تحديد إدخال اتجاه الرياح ومراجعته.موقع المستشعر، صحة الإشارة، والقياس المسجل يساعد على شرح أمر التوجيه.
تقنية MARSTON
قوة الرياح تحت السيطرة.
من حركة الروتر إلى الطاقة المستخدمة.
توفر توربينات الرياح الحركة الميكانيكية، واتخاذ القرارات التحكم، وتحويل الكهرباء معا، واستكشاف كيف تتصل هذه الوظائف، وماذا يفعل كل عنصر، وما هي الواجهات التي تحدد المعدات للمشروع.
01التوجيه الكهربائي
التوجيه هو قرار التحكم.
التوجه يغير التوجه من النايل والروتر حول البرج. في ترتيب التوجه الذي يسيطر عليه الكهرباء ، يقوم المحرك بتشغيل هذا الحركة استجابة لأوامر التحكم. إنها وظيفة مختلفة عن زاوية الشريط ، والتي تغير زاوية الشريط حول محورها الخاص. المسألة الهندسية المفيدة هي كيفية عمل الحالة الحسية والحركة والتشغيل معا. اتجاه الرياح وحده ليس مواصفات التحكم الكاملة: توقيت الأمر، والظروف التي تسمح بالتحرك، والاستجابة لإشارة غير متوفرة كل شيء.
FD14-50 kW / CONFIGURATION
اتجاه التحكم الكهربائي: الدفع المباشر المغناطيسي الدائم.
على الحالة الحالية FD14-50 kW ، يحرّك محرك كهربائي آلية التوجيه. تتميز منصة 50 kW بدوار بقطر 14 m وثلاث شفرات ومولد بنقل مباشر دون فرش وبمغناطيس دائم.
داخل منصة التوربين بقدرة 50 kW
اتخاذ القرار
تحديد متى للتحرك ومتى للانتظار.يجب أن يربط وصف التحكم خطأ الاتجاه وحالة التشغيل ومعايير حركة النموذج المحدد.
التشغيل
تحويل محرك كهربائي إلى قوس قزح.مراجعة كيف يتم إيقاف الحركة وكيف يتم التحقق من موقفها وكيف يتم الوصول إلى المحرك للخدمة.
02تحويل القدرة
اتبع القوة: حدد كل واجهة.
ولديه مولد، وحدة التحكم، ومحول، أدوار مختلفة، واختيارها معًا يعني مطابقة الخصائص الكهربائية ومتطلبات التشغيل، بدلاً من مطابقة تصنيف الطاقة فقط.
المولد
يحول المولد الطاقة الميكانيكية التي يقودها الروتور إلى الكهرباء.الخصائص الكهربائية هي نقطة البداية لاختيار المعدات المنخفضة. FD14-50 kW على سبيل المثال ، يستخدم مولد الدفع المباشر المغناطيسي الدائم ؛ محطات مولدها ونتيجة AC للمحول هي حدود مواصفات منفصلة.
وحدة التحكم
يربط طبقة التحكم الإشارات المقياس مع القرارات التشغيلية. وصف مفيد للسيطرة يحدد الإدخالات والخروج والتغيرات الحكومية ومسؤوليات المعدات. ويظهر أيضًا ما هي الوظائف التي تنتمي إلى وحدة التحكم في التوربين وما هي التي تنتمي إلى معدات التحويل.
محوّل القدرة
تحويل الطاقة يعد الإنتاج الكهربائي للاتصال المقصود. تبدأ مع خصائص إدخال المولد، ثم تحديد الجهد الإنتاج المطلوب، وتردد وترتيب الاتصال. FD14-50 kW يحدد التكوين المرتبط بالشبكة 380 V خطًا إلى خطًا عند إصدار المحول ؛ تتطلب متطلبات المشروع الأخرى مجموعة منفصلة من المعدات.
MPPT
تتبع نقطة الطاقة القصوى هو نهج التحكم للبحث عن نقطة عمل مفيدة توليد الطاقة مع تغيير الظروف. في أنظمة الرياح ، يتم توصيل الشحن الكهربائي وسلوك الروتر. اسأل ما هي المعدات التي تنفذ الاستراتيجية وما هي الحدود التشغيلية المحددة للنموذج التي تنطبق؛ MPPT ليست علامة التوافق الشاملة.
03الدول العاملة
إجابة محددة، إجابة محددة.
يصف الفرامل الأجهزة، ويصف تسلسل الحماية الحدث، والرد المطلوب، والظروف المتعلقة بالعودة إلى العمل. FD14-50 kW وتستخدم التكوينات الفرامل الهيدروجينية بجانب محرك الأقراص التحكم الكهربائي، وتشكل الموضوعات أدناه إطار مراجعة للمعدات المختارة، وليس قائمة وظائف متكاملة عالمية.
01البدء والركض
انقسام حركة الروتر من توليد الكهرباء. تحديد شروط دخول الحالة التي تنتجها والقياسات المستخدمة لتأكيدها. سرعة الرياح التي بدأت في توجيه الروتر لا تضع، من تلقاء نفسها، قطع كهربائية مفيدة.
02توقف مراقبة
الوثيقة التي يتطلب الجهاز التوقف وكيف يتم تنسيق التوربين والشحن الكهربائي والفرامل.يتضمن الحالة النهائية والتوضيح الذي يؤكد الانتهاء.
03سرعة الرياح والروتر
راجع المتغير المقاس وفترة احتساب المتوسط والحد وزمن التأخير معاً. وصف الحماية غير مكتمل إذا اقتصر على قيمة سرعة الرياح دون حالة التشغيل وشروط إعادة الضبط.
04انقطاع الكهرباء
تتبع ما يحدث عندما يصبح الشبكة أو الشحن أو الإمدادات المساعدة غير متوفرة.تحديد المعدات التي لا تزال مدمجة وما هي المعدات المسؤولة عن حالة التوربين الناتجة.
05فقدان الإشارة والاتصال
ميّز بين القياس غير المتاح والقيمة الطبيعية. حدّد لكل إشارة أو اتصال مطلوب طريقة الكشف والاستجابة الناتجة والمعلومات المحفوظة لتشخيص الأعطال.
06إعادة التدوير والخدمة
تحديد الشروط التي يجب أن تكون واضحة قبل إعادة التشغيل وما إذا كان الاعتراف محليًا أو بعيدًا.تطابق الفحص والعزل والوصول إلى الخدمة وثيقة التشغيل والصيانة للنموذج المورد.
04نظام التكامل
الاتصال يحدد المعدات.
إنتاج متصل بالشبكة، والشحن المعزول ونظام الطاقة الهجينة يضع متطلبات مختلفة على الواجهة الكهربائية. ابدأ مع الهدف من الطاقة، ثم العمل مرة أخرى من خلال التحويل والسيطرة والترفين. الرسم البياني الواحد يجعل نقاط الاتصال والحدود المعدنية مرئية.
مساحة المعدات
وحدة التحكم. وحدة التحكم.
ويمكن لشركة MARSTON مناقشة توربين وحدة التحكم وتوريد المحولات بشكل منفصل، مع تنسيق توفير البرج عند الضرورة. بالنسبة للمشاريع الهجينة، تحديد المعدات الشمسية والتخزين والإشراف من طرف ثالث قبل تقييم الواجهات. في الوقت الحالي ، لا تقدم MARSTON منتجات التخزين الخاصة بها.
