Abstract

To maintain the reliability of power supply, proper functioning of all equipment is necessary. The distribution transformers constitute a major part of a distribution system and its remaining life should be properly investigated. Renewable energy sources are integrated into a distribution system to reduce losses, improving voltage profile and save energy cost. This may affect the life of equipment present in the existing system. In this paper, a practical distribution system with installed rooftop solar photo-voltaic (PV) units is considered for investigation. Total study periods has been divided into three parts. The benefits of PV in terms of the life of the transformers have been quantified for the each part. For PV integration and time-series load flow simulation, MATLAB component objective model (COM) interface of OpenDSS is used. The actual load, load shape, temperature and irradiation data have been collected to prepare input to the simulation model. The results show that there is a considerable decrease in the rate of aging of the distribution transformer.

太阳能注入对配电变压器老化的影响

为了保持供电的可靠性，所有设备的正常运行是必要的。配电变压器是配电系统的重要组成部分，应对其剩余寿命进行合理的研究。将可再生能源集成到配电系统中，以减少损耗，改善电压分布并节省能源成本。这可能会影响现有系统中设备的使用寿命。本文以安装屋顶太阳能光伏发电机组的实际配电系统为研究对象。整个学习时间分为三个部分。光伏在变压器寿命方面的好处已被量化为每个部分。采用OpenDSS的MATLAB组件目标模型(COM)接口进行光伏积分和时间序列潮流仿真。收集了实际载荷、载荷形状、温度和辐照等数据，为仿真模型的输入做准备。结果表明，配电变压器的老化率有较大幅度的降低。
