Abstract

The invention discloses an intelligent estimation system for transformer capacity. The system comprises an acquisition unit used for acquiring the standard information of transformer capacity estimation, a conversion unit used for converting the standard information into the limiting condition information, a detection unit which is used for detecting easy influence factors of a transformer, including the transformer height, the transformer temperature, the transformer insulation performance, the transformer phase number and the transformer cooling level, and a comparison unit used for calculating the capacity of the transformer and comparing the capacity with a standard recommended impedance minimum value. The system is advantaged in that a technical problem of low efficiency caused by manual operation according to experience in the prior art is solved, system design is reasonable, and transformer capacity estimation efficiency is improved.

Description

technical field [0001] The invention relates to the field of power system research, in particular to an intelligent estimation system for transformer capacity. Background technique [0002] The rated capacity of the transformer refers to the customary value of the apparent power under the main tap. The capacity specified on the transformer nameplate is the rated capacity, which means that the tap changer is located in the main tap, which is the product of the rated full-load voltage, rated current and the corresponding phase coefficient. For three-phase transformers, the rated total capacity is equal to = 3 × rated phase voltage × phase current, and the rated capacity is generally expressed in kVA or MVA. The rated capacity is the maximum capacity that can be continuously output during the specified normal service life, such as 30 years. The actual output capacity is the product of the voltage when there is load (when the load is inductive, the voltage is less than the rat...
