Abstract

The invention discloses a 10kV line looped network power supply transfer method. The method comprises the following steps: S1, establishing a line model for 10kV power supply area lines with contact;S2, collecting line parameters, protection information and electrical load conditions of each 10kV power supply line according to the contact conditions; S3, comparing the line load with the line parameter information, and extracting a contact line capable of performing power supply mode transfer; and S4, performing intelligent construction and application of a power supply transfer scheme. An original 10kV power distribution network power supply transfer method is extensive and low in efficiency, and only the power supply transfer scheme and the whole-line power supply transfer in the stationcan be roughly determined. However, the 10kV line looped network power supply transfer method provided by the invention can specifically aim at a certain section and a certain part of a line, it is guaranteed that power supply transfer of part of line sections can be achieved according to accessed nodes during power failure below a certain node, and compared with the prior art, the method is moreaccurate and specific, and the self-healing efficiency after power failure is higher.

Description

technical field [0001] The invention belongs to the technical field of power supply and distribution, and specifically relates to a 10kV line ring network transfer power supply method. Background technique [0002] With the rapid advancement of urbanization, the construction of urban distribution network is also constantly planned, constructed and changed according to the needs, and it is becoming more and more complicated. At the same time, in order to improve the reliability of urban power supply, the urban area has gradually formed a pattern of ring network power supply, providing basic and high guarantee conditions for residential and commercial electricity consumption. However, due to the continuous changes in the construction of the urban ring network and the form of electricity consumption, the operational pressure and the difficulty of operation and maintenance management of the urban ring network have increased. In addition, in recent years, "intelligent distribute...
