ABB UNITROL1000 3BHE014557R6104 Product Introduction and Technical Parameters

Electrical Technical Parameters

Input Parameters: The module supports dual power supply input modes, including 24V DC industrial power supply and 110V/220V DC power supply commonly used in power cabinets. It is equipped with multi-channel analog signal input interfaces, which can collect generator terminal voltage, stator current, reactive power and other operating signals in real time, with high signal acquisition accuracy and strong anti-interference ability. The input signal sampling range covers the conventional operating parameter range of medium and small synchronous power generation equipment.

Output Parameters: It outputs stable excitation control signals and adjustable regulation signals to drive the excitation execution unit. It supports continuous and smooth adjustment of excitation current and voltage, with fast response speed to meet the dynamic regulation requirements of generator sudden load increase and decrease. The output control accuracy reaches ±0.5% of rated value, ensuring the stable operation of generator terminal voltage and reactive power output.

Environmental Adaptation Parameters

Environmental Adaptability: It has good dust-proof, moisture-proof and electromagnetic interference resistance performance, compliant with IEC 61000 electromagnetic compatibility standards. It can adapt to complex industrial environments such as power plants, industrial workshops and marine power systems, and resist vibration and electrical interference generated by on-site power equipment.

Core Product Characteristics

This product adopts a modular integrated design, with compact structure and strong compatibility. It features full digital control logic, abandoning traditional analog control circuits, which effectively improves control precision and system stability. It has built-in complete signal acquisition, data calculation, logic judgment and fault diagnosis functions, with high integration and fewer external matching components. The module supports real-time data monitoring and status feedback, with LED status indicators and fault code display functions, which can intuitively feed back equipment operating status and fault information. In addition, it supports multi-protocol communication docking, realizing seamless connection with industrial automation systems and ABB intelligent monitoring platforms.

Main Functions

It realizes high-precision automatic voltage regulation (AVR) for synchronous generators and motors, maintaining stable generator terminal voltage under variable load conditions. It supports reactive power regulation and power factor optimization of power generation equipment to improve power quality of the power system. It is equipped with comprehensive protection functions, including over-excitation limit (OEL), under-excitation limit (UEL), V/Hz ratio limit and instantaneous current limit (SCL), which can effectively avoid equipment damage caused by abnormal operating parameters. It integrates power system stabilizer (PSS) function to suppress low-frequency oscillation of the power grid and improve system operation stability. Meanwhile, it has complete fault diagnosis, event recording and communication diagnosis functions, facilitating on-site operation monitoring, daily maintenance and fault troubleshooting.

Product Advantages

Firstly, it has ultra-high control precision and fast dynamic response, which can quickly adapt to sudden load changes and ensure the long-term stable operation of power generation equipment. Secondly, the modular design realizes standardized installation and convenient later expansion and maintenance, reducing equipment operation and maintenance costs. Thirdly, it has excellent environmental adaptability and industrial-grade reliability, with low failure rate and long service life, suitable for long-term uninterrupted industrial operation. Fourthly, it has strong system compatibility, which can be perfectly integrated with various medium and small-capacity brushless excitation systems and mainstream industrial automation control systems. Finally, it complies with CE, UL, IEC and other international industrial standards, with high safety and universality, and has excellent cost performance in medium and small power generation excitation control scenarios.

Application Scenarios

This module is widely applicable to excitation control and voltage regulation of synchronous generators and synchronous motors with a capacity of 100kVA to 80MVA. It covers conventional thermal power plants, hydropower stations and other professional power generation scenarios, and is also suitable for industrial self-provided power stations in chemical, metallurgical, manufacturing and other industries. In addition, it can be used for marine power supply systems, rail transit backup power systems and emergency backup power generation equipment. It is applicable to both new excitation system construction projects and renovation and upgrading of old power generation control systems, providing stable and reliable core control support for various industrial power generation and power supply systems.
