| 摘 要： | 本文介绍了一种基于频率和电压下垂均流控制的无互联线并联UPS系统。由于采用有功和无功功率做为控制变量，从理论上分析了输出功率与两台UPS之间的输出电压的相位差和幅值差的关系，给出了系统的数字控制方案，在采用TMS320F240控制的两台3KVA的UPS上进行了实验，验证了理论分析。

| Abstract: | A load sharing control base on the frequency and voltage droop concept for parallel operation of two UPS system with no control interconnection lines is presented in this paper . Firstly , due to the use of active power and reactive power as control variables , the characteristics of output powers according to amplitude and phase differences between output voltages of two UPS system are analyzed . Secondly , the digital control algorithm is presented . Finally, experiments are presented to verify the theoretical discussion with two 3KVA UPS system employed TMS320F240 . |
