为了吸收再生功率并降低列车的峰值输入功率，即平滑列车的输入功率，本文提出了一种基于频域的混合动力电动轨道车辆储能功率控制策略。通过使用干扰观测器应用损失补偿方法，在保持该控制器能力的同时提高了能量。然而，该损耗补偿方法需要超级电容器（SC）的精确电压-能量特性来估计正确的损耗。因此，SC的电容的非线性成为问题，因为它导致估计损耗的误差。因此，本文提出了一种方法来精确测量的SC的电压，电容的电压依赖性的能量特性。还提出了一种方法来实现这些特性的控制器。将该方法应用于控制器，并通过小规模实验系统验证了其有效性。© 2016日本电气工程师协会。出版社：John Wiley & Sons，Inc.
In order to absorb the regenerative power and to reduce the peak input power of a train—in other words, to smooth the input power of the train—in this paper we repot a frequency‐domain‐based power controlling strategy for energy storage of hybrid electric railway vehicles. Applying a loss‐compensating method by using a disturbance observer improves the energy while keeping ability of this controller. However, that loss compensating method requires precise voltage–energy characteristics of the supercapacitor (SC) to estimate the correct loss. Hence, nonlinearity of the capacitance of the SC becomes a problem because it causes an error in the estimated loss. Therefore, this paper presents a method to measure the voltage–energy characteristics precisely of the SC that has a voltage dependence on the capacitance. A method to implement those characteristics into controllers is also proposed. The loss compensating method is applied to a controller by using the proposed method, and its effectiveness is verified by a small‐scale experimental system. © 2016 Institute of Electrical Engineers of Japan.
