Instability and voltage collapse problem are two common problems in modern distribution systems. The most important task for distribution system is to efficiently simulate the system, identify the sensitive nodes and address the uncertainty using a suitable mathematical model. The paper presents a Fuzzy modeled solution for three phase Radial Power Distribution System (RDS) and simulates Voltage Stability Index (SI) for all the nodes so that the conditions of voltage collapse can be known real time. Uncertainties in Load & Line parameters are modeled as Fuzzy functions, hence results obtained incorporates the uncertainty, can be used as an early warning and is a useful input for planning purposes.
