电力系统稳定性方法探究

电力系统稳定性问题是电业生产当中所要遇到的首要问题,是指给定运行条件下的电力系统,在受到扰动后,重新回复到运行平衡状态的能力。系统中的多数变量可维持在一定的范围,使整个系统能稳定运行的问题。如果能够,则认为该系统在正常运行方式下是稳定的,反之,若系统不能回到原来的运行状态或者不能建立一个新的稳定运行状态,则说明系统的状态变量没有一个稳态值,而是随着时间不断增大或振荡,系统是不稳定的。本文主要探究了电力系统的稳定性问题,从电力系统的静态稳定分析跟暂态稳定分析加以研究,其中暂态稳定分析包含了数值解法跟直接解法两种方法。

Power system stability problem is to the primary problems of electric power production, is to show when the system is in a normal way after a disturbance can run back to the original state after a certain amount of time, or the transition to a new stable running status. If you can, argues that the system is stable under normal operation, on the contrary, if the system cannot return to its original status or not to establish a new stable operation condition, the system state ,~ariables without a steady value, but with increasing time or oscillation, the system is unstable. This paper mainly explores the problems of the stability of power system,and from the static stability analysis and transient stability of power system analysis and study, the transient stability analysis of numerical solution with direct solution contains two methods.
