The article proposes a modern method of fault location for 6 kV networks according to empirical criteria for different types of emergency modes. When developing the criteria, the modules of phase voltages and currents at the beginning of the line, at the end of the line, and both at the beginning and at the end of the 6 kV line were used. It has shown that the error of the fault location method with one-sided measurement is below 6.71 %, except for the fault modes “ground fault with subsequent breakage” and “two-phase short-circuit”. However, while using double-sided metering at the beginning and end of the line, all of the emergency modes considered are identified, with a method error of below 4%.
A modern hierarchical structure of the automated process control system of an electric grid company is proposed, according to which at each control level an intelligent module is provided, allowing to integrate the local system into a common trusted software environment for the purpose of operational management in current and emergency situations. The model of information flows of the digital integration platform as a common trusted software environment for the automated control systems of the electric grid company was developed. In the MathCad environment the method of fault location using empirical criteria is implemented, designed to support the decision of the grid control centre dispatcher in current and emergency situations.
