First off, I found an error on the display screen. Did anyone else see this??? Look at the generator output section. Notice the generator voltage. 24000 KV? That would be 24 megavolts or 24,000,000 volts. Correct units should be ‘V’ as in 24 kilovolts or 24,000 volts. So you are in the middle of an […]Read more "2/13/18 Display Error and Flashing Annunciators"
So you think you have the plant mastered? Well time for some events. Events are abnormal conditions that sometimes happen in real plants. The events in my simulation aren’t too severe. With practice, you will be able to handle anything the program throws at you! There are 9 events, or 10 counting normal operation. There […]Read more "9/8/17 – Events"
There are a number of actions that need to take place as you start up the plant and move to producing electricity. If you don’t perform these operations, you get dinged with a Procedure Violation! Switch from Start-Up Transformer to Auxiliary Transformer After the Generator is online and before Generator load is > 5%, switch […]Read more "9/7/17 – Procedure Violations"
My simulator does not model extreme events that real power plants are designed to handle. When the simulator nears 1 of 7 conditions, a ‘Sim Halted’ page is displayed and the simulation stops. Current parameters as well as the ‘halting parameter’ are printed out for reference. Primary Pressure > 2600 psig Pressurizer Level < 11% […]Read more "8/29/17 – Halting The Simulation"
Back to writing the software. Got the plant up to 100% power – actually the reactor was at 101% power. When everything was stable, I decided to trip one of the main feed pumps to see how the plant behaved. Instantly, I got a Steam/Feed Mismatch alarm. With dropping Steam Generator levels, I kicked on […]Read more "8/7/17 – Plant at 100% Power"
I got 22 of the 32 annunciators converted to the new relay board. With this board, I was driving the annunciator lights (6.3 v screw base bulbs) with 5 volts. I turned on all 22 lights at once and noticed a voltage drop on the Power Distribution Board. Looks like I was starting to overload […]Read more "8/7/17 – Another Hardware Change"
I finally got all of the lights switched on the Annunciator Panel. Mounted the new Annunciator Relay Board on the back. Remaining work is to wire-in the trigger/light wires to the board and dress up all of the wiring.Read more "7/31/17 – Annunciator Relay Mod"
I finished converting the first row of annunciator lights. Due to the ‘Christmas tree’ lights burning out, switching to 6.3 v bulbs and sockets. I’m keeping the trigger and light wires together to they can use any of the relay blocks on the new relay board. Only 24 more to go! It’s taking a while […]Read more "7/24/17 – Convert the Annunciator Lights"
Got the new Annunciator Relay Board populated and tested. Now starting to remove the old lights and install the light bulb sockets. After the sockets are installed, run trigger and light bulb wires to the new board. Hopefully will be done by this weekend. That should be it for hardware mods!Read more "7/17/17 Annunciator Relay Board"
I got the 12 volt bulbs. Did a side-by-side comparison. You can see the 6 volt bulbs (running with 5 volts) look the same as the 12 v bulbs. Will stay with the 6 volt bulbs since the back of the Annunciator box is already wired for 5 volts. The bulb on the right is […]Read more "7/13/17 6.3 vs 12 Volt Bulbs"
