METHOD AND SYSTEM FOR A GAS TUBE SWITCH BASED VOLTAGE SOURCE HIGH VOLTAGE DIRECT CURRENT TRANSMISSION SYSTEM
摘要
A voltage source converter based high-voltage direct-current (HVDC) transmission system includes a voltage source converter (VSC)-based power converter channel. The VSC- based power converter channel includes an AC -DC converter and a DC-AC inverter electrically coupled to the AC -DC converter. The AC-DC converter and a DC-AC inverter include at least one gas tube switching device coupled in electrical anti-parallel with a respective gas tube diode. The VSC-based power converter channel includes a commutating circuit communicatively coupled to one or more of the at least one gas tube switching devices. The commutating circuit is configured to "switch on" a respective one of the one or more gas tube switching devices during a first portion of an operational cycle and "switch off the respective one of the one or more gas tube switching devices during a second portion of the operational cycle.
