ABB UNITROL 1010-0004 BASIC+SYNC 3BHE035301R0004

The ABB UNITROL 1010-0004 BASIC+SYNC (3BHE035301R0004) is a specific model of the UNITROL 1010 excitation controller series. Here is a detailed introduction:

Features

Advanced Control Algorithm: It adopts advanced microprocessor - based control algorithms, which can precisely control the excitation current of the synchronous generator to ensure the stability of the generator's output voltage and reactive power.

Integrated Synchronization Function: The "SYNC" in the model name indicates that it has an integrated synchronization function. This allows the generator to be smoothly synchronized with the power grid or other generators, reducing the impact on the power system during the synchronization process.

Comprehensive Protection Mechanisms: It is equipped with various protection functions, including over - voltage protection, over - current protection, over - temperature protection, and under - excitation protection. These protection mechanisms can quickly detect and respond to abnormal conditions, protecting the generator and excitation system from damage.

Good Communication Capability: It has built - in communication interfaces, such as RS - 485 or Ethernet, which can easily communicate and exchange data with the upper - level monitoring system. This enables remote monitoring, parameter setting, and fault diagnosis of the excitation controller.

Functions

Voltage Regulation: It continuously monitors the terminal voltage of the generator and adjusts the excitation current in real - time through a feedback control loop to maintain the output voltage at a set value. The voltage regulation accuracy can reach a very high level, usually within ±0.5% or better.

Reactive Power Control: According to the reactive power requirements of the power system, the controller can automatically adjust the excitation level of the generator to control the reactive power output. This helps to maintain the power factor of the power system within a reasonable range and improve the stability and efficiency of the power grid.

Synchronization Control: When the generator needs to be connected to the power grid or paralleled with other generators, the integrated synchronization function of the UNITROL 1010 - 0004 can precisely control the generator's frequency, voltage, and phase to ensure a smooth and stable synchronization process.

Fault Diagnosis and Alarm: The controller continuously monitors the operating status of the excitation system and the generator. When a fault is detected, it can quickly identify the type and location of the fault and send out an alarm signal. At the same time, it records the fault information for subsequent analysis and troubleshooting.

Applications

Power Generation in Power Plants: It is widely used in various power plants, such as thermal power plants, hydropower plants, and gas - fired power plants, to control the excitation of synchronous generators and ensure the stable operation of the power generation equipment and the quality of power supply.

Industrial Self - Generation Systems: In some large industrial enterprises, there are self - generation systems to meet their own power needs. The UNITROL 1010 - 0004 can be used in these systems to control the excitation of generators and ensure the reliable operation of the self - generation equipment.

Renewable Energy Power Generation: In renewable energy power generation projects such as wind power and photovoltaic power generation, when synchronous generators are used, the UNITROL 1010 - 0004 can be used to control the excitation of generators to improve the stability and power quality of renewable energy power generation and ensure its reliable connection to the grid.
