【摘要】：福岛核事故让我们更加清晰的认识到,提高核电厂输配电系统和厂用电系统的安全性和可靠性是提高核安全标准的重要措施之一。反应堆停堆余热的存在,是核电厂与火电厂很重要的区别,也对厂用电提出了比火电厂更为严格的要求。核电站必须要保证事故状态下的能够将反应堆余热安全导出,保证一回路冷却剂系统不发生超温超压,以保证一回路压力边界的完整性。本文简述了核电厂与火电厂的区别以及核电厂厂用电设计的研究现状。介绍了高温气冷堆核电技术及示范电站的概况。以高温气冷堆核电站示范工程为例,分析了电气主接线和厂用电接线的设计方案及设计依据,按照国家标准和技术规范对发电机、主变压器、高压厂用变压器、辅助变压器、发电机出口断路器、离相母线等关键设备的参数进行了计算。本文亦对220kV和110kV GIS的设计进行了详细的研究。文章的最后介绍了电厂防雷的设计。
[Abstract]:The Fukushima accident has made us realize that improving the safety and reliability of power transmission and distribution systems is one of the most important measures to improve nuclear safety standards. The existence of residual heat in reactor shutdown is an important difference between nuclear power plant and thermal power plant. In order to ensure the integrity of the pressure boundary of the primary circuit, the nuclear power plant must ensure that the residual heat of the reactor can be safely derived under the accident condition, and that the coolant system of the primary circuit will not be overheated and overpressurized in order to ensure the integrity of the pressure boundary of the primary circuit. In this paper, the difference between nuclear power plant and thermal power plant and the research status of the design of nuclear power plant are briefly described. The nuclear power technology of high temperature gas cooled reactor (HTGR) and the general situation of demonstration power station are introduced. Taking the demonstration project of high temperature gas cooled reactor nuclear power station as an example, this paper analyzes the design scheme and design basis of the main electrical wiring and the auxiliary electric wiring. According to the national standards and technical specifications, the generators, main transformers, high voltage power transformers and auxiliary transformers are analyzed. The parameters of key equipment such as generator outlet circuit breaker and off-phase bus are calculated. This paper also studies the design of 220kV and 110kV GIS in detail. Finally, the design of lightning protection in power plant is introduced.
