TRANSMISSION LINE PROTECTIVE SYSTEMS LOADABILITY

摘要

This paper is about the effects of protective relaying on the loadability of transmission lines. The calculation of relaying load limits for use in comparing to transmission line load limits or other limits is discussed. The identification of problems associated with the application of relay protection that result in the interference of line loading capabilities is covered. This is followed by the discussion of methods available that are aimed at increasing the loadability of relay schemes while also maintaining required levels of relay coverage and security.
