摘要
基于实时数字仿真器的硬件在环(HIL)仿真技术在电力系统、电动汽车、航空航天等领域得到了广泛应用。目前关于HIL仿真技术的研究主要集中在仿真模型元件的准确性研究,而数字仿真的延时确定方法鲜有报道,这会影响到全局仿真结果。这里以高压直流(HVDC)输电仿真模型为例,分析HIL仿真时延产生机理,提出一种基于数学模型的HIL仿真时延预测补偿方法,通过提取被控对象的典型数学模型,并在控制设备中建立该被控对象数学模型,调节仿真时延直至稳态或瞬态仿真试验中仿真模型和控制设备得到的物理量相同。仿真试验通过HVDC输电系统的直流电压和无功功率两个数学模型来验证该方法的有效性。
Hardware-in-loop(HIL)simulation technology based on real-time digital simulator has been widely used in the power system,electric vehicle,aerospace and other fields.The accuracy of the physical components model is mainly focused on the HIL simulation technology.However,the method to determine the time delay of the simulation is rarely reported,which will affect the overall situation.The time delay of an high voltage direct current(HVDC)transmission HIL simulation model is analyzed.Then a time delay prediction and compensation method based on a mathematical model in the HIL simulation is proposed.By extracting the typical mathematical model of the controlled object and establishing its mathematical model in the control device,the simulation time delay is adjusted until the steady state or the transient simulation test has the same physical quantity obtained by the simulation model and the control device.The proposed method is verified by the direct current voltage model and reactive power model of the HVDC transmission system in the simulation test.
