تطوير نظام قيادة شعاعي لمحرك تحريضي ثلاثي الطور لسلك رافعة وفق مبدأ ملاحقة الفيض المغناطيسي للدائر
Abstract
تم في ورقة البحث هذه تطوير نظام قيادة شعاعي لمحرك سلك رافعة وفق مبدأ ملاحقة فيض الدائر. تتطلب عمليات التشغيل للروافع، حالات تشغيل مختلفة بسرعات وعزوم متغيرة مع الزمن، مما يشكل حالات كهرو ديناميكية وكهرو مغناطيسية عابرة، قد تؤثر على أداء عمليات التشغيل، لذلك وبناء عليه تم بناء نظام قيادة يحقق عمليات التشغيل لمحركات السلك في الروافع يحقق: - أداء ومردود عالي - بناء نظام التحكم المطلوب وفق مبدأ التعديل النبضي العرضاني (PWM) ونظام التغذية الرئيس اخذين بعين الاعتبار الحد من تغيرات جهد حلقة التيار المستمر وتحقيق فيض اعظمي قبل اقلاع المحرك. - الحد من الجهود الزائدة التي قد تظهر على حلقة التيار المستمر، باستخدام مقطع فرملة ترانزستوري مع مقاومة تفريغ. في نهاية البحث تم استعراض النتائج والتي تدل على الأداء المتميز للنظام المقترح مع إمكانية استخدام نفس النظام لعمليات التشغيل المؤتمتة المختلفة. In this paper, the development of the drive system of the motor Wire port Crane according to the principle of the indirect field orientation. Require the operation of the port Crane operations, different operation situations of variable speed and Torque with time, which is a case dynamic electro and electro-magnetic transient, may affect the performance of operations, so therefore been building motor Wire port Crane operations system corps in winches achieve: - High performance and Efficiency. - Build the desired control system according to the principle of the Pulse Width Modulation (PWM) and the main power system, taking into account the reduction of changes DC-Link voltage and achieve maximum flux before starting the motor. - Reduction of excess Voltage that may appear on a DC-Link, using the brake Transistor with Brake resisters. At the end of the research has been reviewed and the search results that indicate the outstanding performance of the proposed system with the ability to use the same system to run automated processes different.Downloads
