In this lesson we'll learn how to synchronize a generator to the gird using synchronization lamps and a synchroscope and examine the electrical and mechanical transients that occur at the time of synchronization. Additionally, we'll examine how a generator, once synchronized to the grid, exports real and reactive power. (Part 1 of 2)

A little nerdy historical comment: Back in the day, we were converting our transmission substations to micro-processer controls. We set up a synch-scope displays on computer screens and tried to remove the analog synch scopes. We figured it's all software so analog goes bye-bye. But ... our operators had us reinstall the analog scopes. Why? In emergencies a "black" start may be required to where personal would have to manually bring up the grid without computers. They had to able to see when differing parts of the grid need reconnection and synched. Lesson on how there are multiple stakeholders with differing priorities even if we think tech solves everything. Besides ... what's wrong with a little analog? Aint the real world analog and we pretend we can digitize everything? As a power guy, I think you do a real good job with your explanations. It's useful and needed. Good job.

True dat. As easy and tempting as it is for people to make fun of old technology, it does have its place! For example analog needle meters are far easier to detect rapid changes or differences between readings than a digital display of numerical data only. When you're scanning a collection of needle meters its easy to see the one needle out of place, oscillating, or the one that suddenly spikes or drops. If you used all modern digital numerical data that important observation would be lost in a sea of numbers.

Hello Jim, this is very informative. Could you please uplaod part two of this two part series. Thank you

@bigbadtech 6 месяцев назад

Editing it as we speak! Stay in touch. I hope to release it later this week.

@Enigma758 6 месяцев назад

Thanks. When synchronized, what keeps the power from the grid from overloading the generator since it provides such massive power?

@bigbadtech 6 месяцев назад

I'll explain more in part 2 which I'm editing as we speak. Long story short if there's no differential at the time of synchronization there's no exchange of power, mechanically or electrically, in or out. In part 2 I actually purposely bring a generator onto the grid 180 out of phase ... super bad things happen!

@Enigma758 6 месяцев назад

@@bigbadtech Thanks, I look forward to your next video. Another question I have is what keeps the two lock stepped in place. I think the physics may do that and no continued external phase compensation, etc. is required. But I may be wrong about that.

With the three lamp method(s), there is another widely used method. I believe it used to be called the Siemens & Halske method, or 2 bright 1 dark method. One lamp is connected in the same manner as the all dark method (A phase to A phase). The two other lamps are interconnected between the remaining two phases, across the paralleling contactor. i.e. one lamp is connected B phase incoming to C phase grid, the other is connected C phase incoming to B phase grid. This method can be used for synchronisation where a synchroscope is not available. The lamps should be arranged in a triangular shape, so that they dance around in circles to show the same thing as a synchroscope.

True dat! I have a picture somewhere of this setup from an old abandoned hydropower facility.
