PRINCIPLES OF AUTOMATION OF THE CONTROL OF OPERATIONAL RELIABILITY OF ELECTRICAL NETWORK
We systemize concepts and ideas underlying the automation of the control of operational reliability of electrical networks. Flow security and technological reliability are analyzed as the components of operational reliability. Degree of flow security is considered as the value of its “stock” formed by a set of acting “degrees of protection”. We propose a generalization of the N - k security criterion to express the opportunities for rapid flow recovery after k failures. Also we introduce the notion of technological reliability of operations for the study of conditions of personnel safety and equipment security at the performance of operation. It is shown that automation of flow monitoring and enforcement and technological reliability in operational dispatch management system of power grid should be based on a system of formalized locking rules. These rules check the action of the “degrees of protection” of the flow and operations.
