HVDC Hokkaido–Honshu
In Japan, a land so grand,
Two islands, Hokkaidō and Honshū, hand in hand.
A link was built, so strong and true,
To connect their power grids, it's something new.
With a length of one hundred ninety-three,
This HVDC line connects, you see.
Hokkaidō's power, to Honshū it sends,
A connection that never ends.
Static inverters, they make it work,
Converting power, a clever quirk.
Thyristor converters, oh so smart,
They keep the electricity flowing, playing their part.
Overhead lines and cables deep,
They connect the terminals, a secret to keep.
One hundred forty-nine kilometers in the air,
And forty-four kilometers under the sea, if you dare.
In 2019, a new system was born,
With voltage-source converters, power reborn.
Three hundred megawatts, a mighty force,
The link between the islands, a powerful source.
So let's celebrate this link so grand,
Connecting Hokkaidō and Honshū, hand in hand.
A marvel of engineering, for all to see,
The Hokkaidō-Honshū Link, a true beauty.
