Description

technical field [0001] The invention relates to the technical field of optimization design of power transformers, in particular to a multi-objective optimization design method for power transformers that integrates energy saving and noise reduction. Background technique [0002] With the development of the economy and the massive consumption of energy, the awareness of energy saving in society is getting higher and higher. At present, the power transformers that are widely used in my country have a total annual power loss of about 250 billion kW·h, which is equivalent to the sum of the power consumption of three medium-sized provinces. It can be seen that the energy-saving design of power transformers is of great significance. [0003] In addition, with the rapid growth and gradual concentration of my country's electricity load, power transformers are required to go deep into the load center to reduce the power supply radius, which makes more and more power transformers appe...

Problems solved by technology

[0005] However, in the above studies, the research on energy saving and noise reduction of power transformers is still in progress independently, and with the rapid development of the current era and the ever-changing social needs, new requirements have been put forward for this, so there are It is necessary to find a new method that takes into account both energy saving and noise reduction of power transformers; in addition, the optimal design of transformers is still in the 1990s, and has not fully utilized. With the increasing development of computer and information technology And the new technology and new achievements produced, the optimal design of this transformer still needs to be further improved
