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 it’s 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).تقییم 1-المرحلة، 3-المرحلة والبرق العیوب فی مزارع الریاح باستخدام تدارس خاصة-RVمنذ تطویر طاقة الریاح ترکیب النباتات تنمو، المشاکل المتعلقة شبکة الاتصال، تصبح الاستقرار والجهد آثار أکثر أهمیة. من ناحیة أخرى، مزارع الریاح غالبا ما تکون مفتوحة إلى البرق بسبب طولهم طویلة ومظهر معین. فی هذه النمذجة والمحاکاة ورقة من العیوب 1-المرحلة، 3-مرحلة والبرق فی مزرعة الریاح التی تتکون من 40 توربینات الریاح وأخطاء تأثیر على مزرعة الریاح والشبکة ویجری التحقیق فی البیئة تدارس خاصة-RV. فی هذا المجال من الضروری تطویر نماذج دقیقة من محطة لطاقة الریاح من أجل تقییم آثار هذه المحطات على السلوک الدینامیکی للنظام الطاقة. هذه النماذج یمکن استخدامها فی تصمیم نظم جدیدة للحمایة، خوارزمیات جدیدة للحمایة، واستراتیجیات جدیدة لتحسین محطات الطاقة الاستغلال. یتم توصیل کل وحدة الریاح فی المزرعة إلى وحدات کاملة متصلة بالشبکة باستخدام مولد الحث تغذیة مضاعفة (DFIG). 评价中的单相,三相和雷击事故风电场使用EMTP-RV军刀阿拉比z,萨希卜阿卜杜勒·汗抽象由于风力发电厂安装的发展的不断增长,对网络连接相关的问题,稳定性和电压的影响变得更加重要。另一方面,风电场,因为它们的长的高度和特定外形的常开雷击。本文建模的单相,3相和雷击事故模拟一个风电场包括风电场40的风力涡轮机和故障影响,并在网络中的EMTP-RV环境进行了研究。在这一领域有必要开发一个精确的建模了风力发电厂的,以便评估这些发电厂对电力系统的动力学行为的影响。这些模型可以在设计新的保护系统,保护新算法,并为电厂利用改进的新战略中。场中的每个风力单元被连接到连接到使用双馈感应发电机(DFIG)网络的整体单元。
