Abstract

The necessity of modeling the operating modes of outdoor lighting lines with a voltage of 0.23/0.4 kV is substantiated. The choice of the optimal configuration of the lighting line while ensuring the standardized values of illumination and brightness on the working surface is recommended to be carried out by comparing several variants with different positions of pillars, types of light intensity curves, the number and power of luminaires. The results of the lighting calculation are the basis for modeling the electrical operation modes of outdoor lighting lines, which allows determining the operating parameters (node voltage, active and reactive power, current, voltage drop, loss of active and reactive power in individual sections). The obtained data can be used to select the cross-sectional area of conductor cores and forecast the power consumption of outdoor lighting, taking into account the specific features of light flux regulation (dimming). As a rule, outdoor lighting lines are connected to one power point. The use of outdoor lighting lines with bilateral supply for main streets and circular roads of relatively long length is proposed which will not only make it possible to increase the reliability of power supply of lighting installations, but also to use conductors with a smaller cross-section area of the cores. The electrical load of light sources is assumed on the basis of static characteristics. Modeling of the electrical modes of the outdoor lighting network is carried out taking into account the higher harmonics of current and voltage. The rational operation mode of the outdoor lighting line is determined by the magnitude of the voltage deviation from the nominal value, the indicators of non-sinusoidality and voltage asymmetry at the power supply point. Additional possibilities for modeling the modes of operation of lighting lines are to search for damage (detection of short circuits, determination of the presence of faulty lamps).

室外照明线路运行模式建模的特点

论证了0.23/0.4 kV室外照明线路运行模式建模的必要性。在保证工作面上照度和亮度的标准值的前提下，建议通过比较不同柱子位置、光强曲线类型、灯具数量和功率的几种变型来选择照明线路的最佳配置。照明计算的结果是室外照明线路电气运行模式建模的基础，从而可以确定运行参数(节点电压、有功和无功功率、电流、电压降、各路段有功和无功损耗)。所获得的数据可用于选择导体芯线的截面积和预测室外照明的功耗，同时考虑到光通量调节(调光)的具体特点。通常，室外照明线路连接到一个电源点。对于较长的主要街道和环形道路，建议采用双边供电的室外照明线路，这不仅可以提高照明设施供电的可靠性，而且可以使用芯截面面积较小的导体。光源的电负荷是在静态特性的基础上假定的。考虑电流和电压的高次谐波，对室外照明网络的电气模式进行了建模。室外照明线路的合理运行方式是由供电点电压偏离标称值的大小、非正弦性和电压不对称的指标来决定的。对照明线路的操作模式进行建模的其他可能性是搜索损坏(检测短路，确定故障灯的存在)。
