The main goal of is to increase the DA and ZSA setting estimates and selection efficiency, taking into account all types of protection relays constructive and algorithmic features of the mutual agreement procedure. To achieve this goal, the work is addressed in the following main objectives: (1) DA and ZSA settings estimation methodology for taking into account both power and power circuitry configurations, and substation primary schedule; (2) existing DA and ZSA settings selection methodology for assessment of different types of protection relays by mutual agreement application point of view; (3) new Methodology for DA and ZSA select settings and mutual coordination; (4) new methodologies proposed mathematical model, and they protective relay tripping speed setting mutual coordination of specialized software; (5) offers a new methodology for practical use case example.
