| Power generation, transmission, and distribution engineering riddles: |
| Overcurrent sensing is intuitively simple. But what would you do to determine which way AC-fault-current is flowing in a line? |
| With a total blackout, individual powerplants become fragmented into islands. What would you do to automate tie-closure for reuniting these fragmented islands. And how would you manage spinning-reserve while adding loads? What must we avoid? |
| When using series-capacitors (to minimize inductive line drop) how does one mitigate transient sub-synchronous resonance? |
| How does one compensate the feedback loop for a static-VAR-compensator? |
| Why do some generator designs call-out hydrogen for blanket-gas? |
| How does one operate the synchronous condenser? What does it do? |
| Why is loss of excitation potentially catastrophic for the turbogenerator? How do we detect this? How do we minimize the resulting disturbance? |
| Why is inrush-surge made worse by already-energized parallel transformer primaries? How do line-filters effect the situation? How can inrush-surge be eliminated or minimized? |
| I seem to be getting the message that there are no challenges in Alaska. So I've embarked upon a research quest of my own. The following is an incomplete list of questions I ponder. I add links to answer-pages as I uncover revealing information. |
| What is coordination in voltage-flashover terms? |
| How are fuses, sectionalizers, and reclosers coordinated? |
