Automated Modeling of Power System Protective Devices for Advanced Analysis of Protection System Performance

This paper presents automation-based approaches and tools for modeling of complex protection functions in modern power systems. The paper discusses the process steps and challenges related to data gathering, aligning primary network data and protection data, handling device settings from different vendors, and accurately modeling complex functions such as telecommunication schemes. The paper also discusses the processes that can be utilized for integration of automation with the legacy setting management procedure. The process for data and operational quality assurance of various protection elements is also presented and discussed. The presented modeling approaches and tools have been successfully utilized in several large-scale projects. Accordingly, the efficacy and feasibility of the proposed approaches in real-world projects are discussed.
