Description
ABB UNITROL 1010 3BHE035301R1002 is an advanced digital automatic voltage regulator (AVR), mainly applied to small and medium-sized synchronous generator systems. It aims to provide precise and stable excitation control for the generator to ensure that the generator can output a stable voltage under various working conditions, meeting the power quality requirements of different users. Functional Features Precise Voltage Regulation: By using advanced microprocessor technology and complex control algorithms, it can monitor the output voltage of the generator in real time and quickly and precisely adjust the excitation current according to the load changes. The voltage regulation accuracy can be controlled within a very small range, such as ±0.5% or higher, effectively reducing voltage fluctuations and providing a stable and reliable power supply for the devices connected to the generator. Rich Communication Interfaces: Equipped with a variety of communication interfaces, such as RS232, RS485, and Ethernet, etc., it supports multiple industrial communication protocols such as Modbus and Profibus. This enables the device to be conveniently connected to and exchange data with other devices (such as monitoring systems, PLCs, etc.), realizing remote monitoring and control. Operators can obtain the operating parameters of the generator (such as voltage, current, power factor, etc.) in real time through the upper computer and perform parameter settings and fault diagnosis on the voltage regulator. Complete Protection Functions: It has a comprehensive built-in protection mechanism, including overvoltage protection, undervoltage protection, overcurrent protection, frequency protection, etc. When abnormal situations occur in the generator or the system, these protection functions can act quickly and take corresponding measures (such as limiting the excitation current, cutting off the circuit, etc.) to protect the generator and other devices from damage and improve the safety and reliability of the system. High Reliability and Stability: Adopting high-quality electronic components and a sturdy and durable hardware design, it has strong anti-interference ability and can operate stably in harsh industrial environments. Its operating temperature range is relatively wide, generally from -25°C to +70°C, and it has good dust-proof and moisture-proof performance, which can adapt to different working environment conditions. In addition, the device also has a self-diagnosis function, which can monitor its own working status in real time, and promptly detect and report potential faults. Flexible Configuration and Debugging: It supports flexible parameter configuration, and users can set various parameters of the voltage regulator according to actual needs, such as voltage setting value, regulation gain, time constant, etc. At the same time, it also provides a user-friendly human-machine interface and debugging tools, facilitating technicians to install, debug and maintain the device.
Technical Parameters Power Input: Usually, it requires an AC power input of 120V AC to maintain the normal operation of the device. At the same time, it may also be equipped with a backup power source or a power management module internally to ensure that the device can still operate normally for a certain period of time in case of a main power failure. Rated Current: The rated current is 0.5A, which can provide sufficient current for the excitation winding of the generator to achieve effective excitation control. Control Precision: The voltage regulation precision can reach ±0.5% or higher, ensuring the stability of the generator's output voltage. Response Time: It has a relatively fast response speed to load changes and can adjust the excitation current within dozens of milliseconds to restore the voltage to the set value, ensuring the dynamic performance of the system. Storage Temperature: The storage temperature range is from -40°C to +85°C, which means that the device can be stored within a relatively wide temperature range when not in use without significantly affecting its performance. Weight: The weight of the device is approximately 2.9 kilograms, and the shipping weight is approximately 3.3 kilograms, making it easy to install and transport.
Application Scenarios:
Industrial Self-owned Power Plants: Many large industrial enterprises, such as those in the iron and steel, chemical, and paper-making industries, will build their own self-owned power plants to ensure the stability and reliability of power supply during the production process. In these self-owned power plants, ABB UNITROL 1010 3BHE035301R1002 can be used for the excitation control of synchronous generators to ensure that the generator can output a stable voltage under different production load changes, meeting the power quality requirements of various production equipment within the enterprise. For example, in an iron and steel plant, equipment such as electric arc furnaces and rolling mills will cause large load fluctuations during operation. This voltage regulator can respond quickly and adjust the excitation of the generator to maintain voltage stability and ensure the smooth progress of production.
Small Hydropower Stations: Small hydropower stations usually install small and medium-sized synchronous generators to convert water energy into electrical energy and transmit it to the power grid or directly supply it to surrounding users. ABB UNITROL 1010 3BHE035301R1002 can precisely control the output voltage of the generator to match it with the grid voltage and achieve stable grid connection operation. At the same time, in the single-unit operation mode of the hydropower station, it can also ensure that the generator outputs a stable voltage, providing a reliable power supply for surrounding residents and small industrial users.
Marine Power Systems: The power systems on ships need to supply power to numerous devices, including the propulsion system, navigation equipment, communication systems, and living facilities, etc. Since ships will be affected by various factors during navigation, such as load changes and wave impacts, the stability of the power system faces challenges. This voltage regulator can monitor and adjust the voltage of the generator in real time to ensure the stable operation of the marine power system and provide a guarantee for the safe navigation of the ship and the normal operation of various devices. For example, on an ocean-going cargo ship, whether it is sailing under heavy load or light load, ABB UNITROL 1010 3BHE035301R1002 can effectively adjust the generator voltage to meet the power needs of different devices on the ship.
Mobile Power Generation Equipment: Some mobile power generation equipment, such as emergency generator sets and power generation devices on engineering vehicles, etc., will also use ABB UNITROL 1010 3BHE035301R1002. In emergency situations, these mobile power generation equipment need to start quickly and provide a stable power supply to meet emergency power needs. This voltage regulator can respond quickly and adjust the voltage of the generator to ensure that the output power meets the requirements of the electrical equipment. For example, at the scene of a natural disaster rescue, the emergency generator set can provide stable power for rescue equipment, lighting facilities, etc. through this voltage regulator, ensuring the smooth progress of the rescue work.
