【摘要】：在石化能源资源量日益减少的现代社会,核电这种绿色能源因不受地理位置、气候环境等的影响得到了强势发展。我国已明确提出引进、吸收发展三代核电技术;而核电主泵变频器的研制是三代核电关键设备国产化的重要组成部分;本文以大型先进压水堆核电站用主冷却剂泵变频器为对象,围绕其可靠性设计问题进行了研究和开发工作。论文的主要工作如下:(1)研究了国内外高压大容量变频器主电路拓扑结构,提出核电主泵变频器电气主回路拓扑结构采用H桥级联方案;(2)依据设备现场运行数据,进行可靠性分析,根据得出系统可靠性分配方案进行系统设计;(3)根据设备需求提出电子电气产品器件选型,进行硬件电路设计,提出软件架构。(4)根据设备需求完成了功率单元设计,按照功率单元实验大纲进行了功率单元型式实验验证;(5)按照设备测试大纲进行了整机型式实验验证设计方案的可行性。该系统在现已完成了样机的型式试验和电磁兼容试验,通过了国家技术委员会组织的科技成果鉴定。
[Abstract]:In the modern society where the amount of fossil energy resources is decreasing day by day, the green energy of nuclear power has been developed strongly because of the influence of geographical location, climate environment and so on. China has clearly proposed to introduce and absorb and develop the third generation of nuclear power technology, and the development of the main pump converter of nuclear power is an important part of the localization of the key equipment of the third generation of nuclear power. In this paper, the main coolant pump inverter for large advanced PWR nuclear power station is studied and developed around its reliability design. The main work of this paper is as follows: (1) the main circuit topology of high voltage and large capacity inverter at home and abroad is studied, and the H bridge cascade scheme is used in the topology structure of the main circuit of nuclear power main pump converter. According to the reliability analysis, according to the system reliability distribution scheme, the system design is made. According to the equipment requirement, the electronic and electrical products are selected, and the hardware circuit is designed. Software architecture. 4) the power unit design is completed according to the equipment requirement, and the power unit type experimental verification is carried out according to the power unit experimental outline. 5) the feasibility of the design scheme is verified by the whole machine type experiment according to the equipment test outline. The system has now completed the type test and electromagnetic compatibility test of the prototype, and has passed the scientific and technological achievements appraisal organized by the National Technical Commission.
