太阳能并网发电系统的MPPT及孤岛检测技术
MPPT and anti-islanding of photovoltaic grid-connected system
摘要
Abstract
The mathematical model of photovoltaic cell is built based on the equivalent circuit of photovoltaic cell, and the characteristic curves of photovoltaic cell are analyzed. Through comparing the advantages and weaknesses of the existing MPPT (maximum power point track) methods, an improved perturbation and observation (P&O) algorithm with constant-voltage-start and variable step size is proposed. In view of the exiting islanding detection method, the active frequency drift islanding detection is adopted. A mathematical model of the photovoltaic cell, as well as the simulation model of MPPT and active frequency drift islanding detection method is built on the platform of Matlab/Simulink, and experimental study on them are also carried out, and the simulation and experimental results show its feasibility and rationality.关键词
