Smart-tie

Smart-tie™ Automated Voltage Regulation for Grid Reliability

The Smart-tie solution is the principal component of the GridWave management solutions. Smart-tie functionality adds automated voltage regulation operation to GridWave through volt-VAR management and AC output power curtailment. As part of an overall grid voltage optimization system including standard utility practices such as using voltage regulators and capacitor banks, Smart-tie solutions complete the system by managing rapid voltage changes and solar-induced conditions at the grid secondary.

The Smart-tie package includes:

• Reactive power (volt-VAR) injection (automated)
• AC output power level curtailment (automated)

• AC output power curtailment (manual)
• Reactive power (VAR) injection (manual)
• Voltage operating window setpoints
• Frequency operating window setpoints
• Voltage ride-through controls
• Power ramp rate management

Automated Volt-VAr Benefits

Automated volt-VAR management enables seamless voltage regulations supporting
a wide variety of grid conditions.
