چکیده

An investigation of ferroresonance in a 230-kV transformer is undertaken. Correct modelling of the iron-core losses and the direct magnetic coupling between phases are shown to be important in duplicating field observations. A brute-force time-domain method and an analytical method for displaying margins to ferroresonance on a parameter plane are compared. Following proposed bus modifications, it is shown that loading resistors may now be made switchable.

Field Testing, Modeling and Analysis of Ferroresonance in a 230 Kv Power System

Catastrophic equipment failures continue to occur today due to ferroresonance even though this phenomenon has been extensively studied over the past ninety years. This thesis is concerned with the task of defining where ferroresonance problems can exist in a 230 kV power system and determining methods for displaying safety margins between nonferroresonant and ferroresonant operating regions. Pr...

Impacts of New Suggested Ferroresonance Limiter on the Stability Domain of Ferroresonance Modes in Power Transformers Considering Metal Oxide Surge Arrester Effect

this work studies the effect of neutral earth resistance on the controlling ferroresonance oscillation in the power transformer including MOV surge arrester. A simple case of ferroresonance circuit in a three phase transformer is used to show this phenomenon and the three-phase transformer core structures including nonlinear core losses are discussed. The effect of MOV surge arrester and neutra...
