The tool for calculation of relay settings for power plants

• Calculation of all settings for all protection schemes of power plant units
• Calculation of all settings for power plant main and auxiliary transformer relays

The setting of all protection relays in the power plant calculated regarding to power network structure and also methods prepared by IEEE and NERC and related studies approved by Iranian Grid Management Company (IGMC). Generator unit protection, Main and auxiliary transformer protection settings coordinated to the relays of power transmission network.

DPAT also prepared a tool for relay setting evaluation that can verify the settings using simulation of the events that the relay must be operated/not operated:

• Simulation of various faults in different operational states for power plant and transmission grid
• Time domain/dynamic simulation
