Application and Integration of Automation-Based Tools for Efficient and Accurate Modeling of Transmission System Protection

The protection simulation capabilities of short-circuit software platforms can offer significant efficiency benefits for utilities facing increased responsibilities due to emerging compliance requirements. However, the challenges of modeling an entire system of protection as well as the need to keep it updated have limited the practical utilization of these simulation capabilities. Automation-based tools offer a solution to these modeling challenges, enabling efficient and accurate creation of protection representation on these short-circuit platforms. This paper presents the experiences and technical considerations of four utilities that have employed these automation-based protection modeling methodologies. First, implementation and deployment considerations are discussed, in order to meet the specific needs and conventions of an organization in engineering, data, and logistical aspects. Next, actual utilization of the tools and their impact on protection activities are explored. Third, strategies for long-term governance are considered, covering the utility processes necessary to maintain the tools. Finally, general experiences and thoughts are provided by the four utilities, as well as potential avenues for expansion of this engineering automation concept, and to further assist Protection and Control departments in meeting the challenges of the modern power systems industry.
