    Sombody needs to raid your skull with a baseball bat.
     
  2. Mine,must be placed on the window sill all the time, to receive the signal
    from Frankfurt a.M. (remember, Crete is at the southmost end of EU). It also
    has a weather station, complete with barometer, humidity meter and
    thermometer.
     
  3. Here, they have the base-load plants running 24/7 anyway (Crete, south
    Greece, isolated small grid), basically two-stroke diesels and small steam
    turbines, fired with mazut.), and they have the servers that control the
    grid control a regulating unit (usually a gas turbine, fired with ordinary
    diesel) controlling its output so that it picks/sheds load. There are UF
    (Under Frequency) relays on select medium-voltage (15 kV) circuit breakers
    that shed those loads, when the grid's frequency goes below a chosen point
    (automatic trip of those breakers). The best fuel economy have the
    two-stroke diesels, with 100 grams of mazut for each kWh IIRC, and then the
    steam-turbines, with 300 gram/kWh of mazut. The worst are the gas-turbines,
    with their expensive fuel, and are used only in peaks. There are no hydro in
    Crete.

    That's just DimBulb talking hard shit like a typical East County bitch.

    You think DimBulb is pathetic you should check out his neighboorhood
    East San Diego County where a bunch of wanna be skinheads and bikers
    snort meth and drive lifted trucks and think they are all hard.

    No, his mama got pregnant with him and dropped out of the 9th grade like
    every teenage bimbo does in East County.

    Years ago they bought a lot of such clocks for use in all the buildings
    at work. *After* they bought them and installed them, they found out
    that such clocks don't work very well in commercial buildings with a lot
    of steel. Such radio clocks are not all they're cracked up to be sometimes.

    Now we just use the time on the PC since they all synch with a
    time-server that in turn syncs with nist.gov.

    For the data-acquisition computers, that aren't allowed to be tied to
    our business network or internet, we put a GPS antenna on top of the
    building and tie the receiver into the DAS system.. Some folks laugh
    and ask if we're expecting the building to move much :)

    AGAIN, the retarded little **** gets it wrong.

    I do not live in East County. I am not from East County.

    Where do you want to meet, miss little soft shit?

    You talk a good one. Put your body where your pissy little **** mouth
    is. Put up or shutup, ****.

    I've got nine inches of 'typical bitch' to go up in your typically
    totally already badly reamed slut ass with, little ho.

    So you only have one or two units acting as regulating units? Then it
    certainly would be easy to keep them set the same as you adjust up/down.
    When you have many more units working 'regulation', it's often easier
    to raise/lower a non-regulating unit. That way the settings of all the
    regulating units don't have to be adjusted together constantly
    throughout the day.

    Some non-regulating units are not operated at full load all the time
    like a base-load plant. Instead they would come on line and carry an
    amount of load dictated by system operator. As system load rises, at
    first the regulators would take it but that resulted in system frequency
    dropping as the regulating units are loaded down. Then the sysop would
    call one of these non-regulating unit and ask them to pick up more load.
    When they did so, it took load away from the regulating units and
    system frequency rose back again. Since the regulating units didn't
    have to change their settings, they all gain/shed load simultaneously.
    You adjust one or two plant's output and all the regulating units can be
    left alone (well, most of the time anyway).
    We have load shedding too, but that's considered a bit drastic. In the
    days before deregulation, we too would consider heat rate and fuel costs
    (combined into simply marginal cost for any given unit). When you owned
    all different forms of generation and were responsible to a regulator to
    act prudently, you would operate your mix of plants to get the lowest
    overall cost.

    With deregulation it's up to each generating company to bid a price they
    can afford sell at and that will still win them some bids. But in times
    of high demand, price isn't set solely by what it costs the generator to
    create the power. If a generator is pretty sure his power is needed, he
    can bid a higher price and still win. In times of low demand, plants
    with high fuel costs end up bidding a price that doesn't win so they
    don't put onto the grid.

    How utterly pathetic you are.

    Whatsa matta, little ho? Is your economy going into the crapper?
    Did you run up the debt so high that the whole world around you MUST be
    to blame?

    BUAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!

    I hope you rot under an expressway overpass, with a 'will suck for
    food' sign in your hand.

    You sound like some meth head refused to pay you for your slut
    services.

    Sorry, ya little retarded bitch. I do not partake in meth.

    You sure seem to know a lot about it, however.

    GPS is the de facto standard in real network environments. It arrives
    your clock at less than 0.01 second off NIST.

    The time server cannot get you any closer than about 0.2, and that is on
    a good day.

    The MODEM based, land line hookup to NIST will get you within about 0.1
    consistently. That is because it sends and receives several
    transactions, and then compensates its sent data strings to adjust for
    your distance from the server. The online time servers do not perform
    this function, and then there are also errors introduced by the number of
    hops between you and the time server.

    Yeah the low frequency signal is blocked by a lot of things. I've heard
    you can rig up an external antenna and couple it inductively to the
    antenna in the clocks, I've always been able to find a suitable location
    to place the ones in my house though so I've never tried.

    AlwaysWrong once again proves his name. Because you haven't seen it
    must not exist. What a dim bulb you are, DimBulb.
    I don't embellish the fact that you're AlwaysWrong. Can't.
    AlwaysWrong, so wrong, always.

    What's wrong, AlwaysWrong? Am I making the poor baby cry over
    mommy's spilled hamper?

    His mommy had no live born children. SHe does have one smelly hamper
    though.

    Oh! More threats from DimBulb! Keep it up, you're gaining friends.

    And yet your claim that they are off by several minutes per month is
    accurate?

    Bullshit. You are the one that is off the mark by orders of magnitude
    here, you dippy twit.

    You are lucky that we live in a land of laws, and that I abide by them,
    asswipe.

    Otherwise, you would be vivisected, by me, and I would make sure that
    you felt the pain of it for days before you expired.

    Come back when you know what the word threat means.

    Someone declaring their opinion of "what you need" is NOT in any way,
    NOR will it ever be, in any way, a threat.

    So that's where DimBulb's mother hides her methamphetamine, the hamper.
