Maximizing the Energy Output of Soft Electrohydraulic Generators. [PDF]

Adv Sci (Weinh)
Many energy resources cannot be viably harvested with electromagnetic generators. This article evaluates the potential of soft electrohydraulic generators as an alternative approach for energy capture. An analytical model charts their operational limits and a rigorous experimental study results in new performance benchmarks with maximum specific energy

Voltage Stability Analysis of Power System with Photovoltaic Power Plant

Jurnal Nasional Teknik Elektro, 2023
Photovoltaic power plants usually do not provide reactive power output; hence the application of large photovoltaics in power systems will decrease the voltage stability level of the power system. Capacitor banks can provide reactive power to compensate

Application of Magnitude and Phase Angle to Boundary Area-Based Algorithm for Unbalance Relay Protection Scheme in 115-kV Capacitor Bank

IEEE Access, 2021
Identification of fault locations in capacitor banks is still under development. Although, faults in capacitor banks can be detected by an unbalance relay, it cannot identify the fault location.

Behaviour analysis of H‐bridge high‐voltage capacitor banks fault on 230‐kV substation using discrete wavelet transform

IET Generation, Transmission & Distribution, 2023
The protection of traditional high‐voltage capacitor banks relies on an unbalance relay which operates when an internal fuse is blown. However, the unbalance relay cannot indicate the cause of the fault.
