【摘要】：福岛核事故发生后,核电安全和发展问题引起关注。我国核电发展受到了很大的影响:“积极发展”的方针被“安全第一”所取代。从电气设计的角度研究并采取积极的预防与缓解措施,提高核电站整体安全水平,对推进我国核电事业安全高效地发展具有积极的现实意义。本文以国内在建或已建的M310、WWER1000、AP1000堆型核电站为研究对象,阐述了厂用电系统的设计要求和厂用电源配置原则。对各堆型厂用负荷的分类方法进行对比,总结了厂用负荷分类的原则。根据厂用负荷供电要求,本文将厂用电系统分为正常厂用电系统和应急厂用电系统。对各堆型正常厂用电系统电源引接方式、系统接线、分段原则、电压等级选择以及厂用电源切换方式进行了分析研究,并对应急厂用电系统的组成及配置进行了探讨。在总结归纳国内在建和已建核电厂厂用电设计方案的基础上,提出了发展方向和建议,以期对核电厂厂用电设计人员提供技术支持。由于M310、WWER1000、AP1000核电站设计主要参照国外标准,受多国技术影响,国内核电标准技术路线不统一,厂用电系统设计方案存在差异。编制适合我国国情的核电厂厂用电设计技术规范是必不可少的工作,只有建立适合我国工业基础的核电标准体系,才能实现真正意义上的核电自主化。希望本文对核电厂厂用电设计方案的分析研究能够为我国核电标准体系的建立提供参考和借鉴。
[Abstract]:After the Fukushima nuclear accident, nuclear power safety and development issues have aroused concern. The development of nuclear power in China has been greatly affected: the policy of "positive development" has been replaced by "safety first". From the point of view of electrical design, it is of positive practical significance to study and take active preventive and mitigation measures to improve the overall safety level of nuclear power plants and to promote the safe and efficient development of nuclear power industry in China. This paper deals with the design requirements of the power supply system and the principle of the configuration of the power supply for the domestic nuclear power station M310, WWER1000, AP1000, which is under construction or has been built. This paper compares the classification methods of each type of plant load and summarizes the principle of plant load classification. According to the requirement of power supply, this paper divides the power supply system into normal power supply system and emergency power supply system. This paper analyzes and studies the power source lead mode, system wiring, segmental principle, voltage grade selection and power switching mode of each stacked normal auxiliary power system, and probes into the composition and configuration of emergency auxiliary power system. On the basis of summing up and summing up the design scheme of domestic and existing nuclear power plants, the development direction and suggestions are put forward in order to provide technical support for the design staff of nuclear power plants. Because the design of M310 / WWER1000 / AP1000 nuclear power station mainly refers to foreign standards, it is influenced by many countries' technology, and the technical route of domestic nuclear power standard is not uniform, and the design scheme of power supply system is different. It is necessary to compile the technical specification for the design of the auxiliary power of nuclear power plant suitable for the national conditions of our country. Only by establishing the standard system of nuclear power which is suitable for the industrial foundation of our country can we realize the real sense of nuclear power autonomy. It is hoped that the analysis and study of the design scheme of power plant in this paper can provide a reference for the establishment of the nuclear power standard system in China.
