Abstract
A system including a multi-level converter including a plurality of valve sections including a plurality of sub modules, a plurality of VCU controllers connected to each of the plurality of valve sections, and an upper controller connected to the plurality of VCU controllers, wherein the VCU controller is configured to receive status information from each of the plurality of sub modules to transmit the state information to the upper controller, receive a specific sub module control command information from the upper controller, and transmit the control command information to a specific sub module among the plurality of sub modules.
Claims8
A system including a multi-level converter including a plurality of valve sections including a plurality of sub modules, a plurality of Valve Connection Unit (VCU) controllers connected to each of the plurality of valve sections, and an upper controller connected to the plurality of VCU controllers,
- wherein each VCU controller of the plurality of VCU controllers is configured to:
- receive status information from each of the plurality of sub modules to transmit the status information to the upper controller,
- receive control command information for a specific sub module of the plurality of sub modules from the upper controller,
- transmit the control command information to the specific sub module among the plurality of sub modules,
- check whether a software upgrade is required for the plurality of sub modules included in a corresponding valve section, and
- transmit a program required for the software upgrade to each sub module in the corresponding valve section through a sub module controller disposed between the plurality of sub modules and the VCU controller.
A Valve Connection Unit (VCU) controller connected to a multi-level converter including a plurality of valve sections including a plurality of sub modules, and each of the plurality of valve sections,
- wherein the VCU controller is configured to:
- receive status information from each of the plurality of sub modules to transmit the status information to an upper controller, in communication with the VCU controller,
- receive control command information for a specific sub module of the plurality of sub modules from the upper controller,
- transmit the control command information to the specific sub module among the plurality of sub modules,
- check whether a software upgrade is required for the plurality of sub modules included in a corresponding valve section of the plurality of valve sections, and
- transmit a program required for the software upgrade to each of the sub modules through a sub module controller disposed between the plurality of sub modules and the VCU controller.
