Wind power master control cabinet heat management analysis and optimization method based on finite element method

Abstract

The invention discloses a wind power master control cabinet heat management analysis and optimization method based on a finite element method. The wind power master control cabinet heat management analysis and optimization method includes the steps of from a cabinet-top arrangement diagram, acquiring attributes of materials of a wind power master control cabinet and parameters of a circuit breaker and a relay inside the wind power master control cabinet; performing initial geometric modeling on the circuit breaker and the relay to obtain a three-dimensional model; subjecting the three-dimensional model to finite element meshing to obtain a finite element mesh model; acquiring design parameters of a heater and a fan; establishing a three-dimensional model for the wind power master control cabinet and fluid inside; performing hydro-mechanical meshing to obtain a flow field mesh model; restraining the flow field mesh model; determining physical parameters of the fluid in the flow field; calculating the temperature field and flow field of the flow field mesh model to obtain flow field analysis results; judging whether or not the flow field analysis results for the wind power master control cabinet meet industrial standards; if yes, ending; if not, optimizing a design scheme. The precise calculation results can be obtained with no need of building a solid model.

Description

technical field [0001] The invention relates to a thermal management analysis and optimization method for a main control cabinet of wind power based on a finite element method, and belongs to the technical field of wind power control. Background technique [0002] As non-renewable energy is facing the dilemma of depletion in the world, in order to meet the needs of industrial production and human life, people pay more and more attention to and utilize renewable energy such as solar energy and wind power. Among them, wind power generation is a relatively mature energy development technology. The main control system of wind power generation is the core component of the wind power generation system, so how to reasonably design the main control system of wind power generation has become one of the key points in the development process of wind power generation system. [0003] The wind power main control system usually includes a wind power main control system cabinet, circuit b...

Problems solved by technology

[0005] For theoretical research, ordinary calculations are only suitable for linear and simple geometric problems, and are limited by the ability of analytical methods to obtain accurate calculation results.

[0006] Although experimental research can obtain accurate calculation results, the premise is that a solid model needs to be manufactured, which is costly, time-consuming, and less flexible.
