Control System Parameters

Reference Parameters

• Vref: Voltage reference (pu) (automatic mode);
• Bref: Susceptance reference (pu/100MVA) (manual mode).
• CLC Mode: (Automatic, Manual)

Operating Mode Parameters

• TCC mode: (On = synchronized firing of the TSC capacitive branches, Off = continuous firing);
• Valve blocking and unblocking: (Deblock = valve firing enabled, Block = valve firing disabled);

Regulation Parameters
