cape overview

The traditional approaches for studying coordination between pairs of protection elements on a project by project basis are inadequate for ensuring the reliable operation of today’s power systems with their increasing complexity and dynamic nature.

The Computer Aided Protection Engineering software (CAPE), is a comprehensive protection simulation tool with unprecedented capabilities arising from its;

  • – detailed network modelling and comprehensive protection system representation incorporating the design complexity inherent to the utilization of multifunctional numerical protective devices,
  • – superior short circuit algorithms, comprehensive fault study automation capabilities and a sophisticated time stepped analysis to investigate protection system performance throughout the entire fault clearing cycle,
  • – advanced data management features, offering new levels of data integrity with support for CIM XML compliant databases for network topology model management and protection data exchange and a Neutral interface exchange for relay setting data transfer with third party products
  • – ability to interact with complementing mainstream software tools such as transient stability and electromagnetic transient applications.

With CAPE comprehensive assessments considering the complete protection scheme and its performance throughout the entire fault clearing cycle, based on up-to-date network and protection data extracted from high integrity enterprise information systems, can now be undertaken to provide regular systematic protection security assessments across wide network areas with various operating conditions to meet the demands of modern power systems.
