Introduction:
Electrical power transmission involves the movement of large amounts of electrical energy from a power generating location, such as a power station or power plant, to an electrical substation where the voltage is converted and distributed to consumers or other substations. Is.
The interconnected lines that enable the movement of electrical energy are known as a "transmission network" and make up an electrical power transmission system—or as it is more commonly known. , the power grid.
Primary transmission:
At the point when this power is generated, the electrical energy is usually in the range of 11kV and even 33kV. Before being sent to the rotational focus of the transmission lines, it is stepped up to the wattage level using transformers which can be in the range of 100kV and 700kV or more, on which it can be used. . need to. Need to move. The more distance you get on the level, the more you will get
The rationale for increasing the capacitance to these voltage levels is to reduce the impedance of I2R during the influence transfer to make it more sealed. At this point as the forward voltage continues, it decreases proportionally so that the remaining constants remain constant, after reducing the I2R impedances.
This is known as essential transmission. Down in some countries, the links are used in some other way in the ground where transmission is more limited than others.
Secondary transmission:
At the point when the electric power arrives at the getting station, the voltage is normally ventured back to a voltage somewhere in the range of 33kV and 66kV. It is then sent down transmission lines from this getting station to electrical substations close "load focuses" like urban communities, towns and metropolitan regions. This interaction is called auxiliary transmission.
At the point when the electrical power arrives at the substation, it is again ventured somewhere near a stage down transformer to a voltage underneath that from which it was created — normally around 11kV. From here, the transmission stage moves to the dissemination stage, and the power is utilized to satisfy the need of essential and optional customers.
