Introduction: New Reflections on Ernesto Laclau's Theory of Populism
With the rapid development of high‐speed railway, the auto‐transformer traction network (ATN) is also expanding. However, due to the improved performance of electric multiple units (EMUs) and the non‐linear relationship between impedance and ground fault distance, distance protection has limited coverage and cannot accurately locate the fault distance by measuring impedance. This paper presents a model of the ATN considering the presence of EMUs, which effectively demonstrates the characteristics of current distribution under the ground faults. Furthermore, a ground fault identification method based on multi‐terminal currents is proposed to enhance the accuracy of fault identification and differentiate faults and EMUs. The mapping relationship between current distribution and fault location is derived, and an accurate fault location method is proposed. Compared to existing methods, this method is not affected by EMUs and AT parameters. The fault identification and location scheme for ATN employs multi‐terminal synchronous information. Finally, through simulation and experimental setups, case studies have been conducted to verify the accuracy and robustness of the proposed method in various fault scenarios. Certainly, this research has significant application prospects in fault analysis and detection for HSR.
In this article, we read the COVID-19 pandemic from a Lacanian perspective, in which trauma and ontological insecurity are at the heart of the analysis. Using a psychoanalytical approach allows us to grasp why the most common response to the pandemic consisted of intensified commitments to home, nationalism, and exclusionary bordering practices and, in effect, a return to geopolitical notions of “sovereignty.” This can be read in light of Lacan’s discussion of memory as a form of repetition, implying that any attempt to construe history in terms of a coherent narrative misses the unconscious, traumatic compulsion to repeat. In light of this, we consider populist responses to the pandemic as well as how the pandemic has worked as a “great unequalizer.” Such developments, we argue, must be read as representing a fragmentation of the national body and as heightening the vulnerabilities and asymmetric structures of power that inhere in what Lacan refers to as the symbolic order. Here, we propose that a postcolonial re-conceptualization of Lacan’s understanding of the mirror image and the Real is necessary if we wish to establish how the pandemic has reinforced existing patterns of abjectification and marginalization.
