摘要
变压器是电力系统中最常见、也是最重要的能量变换设备,风电、光伏项目大量使用了电力变压器。掌握电力变压器的基本参数计算,能够利用仿真软件构建高质量的变压器模型并将其应用到具体的实验研究中,得出正确的结论是深入理解教材相关内容、提高电力系统分析理论素养的有效途径,利于新能源场站日常运维。本实验将在所给变压器参数的基础上,按照有关教材的结论进行电力变压器相关参数的计算,并基于SimPowerSystems中的三相双绕组变压器模型进行变压器参数设定,而后分别进行空载试验和短路试验,以检验该模型的准确性。
Transformer is the most common and important energy conversion equipment in power system.Power transformer is widely used in wind power and photovoltaic projects.Mastering the calculation of basic parameters of power transformer,being able to use simulation software to build high-quality transformer model and applying it to the specific experimental research,the correct conclusion is an effective way to deeply understand the relevant contents of teaching materials and improve the theoretical literacy of power system analysis,which is conducive to the daily operation and maintenance of new energy stations.Based on the transformer parameters given in this experiment,the relevant parameters of power transformer are calculated according to the conclusions of relevant textbooks,and the transformer parameters are set based on the three-phase double winding transformer(two winds)model in simpower systems,and then the no-load test and short-circuit test are carried out respectively to verify the accuracy of the model.
