3 Different Types of Electrical Buses in Power Systems

The Electrical Buses are the metallic strips/metallic bars which are designed inside any power system. Such buses serve as a junction point where the power is gathered for distribution purposes. In this article, you will learn the 3 different types of Electrical Buses in any power system.

Some Basics

While designing any power plant, there are four major parameters to which we are dealing. The list of these parameters is:

  1. Real Power
  2. Reactive Power
  3. Voltage
  4. Phase

While designing buses two of four parameters are known to us, and we have to develop different techniques for solving these problems.

Slack Bus

The slack bus is also known as Reference bus. The word ‘Swing bus’ is usually referred to as the slack bus.

In slack bus, the voltage and phase angle are known to as and we have to use some numerical methods for finding other two parameters (P,Q)

Generator Bus

It is also known as PV Bus. As the name itself explains, the known parameters are a real power and voltage profiles are given and we have to develop the methodology using Numerical Analysis for achieving Phase and Q.

Load Bus

It is also known as PQ bus. Here both parameters of Power (Real one and the reactive) are known to us and other two are unknown.
