ABSTRACT
The peculiarities of the operation of distributed generation systems lead to a change in the requirements for the reliability and safety of the power distribution systems in which they are integrated. To meet the increased requirements, continuous monitoring of the insulation parameters is often used. In the case of a sudden touch, such a system is not effective since the response time of the protection device, which consists of the signal processing time and the operating of the actuator, is crucially important. To develop an effective resolver system based on Matlab environment was determined the most successful design of an analog prototype for an operational signal with a frequency of 200 Hz. As a result, the processing time was established, which varies widely from 3.5 to 19 ms. Considering the known indicators, namely the frequency and number of operational signals, a signal processing system was developed using the vector-matrix analysis method. As a result of modeling the processing characteristics of operational signals (at a sampling rate of 1 kHz), the system quick-response was 3 ms, with the possibility of its further decrease as its productiveness increases.
