Switched Shunt Model: MSS1

 

Model Equations and/or Block Diagrams

 

Parameters:

Vlow1 Voltage threshold Vlow1 (p.u.)
Vlow2 Voltage threshold Vlow2 (p.u.)
Vhigh1 Voltage threshold Vhigh1 (p.u.)
Vhigh2 Voltage threshold Vhigh2 (p.u.)
Tbrk Time required by MSS breaker to operate (sec.)
Tdlow1 Time dlow 1 for switching in (sec.)
Tdlow2 Time dlow 2 for switching in (sec.)
Tcount Capacitor lock out time (sec.)
Tdhigh1 Time dhigh 1 for switching in (sec.)
Tdhigh2 Time dhigh 2 for switching in (sec.)

footnotes: This model is the dame as MSS1 but the difference is that the timers (Tdlow1, Tdhigh1) and (Tdlow2, Tdhigh2) are operated and evaluated independently.
