Power System Stability Analysis

What this covers

• Transient stability — generator rotor angle and machine synchronism following faults and switching events.
• Critical clearing time — the maximum fault duration the system can survive, which feeds directly back into protection settings.
• Voltage stability — recovery behaviour and the risk of voltage collapse under heavy loading.
• Motor reacceleration — whether motor loads recover after a fault or stall and must be shed.
• Islanding and load shedding — behaviour on separation from the grid, and the load shedding scheme needed to survive it.
• Frequency response — governor and generator response to load and generation imbalance.

What you receive

• Stability study report covering each contingency assessed
• Time-domain simulation results for rotor angle, voltage and frequency
• Critical clearing times with protection implications identified
• Load shedding scheme recommendations where required
