Simulation Study on Reactive Power Compensation of Line Modification for 220 kV Substation
摘要
针对220 kV变电站出线上改下工程中
因架空出线改电缆后容性充电功率大量增加的问题

Abstract
In view of the line modification of 220 kV substation and since the capacitive charging power increases significantly after the modification of overhead line into cable
in this paper
the simulation calculation for the check point voltage and active power loss of network before and after inductive reactive power compensation are made on the basic principle of the reactive power compensation of network and in accordance with the actual parameters of equipment and light load typical daily load.It is shown by the calculation result that the dispersion compensation scheme of the reactor is superior to the centralized on the premise of meeting the assessment criteria of meeting reactive power balance and relative bus voltage.
