城市道路照明变压器配置优化方法研究

Research on Optimization Method of Transformer Configuration for Urban Road Lighting

照明变压器的配置是道路照明的基础,在实际中常采用工程经验确定变压器的数量及位置,易造成变压器数量过多,带来利用效率低、投资大、美观性下降等问题。基于此,提出一种城市道路照明变压器配置优化方法。该方法首先在考虑线路压降、供电半径等条件下,建立了以变压器布置数量最少与线路平均压降最小为目标函数的优化模型;然后利用粒子群算法对该模型进行优化求解;最后,基于工程算例模型对所提方法进行仿真验证,证明该方法的有效性。该方法适用于城市道路照明工程设计规划,可为照明变压器的配置提供参考依据。

The configuration of lighting transformers is the basis of road lighting. In practice, engineering experience is often used to determine the number and location of transformers, which is easy to cause too many transformers, resulting in low utilization efficiency, large investment and reduced aesthetics. Based on this, an optimization method of transformer configuration for urban road lighting is proposed. Firstly, considering the line voltage drop and power supply radius, the optimization model with the minimum number of transformers and the minimum average line voltage drop as the objective function is established;Then the particle swarm optimization algorithm is used to optimize the model;Finally, the effectiveness of the proposed method is verified by simulation based on an engineering example model. This method is applicable to the design and planning of urban road lighting engineering, and can provide a reference basis for the configuration of lighting transformer.
