Abstract

The invention relates to a distribution network 10 kV line load transfer path on-line selection system and belongs to the technical field of electric power. The system comprises a master server and working stations. The maser server comprises a data interface, a storage and a processor. Each working station comprises a data interface and a processor. Each data interface comprises a data interface module, the storage comprises a database module, and each processor comprises a topology module and a transfer path analysis module. Each data interface module obtains CIM file data and E file data from an SCADA system. A data analysis module analyzes CIM files and E files, and then the analyzed files are stored in the database module. Each topology module is responsible for topology generation and simplification, and topology data are generated and simplified according to device parameters and the connection relation. Each transfer path analysis module analyzes the load transfer path in each 10 kV line. Compared with the prior art, the distribution network 10 kV line load transfer path on-line selection system has the advantages of being high in calculation speed, high in practicability and high in accuracy and being applied in multiple aspects.

Description

Technical field [0001] The invention belongs to the field of electric power technology, and particularly relates to an online selection system for a transfer path. Background technique [0002] With the development of distribution network and the improvement of society's requirements for power supply reliability, there are more and more wiring forms of dual power supply or even multi-power supply in the distribution network. When a bus, switch, or feeder needs to be repaired or fails, the load on the bus, switch, or feeder powered by multiple power sources can perform load transfer. Through the loop operation, the load is transferred to the other bus or connected to it. Feeder, so as to achieve non-stop power and load, greatly improving the reliability of power supply. [0003] However, the number of distribution network equipment is large, the wiring form is becoming more and more complicated, and the transferable path of a single feeder is also increasing. In my country, the fee...
