A Decision Support System for Control over Load Modes in the Cable Unit

Abstract

An increase in the capacity of cable lines is possible due to the use of mathematical models of heat and mass transfer processes instead of determining the long-term permissible currents using regulatory documents that do not take into account the full load mode of the cable structure. The introduction of digital technologies into the processes of control and management of power-supply systems will ensure an increase in the reliability and quality in these systems. The paper suggests the introduction of a decision support system (DSS) into the system for control over the load modes of cable units, which makes it possible to determine the optimal load modes for specific operation conditions based on the temperature restrictions. The DSS, which is based on mathematical models, helps to develop control actions to force a reduction in the load of some lines when permissible temperatures are possibly exceeded. The recommendations for reducing the load should take into account the range of possible working currents for each line, which depends on the customer category and technological capabilities. The optimal operation mode, for which the insulation temperatures are not higher than permissible values and a relative decrease in the power consumption is minimum, has been selected.
