摘要
实现变压器经济运行方式的前提是要有准确的设备参数和负载损耗曲线。作者通过变电站监控系统得到SCADA实时数据,采用以最小二乘逼近的外推法进行曲线拟合计算,得到变压器实际参数和功率损耗特性,并以此作为变压器经济运行的基础数据,实现了最优运行方式。
To possess accurate parameters of transformer and the power loss curve caused by loads is the presuppositions for economic operation of power transformer. A method based on SCADA to revise the parameter of transformer is proposed, in which firstly the real-time data is obtained from the substation SCADA system and is processed by extrapolated method approximated by least square method, then the fitting calculation of the curve is performed, finally the actual parameters of the transformer can be derived and it can be used as the basic data for economic operation of the transformer, thereby, the optimal operation of the transformer can be implemented.
