Thyristor Voltage Regulators (TVRs)
Due to the high-speed response and frequent switching capabilities, TVRs quickly respond to current reverse flows and voltage fluctuations that occur in distributed power sources, contributing to stable electricity supply.
Characteristics
-
Suitable for distributed power sources
Thyristor voltage regulators calculate the changes in primary and secondary voltages due to each tap-change operation to determine the direction of the power flow and provide appropriate control in the event of a reverse power flow in solar photovoltaic and other power generation systems.
-
High-speed response to frequent voltage fluctuations
Minimum response speed of 140ms (no tap jumping, 500-V voltage deviation)
-
Thyristor voltage regulators reduce voltage fluctuations via tap-jumping control.
The tap-jumping feature removes voltage deviations instantaneously.
-
Tap-changing capability that supports frequent control actions
There is no limit to the number of tap changes made.
-
Maintenance-free
Due to the use contactless switches for thyristors, thyristor voltage regulators require no inspection of the tap changer.
