LED-based street and road lighting installations generate reactive power, particularly when they are dynamically dimmed. It contributes to power loss and efficiency reduction of the grid. Reactive power can be compensated by installing additional dynamically connected inductors in lighting control cabinets. However such an approach significantly increases the cost of the lighting infrastructure. The goal of this paper is to propose another, low cost approach to reactive power compensation for dynamically dimmed lighting installations. It is based on connecting fixed settings inductors at lighting control cabinets. The inductors settings are calculated by the proposed algorithm for city-scale lighting systems. A synthetic benchmark example with 798 circuits and 14,019 luminaires confirms its applicability. The algorithm objective is to completely eliminate capacitive reactive power and to keep inductive reactive power within acceptable limits. It is an extended version of the ICCS 2020 paper [9].

无功补偿算法在大型路灯照明中的应用

基于LED的街道和道路照明装置会产生无功功率,尤其是当它们动态变暗时。它有助于电网的功率损耗和效率降低。通过在照明控制柜中安装其他动态连接的电感器,可以补偿无功功率。然而,这种方法显着增加了照明基础设施的成本。本文的目的是为动态变暗的照明设备提出另一种低成本的无功功率补偿方法。它基于在照明控制柜上连接固定设置的电感器。电感器设置是通过针对城市规模照明系统的拟议算法来计算的。具有798条电路和14019个照明器的综合基准示例证实了其适用性。该算法的目的是完全消除容性无功功率,并将感性无功功率保持在可接受的范围内。它是ICCS 2020文件[9]的扩展版本。
