User low-voltage management method based on plug-and-play mobile svc

Abstract

The invention discloses a user low-voltage management method based on a plug-and-play mobile SVC. The implementation steps include determining the load size and low-voltage amplitude of the target user; The installation capacity Q of the ready-to-use mobile SVC; the plug-and-play mobile SVC with an installation capacity not less than Q is installed at the incoming line of the target user, and the reactive power voltage compensation is performed on the target user through the plug-and-play mobile SVC. Realize the low voltage management of target users. Based on the monitored and tested low-voltage conditions of users, the invention installs a set of plug-and-play mobile SVC to control the user voltage, which can make the voltage reach the qualified target and meet the normal electricity consumption needs of residents. The plug-and-play The mobile SVC is convenient to charge, suitable for household and decentralized installations, and can effectively solve the problem of low voltage during peak load hours for residents.

Description

technical field [0001] The invention relates to a dynamic reactive voltage control technology of a distribution network, in particular to a user low-voltage management method based on a plug-and-play mobile SVC. Background technique [0002] At present, rural areas are affected by power supply radius, old lines, and large load fluctuations. There is a low voltage situation during user load peak periods, which affects the normal power consumption of user air conditioners, rice cookers and other electrical appliances, and cannot meet people's daily electricity demand. Conventional methods such as adjusting the 10kV voltage bus of the upper substation and distribution transformers can solve the voltage quality of some users, but it is difficult to solve the problem of low voltage of end users during peak load hours; through methods such as increasing the capacity of distribution transformers and upgrading and transforming lines, there are large investment, Due to limitations su...

Problems solved by technology

[0002] At present, rural areas are affected by power supply radius, old lines, and large load fluctuations. There is a low voltage situation during user load peak periods, which affects the normal power consumption of user air conditioners, rice cookers and other electrical appliances, and cannot meet people's daily electricity needs.

Conventional methods such as adjusting the 10kV voltage bus of the upper substation and distribution transformers can solve the voltage quality of some users, but it is difficult to solve the problem of low voltage of end users during peak load hours; through methods such as increasing the capacity of distribution transformers and upgrading and transforming lines, there are large investment, Due to limitations such as long time, it is not suitable for large-scale investment and application at the end of power supply

Static Var Compensation (StaticVar Compensation, SVC) is currently the most widely used and most mature parallel reactive power compensation equipment in the power system, which can realize the dynamic adjustment of the voltage at the installation point, but the small-sized household SVC has not been obtained in the low-voltage users. application
