All pole-slip protection relays on the market will only trip a generator after it has pole-slipped one or more times. This paper introduces a pole-slip protection algorithm, which makes use of a simplified model that still delivers accurate predictive pole-slip prediction. The algorithm uses the equal area criteria for predicting post-fault generator stability while a fault occurs. In order to successfully implement the equal area criteria, a number of parameters need to be calculated (or predicted). This paper will focus on predicting the generator and step-up transformer transient power angles, as well as the step-up transformer post-fault voltage, which are required to successfully use the equal area criteria for predicting pole-slippingenEqual area criteriaPole-slipOut-of-stepPower system stabilityPresentation
