The invention relates to a dynamic response performance test method for a TCR (
Thyristor Controlled Reactor) type SVC (
Static Var Compensator) for large-capacity shock load. The method includes the following steps that: influences on
electric energy quality caused by a test are analyzed, a switching scheme is determined; a target reactive power value and a response lower-
limit value of a TCR is calculated; a
test point is arranged, required signals are synchronously acquired; and the actual triggering angle of the TCR is obtained, a response performance test is completed. According to the dynamic response performance test method of the TCR type SVC for the large-capacity shock load of the invention, the dynamic response performance of the TCR type SVC is evaluated according to
response time; a filtering compensation
branch is
cut off at a high-
voltage synchronous circuit breaker or other switching devices when current crosses a zero point,
bus-bar
voltage, total incoming current, the feeder current of the
cut-off filtering compensation
branch, and the phase current of the TCR are acquired; the
zero crossing cutoff point of the feeder current of the filtering compensation
branch is adopted as a zero time point; a triggering
delay angle corresponding to 10% of the target reactive power value of the TCR is the response lower-
limit value; a time point when the actual triggering angle in the phase current waveforms of the TCR is larger than the response lower-
limit value is a
response time point; and the difference value of the zero time point and the
response time point is the response time.
