Increase of reliability of operator-controlled power object functioning

Abstract

When controlling power objects operators face difficult situations of uncertainty and contradictions in instrument readings, release of displayed indications out of admissible value limit. The purpose of the paper consists in increasing reliability of automated power objects functioning applying the information system of operator activity support. The authors have developed the approach to operator activity information support in uncertainty. The matter of the approach consists in forming the models of changing phase coordinates and the control action by the object applied in the information support system. When indefiniteness occur during the object control the operator heuristic abilities are offered to be used to correct a certain part of a database, the model bases in cases when the operator manages to find quickly the way to solve the uncertainty accepted for practice. The approach developed reduces the operator mental load, increases his noise stability and capacity at occurrence of adverse psychological factors. The paper introduces the appropriateness of on-line correction of a database of information decision-support system.
