The static and dynamic reserve of voltage in input of voltage autonomous inverter being a component of parallel power active compensator on the physical realizability of inactive current components with the determined response, pulsations amplitude and commutation frequency of invertor switches was considered. Invariance of closed system of automated power quality regulation with relay control to the parametric and external disturbances is provided by the dynamic voltage reserve calculated from the obtained expressions. Special attention is given to the possibility of using this system in mining. Proposed approaches also can be used in the training of engineers in the electrical and mining industries.
