Abstract
A reactive power compensator includes a plurality of phase clusters each including a plurality of cells, and a controller configured to control the plurality of phase clusters. When an energy error is generated in each of the plurality of phase clusters, the controller performs control to compensate for the energy error by generating an offset signal having a zero sequence component based on an error energy value of each of the plurality of phase clusters.
Claims23
A reactive power compensator for compensating for reactive power of a power system, the reactive power compensator comprising:
- a plurality of phase clusters, each including a plurality of cells;
- and
- a controller configured to control the plurality of phase clusters,
- wherein, when an energy error is generated in each of the plurality of phase clusters, the controller performs control to compensate for the energy error by generating an offset signal having a zero sequence component based on an error energy value of each of the plurality of phase clusters.
A method of controlling a reactive power compensator for compensating for reactive power of a power system, the method comprising:
- generating an offset signal having a zero sequence component based on an error energy value of each of a plurality of phase clusters when an energy error is generated in each of the plurality of phase clusters;
- generating a command value reflecting the offset signal having the zero sequence component;
- and
- compensating for the energy error by controlling each of the plurality of phase clusters by using the command value.
