Research of starting characteristics for high-voltage motors based on numerical method

Abstract

In order to more accurately calculate the starting characteristics of the high-voltage motor and determine the impact on the grid, this paper establishes the dynamic model. The starting characteristic of the high-voltage motor is calculated based on the numerical method. In addition, this paper analyses the influence of the load changes on the starting characteristic. Compared with the steady-state characteristic curve, the result is much closer to the practical situation. This method provides more accurate references for the high-voltage motor design and the determination of starting mode.
