In many fields such as distributed generation, ship electric propulsion, diesel locomotives, and wind power, the voltage stability of synchronous generator sets and electric motors directly determines the power supply quality and equipment safety of the power system. As the core of the excitation system, the performance of the automatic voltage regulator (AVR) not only affects the regulation accuracy of the terminal voltage, but also relates to the dynamic response and fault ride through capability of the unit's grid connected operation. ABB UNITROL ® The UNITROL 1010 and 1020 in the 1000 series are highly integrated and reliable AVR solutions tailored for small and medium power applications.
Compliance services: ABB provides PSS parameter calculation, reference step response simulation, stability simulation under different grid conditions, and issues reports.
For example, for grid standards that require "low voltage ride through (LVRT)", the UNITROL 1000 can output the maximum excitation voltage within tens of milliseconds when the grid voltage drops to 0%, maintaining the transient stability of the generator.
