Does the need for a PSS depend on location?
According to NERC/WECC requirements where PSS are utilized, their activity are to be reported and it is likely that performance testing of the generator excitation system will become mandatory. The PSS-100 offers built in features to perform step tests and automatically log the data to ease the burden of performing required tests and provide permanent records for future analysis. • Various self-generated test signals are available to inject internally to the PSS-100 or externally into the excitation system. Test signals include Sine, Step, Sine Sweep, and Square Wave modes. • Dedicated input for external test signal generators. • Software controlled switches allow test signal insertion at different points in stabilizer algorithm. • Data logging of PSS-100 internal variables for test results review. • Programmable logic and serial commands to control tests and data logs. • Dynamic System Analyzer and Sequence of Events Today, as test tools are part of the excitation system setup softwar
