摘要
Abstract
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.关键词
