Abstract
The main work focus is on the LCC HVDC reactive power control system with fluid regulated AC voltage. The reactive power and the voltage control capacity of LCC HVDC were examined and demonstrated with controlled condensers. Reactive power control and voltage management have been suggested and associated controllers with variable condensers have been developed on the reverse side of the fuzzy controlled LCC HVDC system. The active corrective side power control is required and a reactive or voltage control has been taken into account in this work. This study looks at the inverter side of the system LCC HVDC with customizable capacitors, reactive power and fluid management of the AC voltage. The usual AC voltage control and PI controller for reactive power is replaced by an injected controller that enhances reaction speed and control. In the MATLAB software with Sim-Power system toolbox, graphs are created using a GUI environment to model the proposed fuzzy-controlled HVDC system.
Highlights
The switch takes place in a switched converter line by AC system voltage. This leads to problems essential to continuous, confident turning at very low ac system voltages, e.g. during breakdowns of the ac system
The HVDC (LCC HVDC) switched-line conversion converter still operates in multiple centuries MW of bulk-power transmission, as a power transmission for numerous applications is efficient, reliable and economical
This study examined and showed how reacting power and voltage control is capable of the LCC HVDC system, with its changeable condensers
