doi:10.11985/2016.10.003

Abstract

Abstract:

To realize the whole low-voltage ride-through performance comprehensive evaluation of wind trubines in a wind farm, an index system of the low-voltage ride-through and dynamic reactive power support is built, and a comprehensive evaluation method of wind farms low-voltage ride-through performance based on the intimate data method is presented. The indexes on the low-voltage ride-through and the dynamic reactive power support are calculated, and the comprehensive evaluation of wind farms low-voltage ride-through performance is realized based on the intimate data method by using them. Finally, the effectiveness and feasiblity of the presented comprehensive evaluation method is verified by using the monitoring data from some wind farms operation.

Key words: Low-voltage ride-through, dynamic reactive power, intimate data method, comprehensive evaluation, wind farms
