OPTIMIZER OF A DIAGNOSTIC SUBSYSTEM OF POWER INSTALLATIONS (SKAIS) STATE FOR SOLUTION OF PROBLEMS OF MAINTENANCE SERVICE

Abstract

The paper considers the features of the diagnostic control of power installations of power plant via expert diagnostic system of functional hybrid type named SKAIS. SKAIS, the system of control, analysis and monitoring of changes in the power plant state, is a dialogue modedriven software system, designed for diagnostics and expertise of any power plants. SKAIS makes it possible to diagnose decline in economical efficiency, define amount, reasons and danger of current changes, forecast state, evaluate reliability, remaining life, longevity, risk level and damage from further power installation exploitation at early stages (with the use of accelerated tests). SKAIS system makes decisions toward surmounting the conflict (maintenance or restriction) with the presentation of recommendations, prepared in the knowledge base (in the form of end products – decision rules) to operative and maintenance personnel of a thermal plant. The data base and knowledge base about all forced stops and equipment defects, deviations from the exploitation norms are made for that end.
