| Abstract: | Thyristor breakdown is one of the common failures of converter valves,but the solution of ± 800 kV HVDC station A5000 converter valve thyristor breakdown has problems such as time-consuming instability and complex processing links, which further prolongs the converter valve outage time and affects the power transmission capacity of the DC transmission system. This paper optimizes the thyristor breakdown fault handling scheme of the A5000 converter valve, improves the efficiency of the thyristor breakdown fault treatment of this type of converter valve, shortens the outage time of the converter valve, and can further guarantee the power transmission capacity of the DC transmission system. |
