SynchroGrid's engineers further contribute to the system protection industry by publishing and presenting papers at the major relay conferences in the United States, including the Texas A&M, Georgia Tech, and Western Protective conferences.
SynchoGrid's publications focus on relay applications, fault analysis of events, and research results. Look below to see a few of the conference papers that we have presented recently.

Unique expertise will be crucial in putting together a process which power plant owners can easily implement and apply to meet the requirements for PRC-027-1. This is where automation tools like Settings Automation Relay Assistant (SARA) can help by streamlining the entire relay setting development process.

C. Thomas, J. Perez, L. Hankins and H. Tribur, "An innovative and automated solution for NERC PRC-027-1 compliance," 2018 71st Annual Conference for Protective Relay Engineers (CPRE), College Station, TX, USA, 2018, pp. 1-11.
Compliance with NERC PRC-027-1 has brought increasing stress to utilities as they work to establish a defined process for performing relay setting development and coordination at regular intervals. While current software programs attempt to aid utilities in complying with this new standard, they only offer an overwhelming and unmanageable report of coordination study results. None of the current programs provides a work flow from relay setting development to wide area coordination, which is what utilities desperately need. In this paper, we present an innovative process to comply with the R1, R2, and R3 requirements of PRC-027-1 through the use of an automated solution.

This paper demonstrates a sophisticated solution that introduces engineers to an improved and more efficient relay setting development process. Using the latest software development tools, this new solution provides a more advanced method to calculate settings compared to existing methods, and provides an intelligent way to uniformly standardize relay setting templates, eliminate data transfer errors, and overall perform settings, peer-peer review processes and coordination studies at a fraction of the previous time.

In partnership with Cross Texas Transmission, this paper discusses the operation of two differential relays protection algorithms during a reactor inrush. Detail algorithm and waveform analysis of the Restrain and Operate current reveal the fundamental differences between the two relays.

This paper discusses the two forms of logic scheming: Load Encroachment Setting and Out-of-Step Logic scheming. These are presented as they are applied to long transmission lines, where it can be difficult if not impossible to apply both settings at the same time.

This paper focuses on the effects of subharmonics in the power system. This is predominantly observed when a series line capacitor is used in transmission lines to increase power transfer from wind farms.
