CHARACTERS OF POWER COMPONENTS FORMING AND CALCULATION IN POWER SUPPLY AND CONTROL SYSTEM OF PLANTS WITH UNSTABLE LOADS

The work considers analysis of power supply energetic modes and control systems of electrical drive groups with transient loads by using the untraditional methods based on integral ratios and elements of nonlinear circuits spectral theory. As an example, it is shown that the reactive power of excavator EKG-4, 6 is two times larger of active power. The last is setting initial conditions for compensation systems choice.
