【摘要】 为了满足含多种分布式电源直流微电网运行和控制策略的测试需求,研究了一种针对直流微电网的多层次、多时间尺度硬件在环仿真(HILS)系统。所设计方案中,直流微电网的一次调压、二次调压和优化运行控制算法分别在不同的实时仿真机和控制器中实现,且兼顾了本地重点单元控制算法的验证。最后,搭建了由控制器DSP,RT-LAB实时仿真机、c RIO实时处理器及上位机等组成的HILS测试平台,并通过算例验证了HILS系统平台的灵活性和可靠性。更多还原

【Abstract】 A multi-level and multi-time-scale hardware in-the-loop simulation(HILS)system as a new method was proposed to develop and test the control algorithms and operation strategies for the DC microgrid.Primary control,secondary control and tertiary control were implemented in different simulators and controllers.The key unit and system control methods could be both tested in the proposed design.Finally,the proposed HILS platform in-cluding a RT-LAB for real-time simulation,an actual controller under test,a cRIO for coordination control and the host computer was built according to the proposed design and different processors computing ability and characteristics.Detailed tests were carried out to show flexibility and reliability of the proposed HILS platform.更多还原
