There has been some confusion among my peers regarding the following circumstances. Often during the design of a ground grid, an engineer will specify that overhead shield wires from incoming lines must be tied into the ground grid prior to energization for a safe system. I've been told by a few...
I could rephrase the same question, why does the frequency decrease when load exceeds generation?
I know these are fundamental operating characteristics of a power system network but I'm not sure I can mathematically prove it. My best guess is that everything dissipates more power when the...
I've read through a lot of old threads on this, and I admit I still do not fully understand. I just want to double check this.
S = P + jQ. The sign of Q is completely dependent on whether the load is leading or lagging, AND which convention you take the sign of P to be in.
For example. For...
I have a question in regards to a project I'm involved with. Specifically, this is a Wind Farm generation facility although the answer to my questions does not necessarily have to be specific to wind farms. The turbines at this particular facility are DFIG machines that are capable of...
