ABB SUE3000 1VCF750090R0804 High-Speed Bus Transfer Device HSTS for Power Plant Auxiliary Power System

Description

Product Introduction

Auxiliary power failure in thermal power, combined-cycle and petrochemical plants will lead to unit shutdown and huge economic losses. Ordinary ATS automatic transfer devices have a long switching time, which is easy to cause motor stall and equipment damage. The ABB SUE3000 (1VCF750090R0804) is a high-speed bus transfer controller (HSTS/HSTD) developed by ABB, specially used for the fast switching of medium-voltage plant power supply. It calculates the voltage vector difference between working power supply and standby power supply in real time, captures the optimal closing moment, and completes the power switching within about 30ms. It avoids the inrush current impact of asynchronous closing, ensures the continuous power supply of important motors and loads, and is the core protection control unit for critical power supply occasions. It is widely used in the transformation and maintenance of the auxiliary power system of power plants, and is a mature spare part for the existing SUE3000 fast cutover system.

3. Key Features & Benefits

Ultra-fast switching speed, typical transfer time ≤30ms: Match ABB high-speed vacuum circuit breaker VM1-T, complete switching within 1.5 power frequency cycles -> Avoid large motor stall, maintain continuous operation of important auxiliary equipment, prevent unit trip.

Multiple transfer modes configurable: Include residual voltage transfer, synchronous closing transfer, sequential transfer and manual transfer, adapt to various fault scenarios of busbar loss of voltage -> Flexible adaption to different plant wiring schemes (2-incoming 1-bus / 2-incoming 2-section bus).

Built-in fault recording and oscillograph function: Record voltage waveform, switching action sequence and fault event time stamp for each transfer process -> Convenient for post-fault analysis, protection verification and audit.

Rich communication protocols: Support IEC61850, Modbus RTU/TCP, IEC 60870-5-103, SPABUS, LON -> Seamlessly connect with DCS, SCADA and relay protection system to upload status, alarm and action information.

FUPLA functional block programming: Visualized logic programming, customized interlock and protection logic according to site requirements -> Adapt to special interlock requirements of different power station projects.

Integrated self-monitoring and loop supervision: Monitor the circuit breaker coil, power supply and internal hardware in real time, alarm for abnormality in advance -> Reduce hidden danger of failure refusal.

6. FAQ

Q: What is ABB SUE3000 1VCF750090R0804 used for? A: SUE3000 is ABB high-speed bus transfer controller, mainly used for plant auxiliary power system. It automatically switches from failed working power supply to standby power supply in ultra-short time to keep important motors running continuously. Q: What is the difference between SUE3000 and ordinary ATS? A: Common ATS transfer time is 200~300ms or longer, motors will stall easily. SUE3000 high-speed transfer can finish switching within 30ms, it can realize synchronous closing and restrain impact inrush current, specially for power plant critical auxiliary loads. Q: Does SUE3000 need to work with special circuit breakers? A: To reach 30ms transfer performance, it needs to match ABB VM1-T high-speed magnetic vacuum circuit breaker. It can also work with other breakers, but the switching time will increase accordingly. Q: Is SUE3000 still in production? A: SUE3000 is a mature legacy fast transfer device. The available stock are fully tested spare units for existing power station auxiliary power system renovation and maintenance.
