查询词典 Humboldt Current

The main contents of this thesis are:(1) The new phase segregated current differential protection based on distributed parameter is proposed. The new protection can calculate the current at the fault point in real time, so its performance is hardly affected by distributed capacitance of transmission line.

What this paper finished mainly work as follows: Five-phase hybrid step motor driver system with fixed-chopping frequency and constant total current driving is fully described. Mathematical model of the system, included the current control circuit, power driving circuit and five-phase hybrid stepping motor is established. The steady modeling of the system is established and studied. Based on the steady modeling of the system, dynamic modeling of the system is studied and single step response characteristic is constructed with MATLAB/Simulink. The simulation results, which is certified by the theory analysis, coincide with the theory analysis.
