Load Flow Analysis by AllumiaX
What is Load flow?
Load flow, also known as Power Flow Analysis, is an essential method to examine the problems occurring in the power systems network or grid.
Load flow Analysis is performed to determine the state of the equipment present in the network in order to ensure their operation within the specified limits. This study solves the steady operation state with node voltages and branch power flow in the power system.
We just launched our Power Systems Engineering Vlog series and in this series, we are going to talk about all sorts of various power system engineering studies and commentary. We will overview the different blogs written by AllumiaX. It’s fun, it’s lively, it’s a video blog essentially. Signup Now and get a 30-Days FREE trial.
Analysis of Power flow Study:
There are four quantities in a system node that are classified as the Voltage Magnitude, Phase Angle, Real and Reactive Power. While defining the system nodes, we consider three types of buses.
The buses and quantities are correlated with each other. The buses are named as Load bus, Generator bus and Slack bus.
The buses with no generators are load bus (P-Q bus). Here, V and θ are unknown whereas the real and reactive power are known.
In Generator bus (P-V bus), Q and θ are unknown. At this bus the magnitude of the voltage is kept constant and the real power is provided by the prime mover of the generator.
Slack bus is also known as reference bus. The voltage is fixed in both magnitude and phase where P and Q are unknown.
How to calculate Load flow?
To calculate load flow, there are 3 techniques out of which two are the most common.
- Gauss Seidel Method
- Newton Raphson Method
- Fast Decoupled Method
