Abstract

This article concentrates on designing of frequency control and protection strategies for wind turbines during overfrequency emergencies. Critical overfrequency event on North-Eastern part of the UCTE network on 4th November 2006 is considered as a base case for investigation. A single bus power system model is developed to analyse the protection settings for this case and then to propose and discuss the design and recommendations for overfrequency control settings for wind turbines. The results of the investigation show that modification of the protection settings alone may not be sufficient to prevent frequency instability especially when wind power penetration is high and system inertia is low. Robust overfrequency emergency control strategies from wind turbines can therefore be required. The article provides the design for control parameter settings for different degrees of wind power penetration. The performance of the proposed frequency control with the developed settings is validated by means of simulations with the large scale pan-European model.
