Automation of Control of Modes of Power Supply and Lighting Systems of Cities

Abstract

In the work under consideration, the power supply and lighting systems of cities are considered as complex geographically distributed man-machine systems, which, in turn, are part of higher-level systems - electric power systems or their subsystems. They have common elements with them (supply and distribution networks of high and medium voltage), as well as common power supplies and means of regulation and control. This makes them mutually influencing and interrelated and requires the use of methods and technical means of control, adapted to the parameters and modes of urban energy networks and, basically, focused on structural and parametric integration and control systems for objects of energy systems. The structure of an automatic control system, criteria and parameters for controlling the modes of power supply and lighting systems in cities, differing in the distribution of parameters in space, processes in time, as well as a low level of correlation of voltage and reactive power graphs, are proposed, and are based on the application of the Smart-Light concept. It is based on a distributed multi-level control system with dispersed active elements based on the use of phase-shifting booster transformers. This ensures the possibility of unrelated control of voltage modes, active and reactive power. The foregoing opens up the possibility of controlling the voltage modes at any point in the network without affecting the modes of other consumers. The conceptual system for controlling the modes of electrical networks of power supply and lighting systems in cities allows us to take into account their features associated with the color-light effect of lighting on the flora and fauna, as well as adjacent systems of a higher level — electrical power systems and networks. The above allows us to consider the power supply and lighting systems of cities as complex biotechnical systems and manage them taking into account, in addition to the economic criterion, also the criteria of social and environmental efficiency.
