HVDC Valves with Light-Triggered Thyristors. In: Jaecklin A.A. (eds) Power Semiconductor Devices and Circuits. Springer, Boston Cited by: 8. Abstract: The adverse impacts of commutation failure (CF) of a line-commutated converter (LCC)-based high-voltage direct current (HVdc) system on the connected ac system are becoming more serious for high-power ratings, for example, the development of ultra-HVdc systems.
Aiming to solve the problem of CF particularly for higher power/current LCC HVdc Cited by: Caption: 6-inch thyristor with corresponding silicon wafer and cross-sectional structure. Not so long ago, one of the first commercially viable high-power HVDC lines was serviced in Cahora Bassa, in Mozambique.
After about 40 years, new switchgear was installed, new transformers, new controls – new everything, except the thyristor valves. IEEE HVDC Projects list HIGH-VOLTAGE direct current (HVDC) systems have become a viable option for accommodating bulk power transmission over long distance.
They can serve as technically feasible solutions for connecting large offshore wind firms located farther than 70 km away from the coast. Thyristor monitoring The thyristor valve monitoring system is a self supervising system.
In every valve control unit there is a function, detecting if the voltage is picked up within a specified time by the corresponding thyristor. At the time the thyristor picks up the voltage an indication pulse IP is sent on an optical fiber to the valve.
Periodic firing and extinction tests on thyristor valves for HVDC and SVC applications are performed in a new facility that has the capability to test.
