This system integrates ABB's advanced technologies in the fields of power electronics and automatic control, and has a high level of reliability, flexibility and intelligence. Its design complies with international general power industry standards, can seamlessly interface with different types of synchronous motors and power systems, and is widely used in thermal power generation, hydropower generation, industrial drive and other fields. Whether it is large generator sets or small and medium-sized industrial synchronous motors, UNS0119A-Z,V1 3BHE030579R0001 can rely on its excellent performance to meet the excitation control needs in different scenarios, providing strong support for the safe and stable operation of power systems.

II. Technical Parameters

Electrical Parameters
Power Input: Supports multiple power input modes, usually including AC and DC power supplies. The AC power input range is generally 110-240V AC, 50/60Hz; the DC power input range is commonly 24-110V DC, which can adapt to different on-site power supply conditions and ensure that the system can start and operate stably in various power environments.
Excitation Output: The maximum excitation current and voltage can be configured according to different motor models and capacities. For example, the maximum excitation current can reach several thousand amperes, and the maximum excitation voltage can reach several hundred volts, which can provide sufficient excitation power for synchronous motors of different power levels to meet the excitation needs of the motors.
Power Consumption: In normal working conditions, the system has low power consumption, usually not exceeding a certain value (such as 500W). The low-power design is not only conducive to energy saving, but also reduces the heat generation during the operation of the system, improving the stability and service life of the equipment.

Control Parameters
Regulation Accuracy: The voltage regulation accuracy is extremely high, usually not exceeding ±0.5%, which can accurately control the terminal voltage of the synchronous motor, ensure the stability of the motor output voltage, and reduce the impact of voltage fluctuations on the power system.
Response Time: It has a fast response speed to changes in grid voltage and load, with a response time generally within tens of milliseconds. It can quickly adjust the excitation current to maintain the stable operation of the motor and improve the dynamic stability of the power system.
Control Modes: Supports multiple control modes, including constant voltage control, constant excitation current control, constant reactive power control, etc. Users can flexibly choose according to actual operation needs to meet the control requirements under different working conditions.

Environmental Parameters
Operating Temperature: The operating temperature range is usually -10℃ to +55℃, with good adaptability to ambient temperature. It can work normally in different climatic conditions such as cold winters and hot summers, ensuring uninterrupted excitation control of the synchronous motor.
Relative Humidity: It can operate stably in an environment with a relative humidity of 5%-95% (non-condensing). The system adopts advanced moisture-proof technology and sealing design inside, which effectively prevents humid air from eroding the internal circuits, and is suitable for humid environments such as hydropower stations and industrial workshops.
Anti-vibration Performance: It can withstand vibrations of certain frequency and acceleration, such as vibrations with a frequency of 10-150Hz and an acceleration of 0.5g. In the vibration environment generated during the operation of the motor, it will not affect the normal working performance of the system, ensuring the reliability of excitation control.

III. Functional Features

Precise Excitation Regulation Function
UNITROL1020 adopts advanced digital control algorithms, which can real-time monitor the operating parameters of synchronous motors, such as terminal voltage, excitation current, reactive power, etc., and accurately adjust the excitation current according to the monitoring results. When the grid voltage or load changes, the system can respond quickly, adjust the excitation output, maintain the stability of the motor terminal voltage, and ensure the normal operation of the motor and the stability of the power system.

It has strong reactive power regulation capability, which can automatically adjust the reactive output of the synchronous motor according to the reactive demand of the power grid, realize the reactive power balance of the power grid, improve the power factor of the power grid, and reduce power loss.

Comprehensive Protection Functions
It has comprehensive protection functions, including over-excitation protection, under-excitation protection, over-voltage protection, over-current protection, loss of excitation protection, etc. When abnormal conditions occur in the synchronous motor or excitation system, the protection function can act quickly, cut off the excitation circuit or issue an alarm signal to prevent the expansion of faults and protect the safety of the motor and equipment.

It has the function of excitation winding overheating protection. By monitoring the temperature of the excitation winding, when the temperature exceeds the set value, it can timely take measures such as reducing excitation or shutting down to avoid damage to the excitation winding due to overheating.

Flexible Operation and Control Modes
It supports two control modes: local control and remote control. Local control can be operated through the buttons and display screen on the control panel, which is convenient for on-site debugging and maintenance; remote control can be realized through the communication network, and operators can set parameters, monitor the operating status and perform control operations on the excitation system in the control center, which improves the operational convenience and automation level of the system.

It can cooperate with the starting system of the synchronous motor to realize smooth starting and grid-connected operation of the motor. During the motor starting process, it can accurately control the excitation current to ensure that the motor starts smoothly and reaches the synchronous speed, reducing the impact on the power grid during the starting process.

Intelligent Monitoring and Diagnostic Functions
It has a strong real-time monitoring function, which can continuously monitor various operating parameters of the excitation system, such as excitation voltage, excitation current, thyristor firing angle, motor terminal voltage, etc., and display the monitoring data on the display screen in real-time or upload it to the monitoring system, providing operators with comprehensive system operating status information.

It has a perfect fault diagnosis function, which can automatically detect internal faults of the system, such as sensor faults, thyristor faults, communication faults, etc., and prompt the fault type and location through the display screen or alarm signal, facilitating maintenance personnel to quickly locate and eliminate faults, shorten the fault handling time, and improve the availability of the system.

High Reliability and Stability
The system adopts a modular design, and each functional module is independent of each other, which is convenient for maintenance and replacement. At the same time, key components adopt redundant design, such as power modules and control modules. When a component fails, the redundant component can automatically put into operation to ensure the uninterrupted operation of the system and improve the reliability of the system.

It has strong anti-interference ability, can resist the influence of harmonics, electromagnetic interference and other factors in the power grid, ensure that the system works stably in complex electromagnetic environments, and ensure the accuracy and reliability of excitation regulation.
