جهاز البدء الناعم الرقمي المتقدم ABB ASTAT Plus — نظرة عامة
جهاز البدء الناعم الرقمي المتقدم ABB ASTAT Plus مصمم لأصعب تطبيقات بدء المحركات الثقيلة في الصناعة، حيث تفشل أجهزة البدء الناعم القياسية في توفير أداء ثابت بسبب ظروف الحمل المتغيرة أو الاحتكاك الساكن العالي. يستخدم ASTAT Plus خوارزمية تكيفية تقيس عزم المحرك الفعلي خلال منحدر التسارع وتضبط زاوية الإطلاق في الوقت الفعلي للحفاظ على ملف العزم المبرمج بغض النظر عن تغيرات الحمل. نطاق التيار من 17 إلى 1250 أمبير يغطي المحركات من 1 حتى 800+ كيلوواط على 690 فولت. راز الشرق الأوسط يوفر ASTAT Plus مع الضبط الكامل وخدمات الاختبار الميداني.

المميزات والفوائد
- Adaptive TorqueSoft torque-ramp algorithm continuously measures actual motor torque and adjusts thyristor firing angle in real time to maintain the programmed acceleration profile regardless of supply voltage variation, load changes, or motor temperature — essential for reliable starting of crushers and ball mills under full load.
- Kick-start function delivers a short full-voltage current pulse before the torque ramp begins, overcoming static friction in compressors and conveyors that have been standing in Saudi Arabia's desert heat, where lubricant viscosity and mechanical stiffness increase after prolonged standstill.
- Integrated comprehensive motor protection suite covering thermal model with heat balance accumulation, phase loss, phase asymmetry (>10%), PTC thermistor input, locked rotor, undercurrent (pump cavitation), and automatic restart — replacing a separate motor protection relay in the MCC and reducing panel component count.
- PROFIBUS DP and Modbus RTU fieldbus communication allows full remote monitoring and control from plant DCS, providing softstarter status, motor current, thermal state, and fault log data to SCADA systems at ARAMCO and SABIC facilities with ABB 800xA or Honeywell Experion DCS platforms.
- Current range of 17 A to 1250 A at 200–690 V covers motors from small process auxiliaries to large 800+ kW 690 V pump and compressor motors in a single product family from one manufacturer, simplifying spare parts standardisation across a facility with multiple softstarter ratings.
- Internal thyristor bypass relay connects the motor directly to supply after acceleration is complete, eliminating continuous thyristor heat dissipation during run and allowing the softstarter to handle repeated starts on large motors without thermal derating between start cycles.
- Adjustable deceleration ramp (soft-stop function) reduces pressure surge and mechanical shock during motor stopping for pump applications, complementing the starting torque ramp to provide a controlled stop that prevents water hammer in SWCC desalination and NWC water distribution pipe networks.
التطبيقات الصناعية
- Ball mill and raw mill motor starting at Saudi cement plants (Saudi Cement, Yamama Cement, Qassim Cement), where fully loaded mills require adaptive torque-controlled soft starting to prevent mechanical shock on girth gears and pinion drives rated at motor powers from 200 kW to 2+ MW.
- Large centrifugal compressor auxiliary motor starting at ARAMCO gas processing plants, where the compressor startup sequence requires controlled torque delivery to prevent shaft vibration during run-up through critical speed ranges, with PROFIBUS DP integration to the Honeywell Experion DCS startup sequencer.
- High-inertia cooling water pump motor starting at SABIC Jubail petrochemical plants, where large centrifugal pumps with significant flywheel effect require extended soft-start ramp times beyond the 30-second capability of standard electronic softstarters to avoid transformer overloading during startup.
- Conveyor drive motor starting at MODON industrial estate logistics and warehousing facilities, where fully loaded heavy conveyors require kick-start plus torque ramp to move away from standstill under load without exceeding the 250% starting current limit imposed by the site's supply transformer rating.
- Fan motor starting for large forced-draught and induced-draught fans at ARAMCO utility boiler plants and SWCC multi-effect distillation (MED) desalination plants, where the ASTAT Plus deceleration ramp prevents reverse airflow surge when the fan decelerates and the damper control sequence is too slow to close before backflow begins.
- Crusher motor starting at quarrying and aggregate processing operations supplying NEOM and ROSHN construction projects, where primary crushers with high breakaway torque requirements and variable feed conditions demand adaptive torque control to avoid repeated nuisance trips on standard softstarters.
- Emergency generator set starting assist for large EMERSON and MAN diesel generators at SABIC and ARAMCO facilities, where the ASTAT Plus installed in the motor starter of generator cooling water pumps provides soft-starting to reduce mechanical stress on generator-direct-coupled pump impellers during every generator start cycle.
