Problem Related To Designing And Computer-Aided Design For Air-Core Power Reactors

Air-core power reactor has been important equipment in power system at the present time. It starts later for developing air-core power reactor by ourselves in china, but also it is not high for automaticity of design and manufacture. The technique of computer-aided design is an important revolution in course of evolution for design and manufacture industry. From social development and requirement, it is utmost urgency for developing and applying of computer-aided design for air-core power reactor.Firstly, a careful analysis on basic technique about designing air-core power reactor is presented in the thesis. Several better mathematic models are summarized, including the formula of self-inductance and mutual inductance for two coils co-axially located, the formula of eddy current loss, the formula of magnetic field, and so on. The formulas used to calculate the mutual inductance between coils non-axially, and used to calculate electromagnetic force acted on air-core power reactor under the condition of power system short-circuit are also presented, it start from the basic principle of electromagnetic field. Secondly, the monolithic design method for single-phase air-core reactor and three-phase air-core reactor is considered. Based on these basic theories about design for air-core reactor, computer-aided design system for air-core power reactor is developed in Windows OS.It is the crucial task of this program that develops computer-aided design system for air-core reactor. To raise the applicability and development of the software, the industrial standard technique and that has extensive applicability is chose as far as possible in course of software development: develop independently from bottom layer with Windows as platform, and Visual C++ as development tool; develop a set of reasonable class hierarchy with object oriented method as guidance; make use of multiple threads technology to implement complex calculation; use database to realize resource sharing and data maintaining; choose OpenGL to draw andimplement visualization design of air-core reactor.Intelligent design of various air-core reactor can be completed by this computer-aided design system for air-core reactor, and engineering visualization analysis can be went on to design result, the various graph about information can be drawn, characteristic print form can be generated.
