Before we discuss about Power Distribution Planning, we might as well go back to learn, review, and refresh the basic concepts of power distribution.
What is a power distribution?
Power distribution is the final stage of the delivery of power from its generation to the end-users. This delivery process consists of several stages which basically consist of:
- Generation
- Transmission
- Distribution
The process of power delivery starts at the generating facility, the first stage, where electricity is being generated. There are a many ways to generate electricity and mostly it is by rotating a turbine which is coupled to a generator rotor through the use of steam, water, and air. Once the power is generated, it goes to a transformer where the voltage is transformed up to transmission voltage to travel across high voltage transmission lines. The transmission lines generally connects to the grid then to substations which step down the voltage to distribution level. These substations are generally owned by the electric utilities which will be responsible in distributing the electricity to the end-users, mostly through another voltage transformation for safe customer use.
Simple enough? Not quite as this simple concept holds all schools of electrical engineering and all our discussions will revolve on this simple foundation.
