Could you please explain it? I am guessing "the two games happening immediately one after another. Correct?"UltrafastPED said:
An HVDC back to back system is a type of power transmission system that converts alternating current (AC) to direct current (DC) and then back to AC. It is used to transfer high voltage power between two AC grids that are not synchronized.
The system uses power electronic devices, such as converters and inverters, to convert the AC power to DC and back again. The DC power is transmitted through a high voltage DC line and then converted back to AC at the receiving end. This allows for power to be transferred between grids with different frequencies or phases.
One of the main advantages of this system is its ability to transfer power between grids with different frequencies or phases. It also has a lower transmission loss compared to traditional AC systems, making it more efficient. HVDC back to back systems also have a smaller footprint and can be built in areas with limited space.
One of the main disadvantages is the high initial cost of building the system. It also requires sophisticated control and protection systems, which can be expensive and complex to maintain. In addition, the DC line used in the system can be vulnerable to lightning strikes and other disturbances, which can cause disruptions in power transmission.
HVDC back to back systems are commonly used to connect two power grids with different frequencies or phases, such as in international power transmission. They are also used in renewable energy projects, where the power generated from sources like wind or solar needs to be converted to a different frequency or phase to be integrated into the existing grid.
