energy has at least 2 nuclear power plants in Northern Ohio and one of them was shut down. Energy companies are finding it cheaper to buy electricity on the open market instead of generating their own. Yes kids, de-regulation was a horrible mistake when you do it to public utility monopolies.

      I've still never understood this. I think most systems are actually based on NT, but maybe they are migrating to 2k now. Either way, the fact that these automation systems are based on a system like windows is very strange to me. OPC (the protocol used to communicate between sensors and databases) is based on DDE (or OLE), which seems so incredibly strange to me.

      I've been developing a linux-based SCADA system. I took a look at quite a few systems, and I just didn't feel comfortable running any of them for a number of reasons. Stability and security being two major issues. Another was cost - these are being deployed in small installations, mostly for remote monitoring, which wouldn't typically have a SCADA system due to the cost. Between a mixture of existing open source software, some nice hardware, and in-house development (mostly me), the system has cost us about $20k to develop, which is less than it would cost to licence most software per site.

      Anyways, that was a bit OT, but the point is, very early on we decided that deploying on windows would be a pain. These are all remote installations, with no one on site that can service them. If something goes down, I want to be able to remotely fix it as much as possible. I just don't feel comfortable deploying a remote windows system and relying on it to stay running, not to mention the fact that people's health could be affected (water treatment). To me, windows is not the proper platform to be using for this situation.

      Maybe Microsoft will suddenly not get a contract with the power generators anymore, but that's as far as we'll ever hear of it.

      Obligatory response: Woo-hoo! Linux all the way baby!

      BTW, the EULA specifically prohibits NT and up from being used in "critical" situations where life and environmental damage are on the line. So it would be the utilities' fault, not Microsoft's.

  6. Disturbances Before Outage Itself by shoemakc · · Score: 4, Interesting


    Did anyone else notice a strobing effect in their fluorescent lighting in those 20-30 seconds before the full power outage? My understanding is that any sort of arc lamp (fluorescent, metal halide) will extinguish if the voltage sags beyond a certain point, so I doubt it could have been a voltage sag before the full blackout.

    It almost seemed as if the power frequency itself had gone unstable...say from a nominal 60Hz to like 5Hz. Then again, with the modern electronic ballasts used today, who knows how they respond to a voltage sag. Maybe they strobe. Any one have any thoughts on this?

      I live an North Eastern Ohio. I had two CRT monitors on and plugged into normal power. Both of my computers are on a UPS. I specifically remember my monitors dimming and then comming back a few times, all the awhile my UPS is going nuts, supplying extra battery power to keep the voltage up. My lights remained on, but dimmed. Then a few seconds later, maybe 10-15, the power totally went out.

      So of course I shut down my Windows machine as fast as I could, as this isn't a beastly UPS by any means, and two computers on it won't last long. I'm skilled in the art of windows keyboard shortcuts, so shuting down was no problem. As far as writing code goes, I probably save the file I'm working on once at least every 60 seconds out of habbit, ctrl-s is your friend. :) So then a few minutes later my UPS starts really going nuts, so I shutdown my linux box, by ctlr-alt-backspacing out of x, and then giving it the three finger salute. Anyway, enough rambling. :)

      Kind of odd, when the power came back, the next day my central air conditioner wasn't working after I noticed it being hotter than blazes in my computer room. The circuit breaker for that had been tripped, none of the others were.
