摘要/Abstract

摘要： 分布式发电并网将对传统电力系统造成影响，带来安全和电能质量等问题，通常通过控制电压源逆变
器(voltage source inverters, VSI)使分布式发电满足并网要求. 为此，研究了VSI型逆变器并网系统的关键技术，
主要对其滤波器进行探讨并给出设计方案，同时在电网跌落情况下研究了并网系统的锁相环技术以及低电压穿越
技术. 最后，利用MATLAB/Simulink搭建VSI型逆变器并网模型，并进行仿真验证.

关键词: 分布式发电并网, 电压源逆变器, 关键技术, 电网跌落

Abstract: Grid-connected distributed generation will affect security, power quality of the traditional power
system. Usually, voltage source inverters (VSI) are controlled to meet the requirements of grid-connected
distributed generation. Key technologies of the grid-connected VSI system are described in this paper. The
filter is analyzed and the design methods given. Meanwhile, the phase-locked loop (PLL) using the unbalanced
grid conditions and low voltage ride-through (LVRT) technology are studied. Based on the theoretical analysis,
a simulation model for the grid-connected Voltage source inverters (VSI) system is built and validated with
MATLAB/Simulink.

Key words: grid-connected distributed generation, voltage source inverters (VSI), key technologies, voltage dips
