High-frequency high-voltage transformer design optimization method based on genetic algorithm

Abstract

The invention discloses a high-frequency high-voltage transformer design optimization method based on a genetic algorithm. On the basis of a minimum loss formula of a transformer and the insulation dimension and the iron core shape of the transformer, a mathematical model is established, a genetic algorithm is adopted for optimizing the transformer by taking the number of turns of primary sides and the layer number of secondary sides as optimization variables and taking efficiency as an optimization target, so that the efficiency of the transformer is maximized, the loss of the transformer is minimized, temperature rise is minimized under an equal condition, the leakage inductance and the distribution capacitance of the transformer are fully utilized to participate in the work of a power system to form an LCC (Life Cycle Costs) resonance circuit, and the loss of the transformer is reduced so as to lower the temperature rise. Compared with the prior art, the invention introduces the genetic algorithm, the genetic algorithm exhibits a problem non-relevant quick and random search capability, searches by starting from a group and has the characteristic of concurrency, and a plurality of individuals can be simultaneously compared to greatly quicken optimal solution search speed.

Problems solved by technology

[0003] The high-frequency transformer is the core component of the entire electrostatic precipitator power supply, but abnormal situations such as high temperature of the transformer and untimely heat dissipation often occur, especially the characteristics of the high-frequency transformer are much different from those of the power frequency transformer with the high frequency of the input. Different, too high temperature will not only affect the insulation life of the transformer, seriously even affect the stable operation of the power grid, and bring unnecessary losses to people's production and life, so the temperature of the high-frequency high-voltage transformer must be controlled within a reasonable range
