A bus is a link between several lines. All the lines are attached and seldom have different elements like loads and generators in a power system. Each bus equated with each of four elements:
Types of Buses In Power System
- Magnitude of voltage
- The phase angle of the voltage
- An active power or true power
- Reactive power
The power system model which is used in the power flow study happens to display the interconnections between the two :
- The generating plants and substations
- Substations and transmission lines
Let us know here the different types of buses in the power system:
Load buses are also termed PQ buses. Real and reactive power is scheduled in this bus. It is not known about the voltage magnitude and phase angles. one can find it with the help of load flow solution through various techniques.
Generator buses or also called voltage-controlled buses/PV buses. It connects the generator to the generating transformer in it. The natural power generation and the voltage magnitude are defined in this type of bus. The solution for the load flow equation is done to know the voltage and reactive power level of the generator bus.
You can use a system slack as a swing bus. A slack bus has its phase and voltage defined. A power system’s first bus is known as a slack bus. It is because no analysis of load flow can be carried out without a slack bus. The slack bus can also be considered as a load flow solution reference bus. Usually, one generator bus is utilized for the slack bus.
One can examine the Power system by using these two methods:
- Mesh Current Method
- Nodal Voltage Method
That was all about the classification of different types of buses in the Power System.
