A working method of an intelligent switching device for transformers used in residential quarters powered by dual power supplies

Abstract

The invention discloses an intelligent transformer switching device for a dual power supply community and a working method of the intelligent transformer switching device for the dual power supply community. The intelligent transformer switching device comprises a synchronous real-time first-transformer data collecting system, a synchronous real-time second-transformer data collecting system and a transformer running mode control decision-making system. The transformer running mode control decision-making system comprises a first transformer working condition database, a first transformer working condition analysis unit, a second transformer working condition database, a second transformer working condition analysis unit, a community load prediction module and a community optimal running mode analysis unit, wherein the first transformer working condition database is firstly connected with the synchronous real-time first-transformer data collecting system and then connected with the first transformer working condition analysis unit, the second transformer working condition database is firstly connected with the synchronous real-time second-transformer data collecting system and then connected with the second transformer working condition analysis unit, and the community load prediction module is firstly connected with a community history load database and then connected with the community optimal running mode analysis unit. The intelligent transformer switching device is high in accuracy, high in reliability, good in stability and remarkable in energy-saving effect, multiple wireless interfaces are formed, and the technical requirements of a smart power grid are met.

Description

technical field [0001] The invention relates to the technical field of transformer control, in particular to an intelligent switching device for a transformer used in a residential area powered by dual power supplies and a working method thereof. Background technique [0002] At present, in the power supply and distribution system of residential quarters, there are generally problems such as a large number of transformers at the distribution end, large losses, low degree of automation, and heavy operation and maintenance workload. In most parts of our country, the temperature changes greatly in four seasons. In summer and winter, distribution transformers are basically in full-load operation state, while in spring and autumn, many distribution transformers are in low-load operation state. Especially for the newly put into operation of the distribution substation, the capacity design margin of the transformer is relatively large, resulting in an increase in active power loss....

AI Technical Summary

Problems solved by technology

[0004] However, there is no research on the optimal intelligent switching method for community transformers at home and abroad. When the transformer in the community is faulty or defective, it will cause power outages for users.
