ABB UNS0869A-P 3BHB001337R0002 Power System Stabiliser
Product Description
ABB UNS0869A-P 3BHB001337R0002 Power System Stabiliser is a key component designed to improve the dynamic stability of power systems, especially in synchronous generator or transmission network environments. Power System Stabilizer plays a role in enhancing the stability of the entire system, helping to mitigate power system oscillations and avoid instability during transient disturbances.
PSS provides damping for low frequency oscillations that are common in power systems during transient events. If these oscillations are not effectively damped, they can lead to system instability or even blackouts.
PSS helps improve the dynamic response of power systems by providing feedback control to adjust the excitation of synchronous generators in real time. By doing so, it helps maintain stable operation during voltage changes, load fluctuations, or network disturbances.
Typically, PSS is integrated into the excitation system of a synchronous generator, working in conjunction with the excitation controller to regulate the excitation current. This ensures that the generator responds effectively to load changes and maintains stable voltage conditions.
Frequently asked questions about the product are as follows:
-ABB UNS0869A-P What does a power system stabilizer do?
A power system stabilizer improves the stability of the power system by suppressing low-frequency oscillations in synchronous generators and the transmission network.
-How does a PSS improve system stability?
It adjusts the excitation current to stabilize the performance of the generator, suppressing oscillations that cause instability, voltage fluctuations or frequency changes caused by load changes or faults.
-How does a PSS interact with the excitation system?
The PSS is integrated with the excitation system of the synchronous generator. It sends control signals to the automatic voltage regulator, which adjusts the excitation current in real time to stabilize the generator voltage and mitigate any oscillations caused by grid disturbances.
