Technical Description of Static Compensators (STATCOM)
The static synchronous compensator (STATCOM), previously referred to as the static condenser (STATCON) or advanced static var compensator (ASVC) or self-commutated static var compensator, is a shunt-connected reactive power compensa-tion equipment which is capable of generating and/or absorbing reactive power
Step-by-Step Process to Calculate a DC-to-DC Compensation …
The Compensator. The LC filter causes a phase loss. A compensating network is used to provide a phase boost. It adds poles and zeros to the loop to counter the phase lag, or lead, and gain changes that were caused by the LC filter. ... If R1 is increased, the compensator capacitors need to be decreased by the same ratio to keep the time ...
