ABB 3BHE02195R0124 excitation control unit

Application scenarios

Thermal power plant: In a thermal power unit, it is used to control the excitation system of a steam turbine generator. When the load of the power grid changes, quickly adjust the excitation current to maintain the stability of the generator terminal voltage, and adjust the reactive power output according to the requirements of the power grid dispatch to improve the stability of the power grid. For example, when the unit is connected to the grid for operation, it can cooperate with the power grid to achieve automatic allocation of reactive power and reduce line losses.

Hydroelectric power station: Suitable for excitation control of hydro generators to cope with load fluctuations caused by unstable water flow. By dynamically adjusting the excitation, the generator ensures stable operation under different water head and flow conditions, while participating in frequency and voltage regulation of the power grid, improving the grid connection performance of the hydropower system.

Large industrial motors: used for excitation control of large synchronous motors (such as rolling mill motors, compressor motors) in industries such as steel and chemical. By stabilizing excitation, the power factor of the motor is improved, energy consumption is reduced, and the smoothness of the motor during starting and braking is ensured, thereby extending the service life of the equipment.

New energy support: As the excitation control core of generators in new energy power plants such as biomass energy and garbage power generation, it ensures the stable grid connection between the new energy power generation system and the power grid, and meets the strict requirements of the power grid for voltage and frequency.
