The fuzzy-statistical risk estimation method of motor load stability failure in power subsystem is proposed as integral indicator of its reliability. This method allows to consideration equipment faults, possibility of system failure and failure's aftereffects. Algorithm of power subsystem fuzzy-statistical modeling for the risk estimation of motor load stability failure is proposed. Fuzzy-statistical modeling of real power subsystem – supply scheme of chemical plant is carried out. By its results, risk of subsystem reliability decreasing in the case of important motor stability failure is obtained.

N. BUSLOVA, R. NAGORNYI
In connection with increasing on-line diagnostic role without switching-off methods which are used for localization partial dischargeі in power oil transformers are represented. Analyses were carried out in use condition of each methods and ones advantages and disadvantages were established. In terms of precision and simplicity of implementation, pseudo-time approach which bases on principals Global Positioning System (GPS) was accepted.
