摘　　要：传统的分布式中频供电系统所占空间大,维修保养困难。针对这些缺点,研究了集中式中频供电系统,并就其可行性进行了论证。选取生命力和可靠性作为中频供电系统的主要评估指标,参照工频主电网给出了集中式供电的中频电网设计方案。利用一种考虑电气设备三维位置信息的生命力评估算法,统计出两种中频供电系统的生命力指标。在工频电网正常工作的前提下,利用故障树分析法,对两种中频供电系统的可靠性进行了对比与分析。结果表明:相对于传统的独立式中频供电系统,集中式中频供电系统在生命力和可靠性方面有较大提高。Conventional power supply system with frequency of 400Hz is dispersing and independent,so it occupies much space and its maintenance is difficult.Considering these deficiencies,a centralized power supply system with frequency of 400Hz is analyzed and the feasibility of the scheme is discussed in the paper.The major criteria of the evaluation used in the analysis are survivability and reliability.The design scheme of centralized supply power system with frequency of 400Hz is given.The method,in which three-dimensional information of the loading is taken into consideration,is used to calculate survivable indexes for two power systems.Reliability of these two systems is analyzed by FTA.Research results show that compared with the conventional power supply system,centralized power system with frequency of 400Hz has made greater progress with respect to survivability and reliability.
