FUZZY MODELING OF SWITCHING EQUIPMENT FOR TASKS OF ASSESSING THE RISK OF EMERGENCY SITUATIONS IN THE EPS IN CASE OF ELECTRICAL EQUIPMENT FAILURES

Today in the electric power industry of Ukraine issue assessing risk EPS operation due to failures electrical equipment is particularly important. Failures are associated with significant level aging and low replacement rates equipment, also possible simultaneous emergency decommissioning several elements as a result terrorist attacks.
 Based on analysis operating conditions high-voltage switching standards operational documentation method diagnosing technical condition SF6 circuit breakers proposed. This based use fuzzy set theory.
 To assess outages case failures, linguistic model proposed for determining total residual life probability failure various types. Which aggregation information individual functional units.
 An approach take into account importance units breaker terms impact by weight coefficients determined statistics. The ability estimate observation time interval.
 Tuning adaptation developed real provided adjusting parameters membership functions input variables using weighting inference weighted average truth.
 mathematical can be used component complex programs EPS. And formation preventive actions ensure reliability regime failures.
