还可以测量接地电压与中性线或中性线之间的电流，使其可能是三相不平衡负载，可调整不平衡负载的位置，然后确定负载的确定点。三是定期、不定期地进行负荷测量，特别是在用户负荷的大范围运行和高峰负荷时，加大实际测量，测量时间接近用户电流低压和配电变压器的低线输出，而且便于准确了解设备的运行情况，做大量有用的工作量平衡和合理分配。由于大多数家庭的负荷是单相负荷和三相负荷，负荷的大小和耗电量在不同的时间是不同的。可以看出三相不平衡电流网格相对存在。这种不平衡的功耗是不规则的，无法提前预测。三相电压供电系统的载波长期不均匀。对于三相不平衡电流，除了电力部门作为合理可行的负荷分配外，几乎没有有效的解决方案。相位不平衡是电能质量问题之一。在分析研究的基础上，在三相不平衡配电网中，找出三相不平衡产生的原因，从而导致三相设备和设备的不平衡，对电力设备和电网的安全经济运行、有序运行具有深远的意义。本文以三相不平衡35kV配电网工程为背景，通过建模、仿真和研究，找出三相电压不平衡的原因，还提出解决方案和方法。本文的研究手段和成果不仅解决了实际问题，而且为提高网格管理水平提供了有效的理论分析方法。关键是：三相电压不平衡是一样的。

It can also measure the current between the grounding voltage and the neutral line or the neutral line, so that it may be a three-phase unbalanced load, adjust the position of the unbalanced load, and then determine the determination point of the load. Third, carry out load measurement regularly and irregularly, especially when the user's load is running in a large range and at peak load, increase the actual measurement, the measurement time is close to the user's current low voltage and the low-line output of distribution transformer, and it is convenient to accurately understand the operation of equipment, and do a lot of useful workload balance and reasonable distribution. Because most of the household load is single-phase load and three-phase load, the load size and power consumption are different at different times. It can be seen that the three-phase unbalanced current grid exists relatively. This unbalanced power consumption is irregular and cannot be predicted in advance. The carrier of three-phase voltage power supply system is not uniform for a long time. For the three-phase unbalanced current, except for the power sector as a reasonable and feasible load distribution, there is almost no effective solution. Phase imbalance is one of the power quality problems. On the basis of analysis and research, in the three-phase unbalanced distribution network, find out the causes of the three-phase imbalance, resulting in the imbalance of three-phase equipment and equipment, which has far-reaching significance for the safe and economic operation and orderly operation of power equipment and grid. In this paper, based on the background of three-phase unbalanced 35kV distribution network project, through modeling, simulation and research, the causes of three-phase voltage imbalance are found out, and solutions and methods are proposed. The research methods and results of this paper not only solve the practical problems, but also provide an effective theoretical analysis method for improving the level of grid management. The key is: the three-phase voltage imbalance is the same.<br>
