ExcBBC

Class Description

Transformer fed static excitation system (static with ABB regulator). This model represents a static excitation system in which a gated thyristor bridge fed by a transformer at the main generator terminals feeds the main generator directly.

Attributes

Name Type Description
efdmax PU Maximum open circuit exciter voltage (Efdmax) (> ExcBBC.efdmin). Typical value = 5.
efdmin PU Minimum open circuit exciter voltage (Efdmin) (< ExcBBC.efdmax). Typical value = -5.
k PU Steady state gain (K) (not = 0). Typical value = 300.
switch Boolean Supplementary signal routing selector (switch).
true = Vs connected to 3rd summing point
false = Vs connected to 1st summing point (see diagram).
Typical value = false.
t1 Seconds Controller time constant (T1) (>= 0). Typical value = 6.
t2 Seconds Controller time constant (T2) (>= 0). Typical value = 1.
t3 Seconds Lead/lag time constant (T3) (>= 0). If = 0, block is bypassed. Typical value = 0,05.
t4 Seconds Lead/lag time constant (T4) (>= 0). If = 0, block is bypassed. Typical value = 0,01.
vrmax PU Maximum control element output (Vrmax) (> ExcBBC.vrmin). Typical value = 5.
vrmin PU Minimum control element output (Vrmin) (< ExcBBC.vrmax). Typical value = -5.
xe PU Effective excitation transformer reactance (Xe) (>= 0). Xe models the regulation of the transformer/rectifier unit. Typical value = 0,05.
