Voltage compensation method and system for power distribution network, computer equipment and storage medium

Abstract

The invention relates to a voltage compensation method and system for a power distribution network, computer equipment and a storage medium. The voltage compensation method for the power distribution network is applied to a voltage compensation system comprising a voltage compensation circuit. The voltage compensation circuit comprises a first thyristor assembly, a second thyristor assembly and an energy storage control circuit. A control system in the voltage compensation system receives a detection result of whether voltage sag occurs on a first feeder line, controls an energy storage control circuit to actively disconnect a first thyristor assembly under the condition that voltage sag occurs on the first feeder line, supplies power to an electricity load through the energy storage control circuit, controls a standby power supply to conduct a second thyristor assembly, and supplies power to the electric load through the second thyristor assembly. By adopting the method, the power supply switching time consumption can be reduced, and the influence and loss on the voltage-sensitive load are further reduced.

Description

technical field [0001] The present application relates to the technical field of electric power systems, in particular to a voltage compensation method, system, computer equipment and storage medium for a distribution network. Background technique [0002] With the continuous expansion of industrial scale, users have higher and higher requirements for power quality. Once a voltage sag or interruption occurs in the distribution network, it will cause huge economic losses to users, especially for those connected to the distribution network. voltage sensitive loads. [0003] In traditional technology, a dual-circuit power supply method is usually used to solve the problem of voltage sags or interruptions. Specifically, two thyristors are used to switch the main and standby power supplies. Switch the standby power supply to supply power to the electric load. [0004] However, switching of thyristors still takes a certain amount of time, so short-term voltage sags or interrupti...

Problems solved by technology

[0004] However, it still takes a certain time for thyristor switching, so short-term voltage sags or interruptions will still occur in the entire distribution network, which will affect and cause losses to voltage-sensitive loads
