Dynamic VAr compensation provides VArs to offset Dynamic VAr changes occurring elsewhere on the local power system.
This is different from meeting static (steady-state) VAr requirements. That's typically done with fixed capacitors.
This is also different form meeting very slowly changing stepped VAR demands - like those appearing when a facility goes online in the morning and disappearing when it goes offline in the evening. (We refer to these as "baseload" VAr demand and it is best met with vacuum-switched capacitors.)
Dynamic VAr compensation requires response to VAr demand in a cycle or less. It requires 3 critical pieces:
- The ability to sense instant changes in VAr requirement and determine the appropriate response.
- The ability to add and remove VARs from the power system each cycle.
- The ability to operate (switch) the Dynamic VArs millions or billions of times without causing wear to the capacitors or the switches.
To meet these requirements T-Star developed a high speed proprietary control system, and proprietary medium-voltage-rated solid state ("static") switches.
When combined with T-Star's applications expertise and off-the shelf passive components the result is a highly efficient, reliable Dynamic VAr system to meet your needs. With over 100 systems, in 20 years of field applications, Dynamic VAr systems are a proven solution.
