AUTOMATION OF LOW-VOLTAGE ELECTRICAL NETWORK MODE CALCULATION

Algorithms for calculating the steady-state mode of a three-phase low-voltage electrical network are considered. The algorithms are based on the well-known nodal potential matrix method using complex numbers. The Gaussian elimination method is proposed for solving the system of equations. To justify the application of this method, experimental studies were conducted, demonstrating that the load resistance of household consumers can be accurately approximated as linear and independent of voltage. The proposed algorithms were implemented in the LineCapacity software, designed for electrical network mode calculations and subsequent evaluation of network capacity. The accuracy of the calculations in LineCapacity was verified using two independent methods and is considered reliable. It was established that the practical significance of the LineCapacity software lies in its ability to assess the capacity of electrical networks at the design and operation stages
