ABB excitation system is a key equipment used in large thermal power units and nuclear power plants. Its basic function is to use closed-loop or feedback control to provide continuous DC current to the excitation winding of synchronous motors. This system plays an important role in stabilizing power output and is a core component of many generator sets.

The ABB excitation system adopts advanced UNITROL automatic voltage regulator (AVR) and static excitation system (SES), providing high return on investment solutions for various types of power plants. ABB's UNITROL ® 1000 and UNITROL ® The 6000 series can meet the needs of both power generation and non power generation applications. The UNITROL 1000 series is ABB's brushless excitation system for synchronous motors with capacities ranging from 100kVA to 80MVA. It has been applied in over 20000 projects, including power plants, ship propulsion and auxiliary power sources, diesel electric locomotives, port cranes, and heavy-duty vehicles in mining areas.

The ABB excitation system combines automation, electrical systems, rotating machinery control, instrumentation, and advanced digital equipment to provide reliable services for power generation facilities. With the development of global grid regulations, ABB will continue to invest in advanced technology and standards to ensure the optimal adaptability of its excitation system.

The core technologies of ABB excitation system mainly include the following aspects:

DSP digital signal processing technology: This is an advanced digital signal processing technology that can monitor and analyze the operation status of generator sets in real time, achieving precise control and adjustment.

Dynamic and intelligent current sharing technology of controllable silicon rectifier bridge: Through precise control of the controllable silicon rectifier bridge, the balanced distribution of current is achieved, improving the operational efficiency and stability of the generator set.

Low residual voltage fast excitation technology: In case of system failure or startup, it can quickly provide sufficient excitation current to quickly establish voltage in the generator set, ensuring stable operation of the power system.

Comprehensive communication functions and various debugging methods: With powerful communication functions, remote monitoring and debugging can be achieved, making it convenient for users to troubleshoot and maintain the system. At the same time, multiple debugging methods are provided to facilitate users to debug and optimize equipment on site.

ARCnet network technology: This is an efficient network communication technology that enables fast data exchange and information sharing between devices, improving the overall performance and reliability of the system.
