The challenge

Grid codes are constantly changing due to the new and unprecedented network developments.

Therefore, installed plant equipment requires to be upgraded/replaced to comply with the network

regulations which leads to increased extended outages and costs.

PSS SA is a cost-effective solution to be compliant immediately.

Why Power System Stabilizer Standalone (PSS SA)

Power system stabilizers (PSS) are commonly used to damp various types of oscillation modes,

as from interarea oscillations in large transmission networks to local oscillation modes of synchronous

generating units. This is done by adding a stabilizing signal to the voltage regulator of the existing

excitation systems.
