What are different types of HVDC links? - Monopolar ... midpoints of the converter stations are earthed through electrodes. The voltage of the earthed electrodes is just half the voltage of the conductor used for transmission the HVDC. The most significant advantage of the bipolar link is that if any of their links stop operating, the link is converted into Monopolar mode because of the ground ...

The Oil Drum | The Alternative Energy Matrixtheoildrum.com/node/8925The Matrix. Would you like to know what the matrix is? Okay. I'll tell you—in a bit. For each of the major energy hopefuls I have discussed on Do the Math, I characterize their various attributes in a three-tier classification: adequate (green); marginal (yellow); or insufficient (red)—possibly a showstopper.The scheme is qualitative, and I am sure some will disagree with my assignments.
