Abstract

The application relates to a line voltage regulation system and a line voltage regulation method. The line voltage regulation system comprises a signal acquisition device, a control device, a thyristor voltage regulator, a reactive power compensation device and a power supply device. The signal acquisition device collects an input voltage signal of a distribution network line; the control device is electrically connected and in signal connection with the signal acquisition device to enable the input voltage signal of the distribution network line to enter the control device; and the thyristorvoltage regulator receives the command of the control device and executes the voltage regulation operation. The signal acquisition device collects the voltage regulated and controlled by the thyristorvoltage regulator; and the reactive power compensation device receives the command of the control device and compensates the reactive vacancy of the power distribution network. The line voltage regulation system and the line voltage regulation method can solve the problem that a voltage regulating effect of the conventional distribution network voltage regulating device is unstable.

Description

technical field [0001] This application relates to the technical field of distribution network line voltage control, in particular to a line voltage regulation system and a line voltage regulation method. Background technique [0002] In recent years, my country's distribution network construction investment has continued to increase. Remarkable results have been achieved in the development of distribution network. However, there are still outstanding problems in my country's distribution network at this stage. my country's distribution network has the characteristics of too long line power supply radius, insufficient distribution of substations, and single power supply. These characteristics determine that there are serious voltage limit problems in some areas. Especially in the rural distribution network, the transformation cycle is long, the load growth is fast, and the power consumption period is concentrated, and the voltage at the end of the line often exceeds the low...
