摘要
在新能源发电并网的过程中,由于多数能源的波动性较强,输出功率稳定性差,以及新能源并网中所需电力电子装置产生的附加谐波,都会引起新能源并网的电能质量问题。综述了新能源并网引起的电能质量问题,简述了这些问题带来的危害,并分析了新能源并网引起的电能质量问题的原因。
Because most of the new energy fluctuation is strong,and the output power lacks stability,and the power electronic device in the grid of new energy power brings harmonic,all these will lead to some quality problems. This paper summarized the power quality problems caused by the new energy grid-connected,briefly described the harm caused by these problems,and analyzed the reasons for the power quality caused by the new energy grid-connected.
