Abstract
The article proposes an imitation model of an electrotechnical street lighting system, which includes the following components: a power supply model, a lighting network model, a lighting model of the lighting installation, a model of the street lighting control system and a model of changing environmental parameters. The Simulink program of MatLab mathematical package was chosen as simulation environment. The model of the lighting network based on the iterative method of calculation is realized, which allows calculating the steady-state conditions of the electrical part of the street lighting system. The model is implemented in the form of an m-function in the MatLab language and in the form of a functional block of the Simulink environment. Likewise, the lighting model of a street lighting installation was implemented taking into account the external illumination and the dependence of the light flux of various types of lamps on the value of the supply voltage. In addition, a model of various algorithms for controlling the street lighting system is implemented. The resulting simulation model allows analyzing the operation of electrotechnical street lighting systems over long periods through computer simulation thereby enabling the evaluation of the correctness of design solutions and the effectiveness of various energy efficiency measures.
