It has been shown that the analysis of power conversion processes in all the power structure elements, based on instantaneous power components, underlies the estimation power channel of electromechanical systems carrying capacity. Presence of power variable component reflecting energy exchange processes in the system results in the decrease of the carrying capacity of the object power channel. It has been established that effective power is a quality measure for power processes in the system. An index of system power controllability has been offered. An index of power channel carrying capacity has been offered.

A power approach to estimation of electromechanical complexes controllability using instantaneous power method has been offered. It has been determined that power controllability characterizes the quality of energy conversion processes in the system, reflects manifestation of nonlinear properties of the object. A mathematical procedure for determination of power losses for the whole power channel of electromechanical complex power conversion has been developed. It has been shown that formation of balance equations of separate instantaneous power components underlies the estimation of electromechanical complexes power controllability.
