N2 - In the industry, frequent load changes make the potential for short-circuit disturbances considerably. Therefore, an effective protection coordination system is required to secure the industrial equipment. A protective system must properly and securely reduce disturbances to avoid unexpected effects such as more severe equipment failures, power outages, and human safety risks. Protection coordination that integrates with another is necessary to create a more reliable protection system. The best protection has a structure that works quickly to secure disturbances so that they do not spread to other networks and has excellent coordination for identifying the types of disturbances. The leading benchmark for setting protection relays is TDS. The TDS (Time Dial Setting) parameter must be filled in while coordinating protection, especially in the overcurrent relay. TDS controls how long the relay operates for resolving a fault. The TDS value is typically calculated and analyzed to get the minimum TDS value. Despite this, considering the inrush current transformer. However, PT Petrokimia Gresik electricity system demonstrates the trial-and-error method of changing the curve until the CTI is used to obtain the correct TDS value in collaboration with other relays. An algorithm can be used to simplify and provide accurate TDS results. This final project will discuss calculating the TDS inverse time overcurrent relay with the Adaptive Modified Firefly Algorithm (AMFA) method on the electricity system at PT Petrokimia Gresik to get the minimum TDS value. This study used 2 typical with a radial system, and its network contains 3 transformers. If a disturbance occurs, this authorizes an inrush current to flow. Consequently, it is evaluated. The results of the study obtained the relay TDS value using the AMFA algorithm to get the optimum value below the specified maximum limit, considering inrush current.
