Load Flow Study Basics for Power System Learners

Load flow study is the practical engineering view of how loads are supplied by available sources. It is used to check whether the network can serve demand without overloading lines, transformers, or generators.

Load flow in simple terms

A load flow calculation asks: which source supplies which load, through which path, and at what loading level? In this learning app, the simplified model focuses on MW flow and defense-scheme decisions.

Why it matters for operation

Incorrect load flow assumptions can hide overload risk. A defense scheme needs topology awareness so it does not trip the wrong feeder or accidentally worsen an islanded area.

Learning workflow

Start from a healthy network, open a line, split a bus, or constrain IBT import. Then compare final balance, overload indication, and recommended trip target.
