单相连接设备的数量（电动汽车充电器、光伏逆变器等）具有高电功率和长时间操作的电压不平衡持续增加，并且可能导致电压不平衡的显著增加。为了对公共低压电网中的电压不平衡进行真实的仿真，必须考虑居民负荷对不平衡的贡献。本文提出了一种用于不平衡研究的家庭负荷概率模型。该模型是基于一组不同规模的家庭在不同的网络的功率测量。在此基础上，建立了一个适用于家庭负荷的不平衡潮流模型，并进行了验证。仿真和测量结果进行了讨论，并提供了简化的方程来估计一组家庭的不平衡和最大功率。
The number of single phase connected devices (electric vehicle charger, photovoltaic inverters, etc.) with high electrical power and long periods of operation increases continuously and may lead to a significant increase in voltage unbalance. In order to perform a realistic simulation of voltage unbalance in public low voltage networks, the contribution of residential loads to unbalance has to be included. This paper presents a probabilistic model of household loads for unbalance studies. The model is based on a set of power measurements of households of different size in different networks. Based on these data an unbalanced load flow model for household loads is developed and validated. Both, simulation and measurement results are discussed and simplified equations to estimate unbalance and maximum power of a group of households are provided.
