Intelligent comprehensive control method for distribution transformers

Abstract

The invention discloses an intelligent comprehensive control method for distribution transformers, belonging to the field of automatic control of electric systems. The intelligent comprehensive control method comprises the concrete steps of: automatically detecting rated capacities of the transformers by the systems; respectively detecting; when the rated capacity A of the transformer T1 is equal to, more than or less than B, calculating load values of the transformers in real time by distribution monitoring devices; and delaying for a time of delta t, if the condition is still met, determining the transformer which meets the rated capacity to supply power. Compared with the prior art, various running modes of the transformers can be realized according to the load situations, so that the losses of the transformers are reduced to the maximum extent, and the aim of economic running of the transformers is achieved; in addition, when the high-level power faults of the distribution transformers are caused or after the high-level power faults are removed, the intelligent comprehensive control method realizes an automatic power restoration function according to the actual running situation.

Description

technical field [0001] The invention relates to an intelligent comprehensive control method for distribution transformers, in particular to an intelligent comprehensive control method for economical operation of a 10kV distribution transformer, which belongs to the field of automatic control of electric power systems. Background technique [0002] The load of a large number of existing power distribution rooms changes greatly, and the operation mode is difficult to determine. When the upper-level power supply of the distribution transformer fails, it will affect the power supply of low-voltage users, or after the upper-level fault is eliminated and the power supply is restored, the low-voltage cannot automatically restore power supply and many other reasons. The power distribution room with dual transformers installed in China is manually controlled whether it is in single-transformer operation, parallel operation or separate operation, and it is impossible to realize the aut...

[0002] The load of a large number of existing power distribution rooms changes greatly, and the operation mode is difficult to determine. When the upper-level power supply of the distribution transformer fails, it will affect the power supply of low-voltage users, or after the upper-level fault is eliminated and the power supply is restored, the low-voltage cannot automatically restore power supply and many other reasons.

The power distribution room with double transformers installed in China is manually controlled whether it is in single-transformer operation, parallel operation or separate operation, and it is impossible to realize the automatic and economical operation of the transformer according to the change of load.
