An improved algorithm for phase-based voltage dip classification
… algorithms. The new algorithm computes the dip type based on the difference in phase angle between the measured voltages.

Models for Calculating Voltage Dip Caused by Induction Motor Starting.
… upon starting. For this condition, the terminal voltage will dip for other motors throughout the network. Because the torque is related to voltage squared, significant performance deterioration can occur at remote motor load locations.In an existing plant, a voltage dip study can isolate problem …

Intelligent voltage dip mitigation in power networks with distributed generation
… and utilization system that experiences any voltage, current or frequency deviation from normal operation. In the current power and energy scenario, voltage-related PQ disturbances like voltage dips are a fact which cannot be eliminated from electrical power systems since electrical faults, …

Comparison of low voltage ride through capabilities of synchronous generator with STATCOM and DFIG based wind farms
… fault ride-through capabilities, providing voltage control and power quality improvement etc. The goal of a Fault Ride Through (FRT) or Low Voltage Ride Through (LVRT) system is to enable a wind farm (WF) to withstand a severe voltage dip at the connection point and still stay connected to …

Synchronous generator and excitation system response to GIC
… increased non-active power demand and potential voltage collapse. While most power system studies have focussed on the transformer's response to GIC, there has been very little research investigating the response of synchronous generators and excitation systems to such disturbances. Moreover, …

Design and model: Intelligent solid-state current limiter to prevent sympathetic tripping problem on power and energy applications
… reveal that transferring power near the system voltage stability limit is a major cause of the Sympathetic Tripping Problem. Limiting fault current and using synchronous condensers for reactive power support were shown to solve the Sympathetic Tripping Problem.
