“How can we make a sturdy conductive cable?”

 

Transmission lines need large amounts of cables to travel long distances. However, this means that they will also need to be sturdy and rigid while being lightweight. This can be solved by placing a steel holder wire surrounded by aluminum wires in a setup known as ACSR Cables (Aluminium-conductor steel-reinforced cable). ACR cables are widely utilized in India, forming the bulk of power transmission cables.

“How can we use synchronous motors to stabilize the grid?”

 

Synchronous Motors are great for precision control applications. But their usage can be applied to grid stabilizations. Since voltage in a grid can fluctuate, by running synchronous motors at no-load speeds we can effectively have a load that adds inertia to the system, therefore mellowing out the voltage fluctuation. These devices are known as a Synchronous Compensators and are a vital part of the modern grid.

“What connects all of India’s electricity sector together?”

 

India is one of the largest countries in the world and is about to become the most populous as well. And it must find a way to meet the electricity needs of its citizens. This is done through a National Power Grid, which connects 5 regional grids through high voltage electricity. This allows for power trading and stabilization when necessary.

“How can we hook up two asynchronous power connections?”

 

Different power grids might operate at different frequencies. And they might also cover different geographic regions that offer different but useful resources. They can be hooked up together at an HVDC substation using something called a Back-to-back Connection.
