ABB REU615 HBUAEAADANB6ANN1XG
Core positioning: Voltage regulating protection and measurement device, suitable for substations and distribution systems that require automatic or manual adjustment of transformer on load voltage regulation.
In terms of protection and control functions, standard configuration B supports manual or automatic voltage regulation with load tap changer transformers, which can be used for load side voltage regulation in small substations with only one transformer. At the same time, it has complete voltage protection functions, including bus undervoltage and overvoltage monitoring, load shedding and disconnection, and load recovery and reconnection. In terms of frequency protection, it supports over frequency and low frequency protection for generators and motors. In generator and motor protection applications, auxiliary protection can also be provided by detecting frequency and voltage offsets. The integrated synchronization function ensures reliable connection between the equipment and the power grid. In distributed generation and distribution networks, it can serve as a disconnection protection (LOM) for individual power generation units. Optional arc protection and high-speed exit function, but cannot coexist with automatic voltage regulation function.
In terms of measurement and monitoring, real-time monitoring of operating parameters such as bus voltage and frequency, providing high-precision voltage and frequency measurements, and supporting fault recording. Equipped with a large-sized LCD panel with editable single line diagram display, supporting local operations and remote HMI access based on web browsers.
In terms of communication, it supports IEC 61850 version 1/2, including HSR, PRP redundancy, and GOOSE messages, and is compatible with IEC 61850-9-2 process bus. Simultaneously supporting Modbus, DNP3, and IEC 60870-5-103 natively. Supports IEEE 1588 v2 high-precision timing protocol.
In terms of hardware, it adopts a pluggable design that supports quick installation and testing. The working temperature ranges from -25 ℃ to+70 ℃, with a protection level of IP20. It is equipped with a graphical LCD panel that supports local parameter viewing and setting modification.
