并、串联补偿在分布式发电系统中的运用

Application of Parallel and Series Compensation in Distributed Power Generation System

随着分布式发电在电力系统中的占比不断增大,分布式发电在生产生活中的作用也愈发重要。由于分布式发电发展快、并网标准不一,为此存在电压不稳定、谐波量较大、穿越能力不强等不利因素,这些因素会影响电力系统供电质量及分布式发电的使用效率。串联补偿对电压稳定性有明显效果,并联补偿则对系统的电流、谐波及负载适应性有积极作用。文章对并、串联补偿在分布式发电系统中的应用及仿真进行了详细的介绍。

With the increasing proportion of distributed power generation in power system,the role of distributed power generation in production and life is becoming more and more important.Due to the rapid development of distributed power generation and different grid connection standards,there are adverse factors such as unstable voltage,large amount of harmonic wave and weak ride through capacity,which will affect the power supply quality of power system and the use efficiency of distributed power generation.Series compensation has obvious effect on voltage stability,while parallel compensation plays a positive role in current,harmonic wave and load adaptability of the system.This paper introduces the application and simulation of parallel and series compensation in distributed power generation system in detail.
