Evaluation of 1-phase, 3-phase and Lightning Faults on Wind Farms using EMTP-RV

Abstract

Since development of wind power plants installation is growing, problems related to network connecting, stability and voltage effects become more important. On the other hand, wind farms are often open to lightning because of their long height and specific appearance. In this paper modeling and simulation of 1-phase, 3-phase and lightning faults in a wind farm consisting of 40 wind turbines and faults impact on wind farm and the network is investigated in EMTP-RV environment. In this field itâs necessary to develop a precise modeling out of wind power plant in order to evaluate the effects of these power plants on dynamical behavior of the power system. These models can be used in designing new protection systems, new protection algorithms, and new strategies for power plants exploitation improvement. Each wind unit in the farm is connected to the whole units connected to the network using a doubly fed induction generator (DFIG).تÙÛÛÙ 1-اÙÙرحÙØ©Ø 3-اÙÙرحÙØ© ÙاÙبر٠اÙعÛÙب ÙÛ Ùزارع اÙرÛاح باستخدا٠تدارس خاصة-RVÙÙØ° تطÙÛر طاÙØ© اÙرÛاح ترکÛب اÙÙباتات تÙÙÙØ Ø§ÙÙشاک٠اÙÙتعÙÙØ© شبکة اÙاتصاÙØ ØªØµØ¨Ø­ اÙاستÙرار ÙاÙجÙد آثار أکثر Ø£ÙÙÛØ©.
