Abstract

Hospitals become public service buildings that bring together various individuals with diverse characteristics. Therefore, the activities that occur in it will produce various kinds of stigmas or points of view from its users depending on how and from what point of view they see and interpret the activities. This study aims to explore how user behavior settings are formed in a physical setting in a hospital using a phenomenological approach that is presented in a narrative manner. The results of the study using case samples involving childbirth activities concluded that the use of the phenomenological method is very supportive in exploring how users interpret their experiences that occur in a subject in a physical setting until it ultimately affects their stigma or psychology.

Abstract

The integration of wind power plants into Indonesia’s electrical grid requires a high level of operational reliability, particularly during network disturbances that trigger temporary voltage dips. Low Voltage Ride Through (LVRT) conditions pose a major challenge, as they can induce transient instability in the generator and potentially lead to turbine disconnection from the grid. This study aims to evaluate the transient stability of a wind turbine generator during grid disturbances by analyzing the current response in the d and q axes, which serves as a key dynamic indicator within the wind energy conversion system. To enhance the turbine's ability to remain connected during LVRT events, a STATCOM controlled by a Linear Quadratic Regulator (LQR) is employed to provide rapid and adaptive reactive power compensation. Simulations are conducted to observe the oscillation patterns, damping behavior, and steady-state conditions of both current components following the disturbance. The results demonstrate that the d–q axis currents exhibit well-damped oscillations, return smoothly to steady-state values, and show no signs of divergence. These findings confirm that the LQR-controlled STATCOM significantly improves transient stability, enhances the operational reliability of wind power plants, and supports the safer and more sustainable integration of renewable energy into the electrical grid.
