Basic InformationBrand: ABB

Type: Excitation Control Equipment

Technical Specifications1. Input Voltage Range: Capable of accommodating a wide range of input voltages. The typical AC input voltage range is 100 – 240V AC, 50/60Hz, to meet the requirements of different power grid environments.2. Output Control: The output signal can precisely control the excitation current, thereby regulating the generator’s output voltage. For instance, the control accuracy of the generator terminal voltage can be maintained within ±0.5%.3. Communication Interfaces: Equipped with multiple communication interfaces, such as Ethernet and RS485, facilitating data exchange and remote monitoring with other devices, and supporting common industrial communication protocols like Modbus and Profibus.4. Sampling Frequency: High-speed sampling of the generator’s voltage, current, and other signals, with a sampling frequency generally reaching 1000Hz or higher, to enable fast and accurate control response.

Features1. Precise Voltage Regulation: Adjusts the excitation current in real time according to changes in generator load and system voltage fluctuations, maintaining stable generator output voltage to ensure power supply quality.2. Reactive Power Control: Effectively distributes reactive power in scenarios with multiple generators operating in parallel, improving power system stability and power factor while reducing line losses.3. Protection Functions: Equipped with comprehensive protection mechanisms such as overvoltage protection, undervoltage protection, overcurrent protection, over-excitation protection, and loss of excitation protection. It can respond quickly in abnormal situations to prevent equipment damage and accident escalation.4. Automatic and Manual Switching: Supports both automatic and manual control modes. In automatic mode, it can automatically adjust excitation based on set parameters and collected signals; manual mode facilitates debugging and manual intervention under special circumstances.5. Fault Diagnosis and Display: Built-in fault diagnosis capabilities allow rapid identification of equipment fault points and output fault information via display screen or communication interface, making maintenance and repair convenient for operators.
