Implementation of an Opening Resistor to Mitigate TRV in a Hydroelectric Project in the Peruvian Electrical System

In this hydroelectric generation project, connection is established in a 500 kV system, which includes series compensation. A comprehensive TRV analysis was conducted to evaluate the existing circuit breakers. Based on this analysis, it was determined that implementing opening resistors is necessary to mitigate the adverse effects of TRV and ensure compliance with Peruvian electrical regulations.
