Why electricity generated at exactly 11kv from the generating station before it is even stepped up with a transformer?
In particular power production systems, such as medium-voltage power plants or locations where the distribution voltage currently operates at 11 kilovolts, electricity is often produced at a voltage rating of 11 kV (kilovolts).
This standard voltage level is measured in kilovolts. Nevertheless, it is essential to keep in consideration that the level of voltage at which energy is produced might differ from one power plant to another depending on the architecture of the power plant in concerned.
Deciding to use a generating voltage of 11 kV may be impacted by a number of factors, including the following:
1). Transmission & Distribution System
2). Efficiency of Transmission
3). Safety & Precautionary Measures
1). Transmission & Distribution System
The voltage level of 11 kV is typically utilised for medium-voltage distribution systems, which are part of the transmission and distribution system.
By generating energy at that voltage, it is possible to simplify the design of the infrastructure since it corresponds with the succeeding phases in the process of transmitting and distributing power.
2). Efficiency of Transmission
Transmission Efficiency possessing voltage levels that are higher makes it possible to transmit power over greater distances in a more effective manner.
During long-distance power transmission, transmission losses may be reduced by producing energy at 11 kilovolts and then utilising transformers to boost the voltage to a higher level.
3). Safety & Precautionary Measures
Different types of machinery and systems that are used in the process of power production and gearbox each have their own unique voltage ratings.
It’s possible that the electrical equipment in the power station would be compatible with producing energy at 11 kV, making this option an appropriate one to take into consideration.
How is electricity generated at exactly 11kv from the generating station?
With respect to 11 kV of electricity is generated from the generating station, it is essential to explain that the level of voltage at the point of generation relies on the particular design of the power plant.
This is because the value of voltage level at the point of generation is exactly identical based on design of generation.
The transformation of mechanical energy into electrical energy is accomplished in power plants by using a variety of generators, such as synchronous generators and induction generators.
The design of the generator, the rotational speed of the shaft, the intensity of the magnetic field, and the winding arrangement are the factors that decide the output voltage of the device.
To ensure that the generator produces energy at the specified voltage level, for example 11 kilovolts, these parameters may be modified throughout the design and building phases of the project.
It is important to keep in consideration, however, that the voltage level that is directly generated by the generator in certain power plants could not always equal 11 kV.
Before being sent to the distribution grid (or) further changed so that it may be distributed to customers, the output voltage of the generator is often reduced and then raised by means of transformers.
This occurs in the majority of conditions. Increasing the voltage is done in order to accomplish the purposes of lowering transmission losses and improving the efficiency of the delivery of power over long distances.
