A real time security analysis software has been in service since May 1986. The software makes use of novel solutions for HV network operation problems. The architecture of the high level decision functions, the data base structure, the analytical functions (state estimation, observability, load-flow, contingency analysis) and the user friendly man/machine interface are described and discusseddata acquisitionload dispatchingpower system computer controlSCADA systemhigh level decision functionsEEF dispatching centerreal time security analysis softwareHV network operation problemsdata base structureanalytical functionsstate estimationobservabilityload-flowcontingency analysisuser friendly man/machine interfacetext::conference output::conference proceedings::conference paper
