Guide for the application of transformer connections in three - phase distribution systems 三相配電系統(tǒng)變壓器連接應(yīng)用指南
The core mass of single - phase and three - phase distribution transformers with wound core is analyzed and calculated . the examples are given 摘要對單相、三相卷鐵心配電變壓器的鐵心質(zhì)量進行了分析和計算,并給出了實例。
Secondly , measuring arrangement in three - phase distribution systems , decomposing jacobian matrix algorithms and how to choose pseudo - measurement weight are discussed 其次,對三相系統(tǒng)的量測設(shè)置,分解雅可比三相狀態(tài)估計算法和偽量測權(quán)值的選取進行了闡述。
