Abstract

This paper presents the design, implementation, and performance evaluation of a novel 50 kvar Static Var Compensator (SVC) integrated with an Internet of Things (IoT) controller for a low-voltage power distribution system in Moscow. This integration enhances real-time monitoring and control capabilities over traditional SVC systems. The study focuses on advanced control systems for reactive power compensation, voltage stabilization, and overall system efficiency. Data collected over two months demonstrate the SVC’s effectiveness in maintaining a stable power factor close to unity and reducing reactive power demand. The device successfully kept voltage levels within acceptable limits across all phases, reducing fluctuations and ensuring balanced voltage levels. Key findings include enhanced reactive power compensation, voltage stabilization (minimum voltage not less than 218 V), improved system efficiency (reactive power demand from the source near zero most of the time), and significant improvements in power quality and grid stability. The case study at Kosinskaya Street, Moscow, confirms the device’s role in improving power quality and grid stability. These results support the broader deployment of IoT-integrated SVC technology in low-voltage power distribution systems.

利用物联网流数据对配电系统低压 SVC 进行性能评估

本文介绍了一种新型 50 kvar 静变量补偿器（SVC）的设计、实施和性能评估，该补偿器与物联网（IoT）控制器集成，用于莫斯科的低压配电系统。与传统的 SVC 系统相比，这种集成增强了实时监测和控制能力。研究重点是无功补偿、电压稳定和整体系统效率的先进控制系统。两个月来收集的数据证明了 SVC 在维持接近统一的稳定功率因数和减少无功功率需求方面的有效性。该装置成功地将各相电压水平保持在可接受的范围内，减少了波动，确保了电压水平的平衡。主要发现包括无功功率补偿增强、电压稳定（最低电压不低于 218 V）、系统效率提高（大部分时间电源的无功功率需求接近于零）以及电能质量和电网稳定性显著改善。莫斯科 Kosinskaya 街的案例研究证实了该设备在改善电能质量和电网稳定性方面的作用。这些结果支持在低压配电系统中更广泛地部署物联网集成 SVC 技术。
