REU615 电压保护测控装置, 在公用和工业配电系统（包括具有分布式发电的电网）中可以很好地满足电压和频率的保护。REU615 IEC电压保护测控装置也是电压调节的理想装置。
RREU615 电压保护测控装置有两种标准配置方案可选：标准配置 A 和标准配置 B。
- 标准配置 A 可应用于母线低压和过压监视、甩负荷（切断）及负荷恢复（ 重接）等应用。该配置也可用于发电机和其他交流设备（例如电容器组）的过频和低频保护。在发电机及电动机保护应用中，REU615 还可通过检测频率和电压的偏移来提供辅助保护。集成的检同期功能确保了设备与电网的可靠连接。在具有分布式发电的配电网中，REU615 还可作为单个发电单元的解列保护（LOM－Loss-of-mains）。
- 标准配置 B 可应用于具有电动有载调压开关变压器的电压手动或自动调节。在只有一个变压器的小型变电站中，REU615 可用于负荷侧电压调节。标准配置 B 也具有保护功能。
REU615 IEC电压保护测控装置是 ABB Relion® 产品家族中的 615 产品系列的成员。

REU615E_D
The REU615 voltage protection measurement and control device is well suited for voltage and frequency protection in public and industrial distribution systems, including grids with distributed generation. The REU615 IEC voltage protection measure and control unit is also ideal for voltage regulation.
The RREU615 voltage protection measurement and control device is available in two standard configurations: Standard A and Standard B.
Standard Configuration A can be used in applications such as bus low and overvoltage monitoring, load rejection (cut-off) and load recovery (reconnection). This configuration can also be used for over – and low-frequency protection of generators and other AC equipment, such as capacitor banks. In generator and motor protection applications, the REU615 also provides auxiliary protection by detecting frequency and voltage offsets. The integrated check synchronization function ensures a reliable connection between the equipment and the grid. In distribution networks with distributed generation, the REU615 also acts as a lem-loss-of-mains protection for a single generation unit.
Standard Configuration B can be used for manual or automatic voltage regulation with electric on-load regulator switch transformers. In small substations with only one transformer, the REU615 can be used for load side voltage regulation. Standard configuration B also has protection.
The REU615 IEC Voltage Protection measurement and Control unit is a member of the 615 product family in ABB’s Relion® product family.
