ABB 3BHB045647R0003
Product Description
The ABB 3BHB045647R0003 is an excitation controller module designed to regulate the excitation system of generators1. It plays a crucial role in ensuring the stable voltage and frequency output of generators, thereby maintaining the stability of the power grid1. It is widely used in various power generation scenarios, including traditional power plants, renewable energy systems such as wind and hydro – power generation, as well as in the power generation systems of ships and offshore platforms1. In emergency backup power systems, it also ensures the provision of stable backup power during grid failures1.
Product Parameters
- Input Voltage: Usually accepts a specific range of DC or AC voltages, such as 110V DC or 220V AC, to meet different power supply requirements.
- Output Current: Capable of providing a certain range of output currents to meet the excitation current demands of different generators.
- Control Accuracy: Achieves high – precision control of excitation current, with voltage control accuracy typically within ± 0.5% and frequency control accuracy within ± 0.1%.
- Response Time: Has a fast response time, usually within milliseconds, to quickly adjust the excitation current according to changes in generator load.
