基于分布式电力系统电压振荡的研究

Research on Voltage Oscillation in Distributed Power System

随着社会经济的不断发展,电力市场逐步建立起来,而分布式电力系统(DGs)在电力市场中的重要程度是不容忽视的。分布式电力系统的引进不仅可以减少投资成本,而且其发电方式简便,因此分布式电力系统逐渐受到社会各界的广泛关注。分布式电力系统的电源如果在其接入位置和接入容量发生改变时,会对分布式电力系统产生有变化规律的电压震荡,从而对整个电力系统的性能产生影响。本文主要先介绍分布式电力系统的相关概念,然后再介绍分布式发电系统的作用特点,最后根据相关理论来分析分布式电力系统电源接入对系统电压震荡的影响。

With the continuous development of social economy,the power market is gradually established,and the importance of distributed power system(DGs)in the power market can not be ignored.The introduction of distributed power system can not only reduce investment costs,but also simplify the way of generating electricity,so the distributed power system is gradually accepted.It has attracted wide attention from all walks of life.If the power supply of the distributed power system changes its access location and capacity,it will produce regular voltage oscillation in the distributed power system,which will affect the performance of the whole power system.This paper first introduces the related concepts of distributed power system,then introduces the function characteristics of distributed generation system.Finally,according to the relevant theory,it analyses the impact of distributed power system access on system voltage oscillation.
