冲击负荷接入对配电网电压质量影响及其无功配置研究

Research on Impact of Shock Loads Integration into Distribution Network on Voltage Quality and Reactive Power Configuration

提出了描述冲击负荷冲击特性的3个维度特征,包括无功、时间、变化率维度,在此基础上建立仿真模型,详细分析了冲击负荷接入对配电网电压质量的影响,着重对比不同维度特征引起冲击负荷对配电网电压质量影响的差异性,并针对冲击负荷接入的无功配置提出配置基本原则及建议,对含冲击负荷用户接入的无功配置起指导性作用。

Three dimensions of characteristics to describe the shock load, including reactive power, time, rate of change was proposed in this paper, then the simulation model for deep analysis on the impact of the shock loads inte- gration into distribution network on voltage quality was established. The differences of the impact on the voltage quali- ty due to different dimension characteristic were illustrated by comparison. Finally the basic principle and advices for shock load access was proposed, and could give guidance in reactive power configuration for shock loads integrated into distribution network.
