摘　　要：为提高重要负荷的供电可靠性和供电质量,同时降低可靠供电岛的实现成本,本文首先给出了基于多变流器和高速电子开关的可靠供电岛拓扑结构。其次,根据变流器的端口特性设计了系统层面的控制策略,进一步设计了变换器层面的控制策略以实现各变换器端口特定的运行模式。分析表明,所提控制策略在可靠供电岛运行于不同工况时控制模式无需切换,仅需设定不同的指令量。最后,在Matlab/Simulink中基于所提控制策略仿真验证了可靠供电岛在实现高可靠供电方面的有效性,进一步表明了高速电子开关的采用不但简化了装置的结构和控制策略,降低了实现成本,也最大限度地保证了对负荷供电的高可靠性。To improve the reliability and quality of power supply for important loads while lowering the implementation cost of reliable power supply island ( RPSI ), the topology of RPSI is firstly presented based on multiple inverters and high-speed electronic switches. Secondly , the control strategies on the system level are designed according to the port characteristics of inverters. Besides , the control strategies on the inverter level are further designed so as to realize the specific operation modes of inverter ports. Theoretical analysis shows that the proposed control strategies just need to configure different values of command quantity without switching the control mode when RPSI operates in different work-ing conditions. Finally , based on the control strategies , the effectiveness of RPSI in realizing the high reliability of pow-er supply is verified in Matlab/Simulink , which further proves that the adoption of high-speed electronic switches can not only simplify the structure and control strategy of RPSI and thus reduce its implementation cost , but also guarantee the high reliability of power supply for loads to a maximum extent.
