交流电动机的矢量控制(Transvector Contrl)理论,从理论上解决了交流电动机转矩的高性能控制问题。其基本思想是在普通的三相交流电动机上设法模拟直流电动机转矩控制的规律,在磁场定向坐标上,将电流矢量分解成产生磁通的励磁电流分量 和产生转矩的转矩电流分量 ,并使两分量互相垂直,彼此独立,然后分别进行调节。这样,交流电动机的转矩控制,从原理和特性上就与直流电动机相似了。因此,矢量控制的关键仍是对电流矢量的幅值和空间位置的控制。(AC motor vector control (Transvector Contrl) theory, control theory to solve the problem of high-performance AC motor torque. The basic idea is to try to simulate the DC motor torque control law in the ordinary three-phase AC electric motor in field-oriented coordinates, the current vector decomposed to produce the excitation current component of the magnetic flux generating a torque current component and torque, and two components perpendicular to each other, independently of each other, and then were adjusted. Thus, AC motor torque control, the principle and characteristics of the DC motor on and similar. Therefore, the key vector control is still the amplitude and spatial position of the current vector control.)

design primary power-system of 110kV substation and draw main
electrical one-line diagram and others. There are two main
transformer in the substation in which main electrical connection
can be divided into three voltage grades: 110kV, 35kV with 10kV.It
deposits sectionalized single bus bar scheme, sectionalized single
and transfer bus bar and sectionalized single bus bar scheme per
grade.)
