ريلاي ABB REB615 لحماية العوارض والمغذيات IED — نظرة عامة
ريلاي ABB REB615 هو جهاز إلكتروني ذكي IED مدمج لحماية المغذيات المتعددة من سلسلة ABB Relion 615، يوفر حماية التيار الزائد والعطل الأرضي للعوارض الكهربائية ومغذيات التوزيع LV وMV في هيكل 1U واحد مقاس 19 بوصة. يحل REB615 محل أربعة ريلايات منفردة الوظيفة بجهاز واحد، مما يُقلل مساحة اللوحة وتعقيد التوصيل بشكل كبير. يتوافق الريلاي بشكل أصلي مع IEC 61850 ويدعم رسائل GOOSE وتكامل SAS مع MicroSCADA. راز الشرق الأوسط يوفر ويُشغّل ريلايات REB615 لألواح حماية محطات التوزيع الثانوية في المملكة.

المميزات والفوائد
- Four independent protection zones in a single 1U 19-inch IED replace four individual single-function overcurrent relays, reducing secondary substation protection panel height, CT secondary circuit wiring, and relay test point connections by up to 75% — a significant cost saving on new secondary substation panel builds.
- Native IEC 61850 compliance (Edition 2) with GOOSE messaging for inter-IED communication and MMS for SAS integration enables the REB615 to participate in a full digital substation architecture — meeting Saudi Electricity Company (SEC) Smart Grid programme requirements for new 13.8 kV secondary substations.
- Independent IDMT time-current characteristic selection per zone (IEC Standard Inverse, Very Inverse, Extremely Inverse, and Definite Time options) allows precise grading with upstream 33 kV or 13.8 kV protection relays and downstream LV fuses, achieving full IEC 60909 selectivity at every distribution level.
- Directional overcurrent protection option (67P/67N) enables use in ring-fed distribution networks, where fault direction discrimination is required to identify which feeder segment contains the fault — a requirement for ring main unit (RMU) feeder protection in SEC urban distribution networks.
- Backward-compatible Modbus RTU and IEC 60870-5-103 communication protocols allow integration with legacy SCADA systems at existing Saudi Electricity Company, ARAMCO, and SABIC facilities that predate IEC 61850 migration, enabling REB615 installation in existing SCADA-integrated substations without SCADA system upgrade.
- Integrated event recorder and fault record storage with millisecond time-stamped event log provides the sequence-of-events data needed for post-fault analysis and SEC incident reporting — replacing the need for a separate digital fault recorder in secondary distribution substations.
- ABB SAB relay test tool compatibility and IEC 61850 COMTRADE format fault record export enables secondary injection testing and protection coordination verification using standard test equipment without requiring an ABB proprietary test interface — reducing substation commissioning test equipment cost.
التطبيقات الصناعية
- New SEC-approved 13.8 kV secondary substation protection panels under the Saudi Electricity Company Smart Grid expansion programme, where IEC 61850 native protection IEDs are specified for all new substations feeding residential developments, NEOM utility nodes, and commercial district distribution networks.
- Industrial MCC incomer and feeder protection at MODON and SIDF industrial estates, where the REB615 four-zone architecture provides both main incomer and up to three feeder protection functions in a single panel-mounted IED — replacing multiple single-function relays in the MCC protection panel.
- MARAFIQ and SWCC secondary substation protection at industrial utility facilities in Jubail Industrial City, where IEC 61850 GOOSE communication between protection IEDs enables automatic bus coupler operation following incomer protection trip — maintaining supply to healthy bus sections.
- Ring main unit feeder protection at SEC urban distribution network RMUs, where the REB615 directional overcurrent option (67P/67N) enables the protection system to identify which ring segment contains the fault and isolate it, automatically restoring supply to healthy ring segments within the SAIDI improvement targets set by ECRA.
- ARAMCO compound distribution substation protection at residential, administrative, and industrial compound substations, where ABB Relion IEDs are specified for IEC 61850 integration with the ARAMCO Distribution Automation System (DAS) central control system in Dhahran.
- Secondary protection IED retrofit for aging electromechanical relay protection panels at existing SEC substations under the SCADA Upgrade Programme, where the REB615 IEC 61850 interface enables integration with the new MicroSCADA-based substation control system while the IED's physical current transformer connections remain unchanged.
- Protection relay for NEOM utility infrastructure secondary substations, where the project's commitment to a fully digitalised power system requires IEC 61850 Edition 2 GOOSE and Sampled Values capability from all protection IEDs — a capability the REB615 provides natively with no additional hardware.
