Influence of Charging Power of Cable on Voltage and Reactive Power

摘要

The wide application of cable brings a lot of charging power, which leads to the surplus of reactive power and the high voltage of the system. This paper discusses the theoretical calculation of charging power of the cable in detail, and analyzes the influence of charging power on voltage and reactive power under small load mode combined with the specific example of Fenghuangshan power supply area in Wuhan, Hubei Province. Finally, some control measures such as installing inductive reactive power compensation device are proposed.
