Analysis of Overvoltage and Undervoltage Protection Response Under STATCOM Malfunction Scenarios

Year: 2026

Type: conference-paper

Abstract: The integration of STATCOM devices in transmission systems enhances voltage stability and overall power system performance. However, under abnormal operating conditions, STATCOM malfunctions may affect the behavior of protection schemes. This paper investigates the response of overvoltage and undervoltage protection under different STATCOM malfunction scenarios. The study is conducted using MATLAB Simulink simulations, considering various disturbance conditions combined with several types of STATCOM operational anomalies, including delayed response, insufficient compensation, and incorrect reactive power injection. The results show that STATCOM malfunctions can distort voltage profiles, leading to incorrect relay operation. The impact varies depending on both the disturbance type and the malfunction scenario. These findings highlight the importance of proper coordination between STATCOM control systems and protection settings to ensure reliable and secure power system operation.
