基于多数据来源的变压器档位估计方法

State Estimation of Transformer Tap Position Based on Multi-source Data

提出了一种变电站内变压器分接头位置估计方法,该方法采用了分层估计、全局优化的计算模式,并利用实际算例进行分析验证。数值结果表明,由于充分利用了变电站内数据的多样性和冗余性,该计算模式具有较高的实用性和准确性,可实际应用于变电站状态估计,提高变电站为电网运行和维护服务的支撑能力。

This paper presents a substation transformer tap position estimation method, which employs multi-level op- timal computing mode, and is analyzed and tested by practical calculation example. The numerical results indicate that this method has high practicality and accuracy due to the full use of the diversity and redundancy of substation da- ta, and can be applied in substation state estimation in order to improve substation＇s support capabilities for grid oper- ation.
