摘要
新能源的有效利用方式是微电网,研究新能源接入后微电网的电能质量,能够快速分析并检测出问题所在,对电网的安全稳定运行具有重要意义,同时也能满足电力用户对电能质量越来越高的要求。为此,研究了新能源接入后微电网产生的电压偏差、频率偏差、电压波动、三相不平衡和谐波等传统电能质量问题,以及暂态投切和交互影响这两种特有的电能质量问题,系统地分析了风电及光伏电站接入后产生的影响。
As an effective use of new energy,studying the power quality of microgrid after new energy access can quickly analyze and detect the problems,which is of great significance to the safe and stable operation of power grid,and can also meet the increasingly high power quality requirements of power users.This paper carried out an in-depth analysis of the traditional power quality indexes such as voltage deviation,frequency deviation,voltage fluctuation,three-phase imbalance and harmonics,as well as two unique power quality problems of transient switching and interactive influence when wind power and photovoltaic power stations are connected to the microgrid.
