Abstract

The dynamic and steady-state behaviors of distributed power supply in a DC architecture with a minimized DC bus capacitor is investigated in this paper using the power balance control technique. The circuit is simulated and analyzed using MATLAB Simulink. The proposed system significantly improves the dynamic response of the converter to load steps with the minimized DC bus capacitor for a distributed Power System. The possibility of using a ratio of capacitance/watt lower than the typical values used in commercial applications, while maintaining the output voltage regulation, is theoretically proved. The minimized DC bus capacitors of the proposed system are 100µF (0.1µF/W), 400µF (0.47µF/W), 80µF (0.53µF/W), 100µF (0.67µF/W), 2000µF (5µF/W) and 2000µF (5µF/W) for the 380Vdc, 100Vdc, 60Vdc, 48Vdc, 24Vdc, and 12Vdc, respectively. The simulation results show the following advantages: small capacitor size, reduced converter volume, good steady-state behavior, and fast dynamic transient response.

最小直流母线电容的直流结构下分布式电源的动态和稳态特性

本文采用功率平衡控制技术，研究了最小直流母线电容的直流结构下分布式电源的动态和稳态特性。利用MATLAB Simulink对该电路进行了仿真和分析。该系统以最小的直流母线电容显著改善了分布式电力系统变换器对负载阶跃的动态响应。理论上证明，在保持输出电压调节的同时，使用比商业应用中使用的典型值更低的电容/瓦比的可能性。该系统的直流母线最小电容分别为100µF(0.1µF/W)、400µF(0.47µF/W)、80µF(0.53µF/W)、100µF(0.67µF/W)、2000µF(5µF/W)和2000µF(5µF/W)，适用于380Vdc、100Vdc、60Vdc、48Vdc、24Vdc和12Vdc。仿真结果表明，该方法具有电容器体积小、变换器体积小、稳态性能好、动态瞬态响应快等优点。
