The article deals with the method of analysis power grid objects using Bollinger indicators. This is necessary for processing electrical characteristics in power supply systems and allows you to determine full range of electrical values and their current deviation from average value. This oscillating indicator makes it possible to respond quickly to changes in electrical characteristics and achieve the maximum efficiency of transmitted power. The methods of wavelet transformation of high-frequency signals, which are proposed to be used, identify and localize negative factors (frequency and amplitude oscillations, voltage dips, etc.) affecting quality of electricity and are also considered. It is found that the amplitude and frequency of negative perturbations may differ several times, and in order to automatically track such phenomena, it is advisable to use Bollinger indicators As a result, the latter conditionally limit wavelet function from above and below, thus crossing amplitude or frequency of spikes in wavelet of any indicators on the control system, the signal from the control room is sent on the elimination of negative impacts.
