Maintain secure and reliable protection system performance amid the challenges arising from today’s changing electrical grids. Traditional approaches for ensuring sensitivity and coordination of protection elements lack the comprehensiveness and efficiency required to provide protection security on today’s complex and evolving power systems. Wide Area Protect Reviews (WAPR) are emerging to address the demands currently faced by protection engineers. Assessments across a wide area of the network that test the sensitivity of the different protection elements and assess the coordination of the protection system are proving effective. These protection security assessments test sensitivity against element-specific criteria and coordination, regardless of relay types and locations, throughout each stage of the fault clearing cycle. The automated simulation and the intelligent visualisation of results allows engineers responsible for the safe operation of the electric grid to efficiently perform periodic assessments and ensure the adequacy of protection system behaviour for credible contingencies and following system changes.
