三维正弦稳态场矢量最大值的直接计算方法
Direct Calculation Method for Maximum of 3-D Sinusoidal Steady-State Field Vector
摘要
Abstract
Sinusoidal steady-state field exists widely in power transmission and transformation system and other practical engineering.It is very important to carry research to its variation law and maximum.So further study on three dimensional sinusoidal steady-state field is required to compute the maximum and understand the endpoint trajectory of three dimensional field vector.In this paper,analytical formulas for the maximum,the minimum and direction cosine of 3-D sinusoidal steady-state field are deduced based on phasor.It is demonstrated that the endpoint trajectory is an elliptical orbit in three dimensional space by coordinate transformation.The availability of the formulas is verified by comparing the computational results with the measured results.关键词
