Research on DC component decay time constant of 1000 kV AC filter circuit breakers in UHV converter station

Research on DC component decay time constant of 1000 kV AC filter circuit breakers in UHV converter station

In hierarchically connected UHV DC projects, the 1000 kV AC filter sub-bank in converter station is provided with two 500 kV circuit breakers. To determine the test DC component decay time constant when breakers break short-circuit current, relevant DC project was modelled in electromagnetic transie...
