随着分布式发电技术的不断发展,将分布式发电供能系统以微电网的形式运行,与大电网互为支撑,成为发挥分布式发电供能系统能效的最有效方式之一。航天电力系统由于具有较强的分布式特点,而其对供电可靠性要求高,适合采用微电网系统。在归纳总结微电源模型的基础上,分别在独立运行和并网运行时分析了微电源逆变器的控制特性,根据不同微电源的类型分别采用PQ控制和V/f控制策略,提出了相应的控制器设计方法,建立了微电网模型。试验结果表明,微电网技术适合在航天供电系统中应用发展。
With the continuous development of distributed generation technology, it is one of the most effective ways to utilize distributed generation and power supply system in the form of microgrid and support each other with large power grid. Aerospace power system because of its strong distributed features, which require high reliability of power supply, suitable for the use of micro-grid system. On the basis of inducting and summarizing the micro-power model, the control characteristics of the micro-power inverter are analyzed respectively in independent operation and grid-connected operation. According to different types of micro-power supply, PQ control and V / f control strategy are respectively adopted, The controller design method, the establishment of a micro-grid model. The test results show that microgrid technology is suitable for the application development in space power supply system.
