摘  要:
光伏并网发电是太阳能光伏发电应用发展的趋势。并网逆变器是光伏并网发电系统核心部件之一,基于TM S320LF2407 DSP芯片控制的并网系统。利用DSP丰富的外围电路和强大的功能实现并网系统的所有工作、控制和相应的保护功能等。并网逆变器采用前级DC/DC的boost升压结构电路,减少了系统体积和重量;后级DC/AC逆变器采用全桥逆变电路;且具有最大功率跟踪和反孤岛效应等功能。以DSP为控制核心的光伏并网系统具有可靠性强,工作效率高,稳定性好等优点。其加快了光伏并网发电系统的应用推广。

摘  要:
PV grid-connected power generation is the trend of the application and development of solar PV power generation.PV gridconnected inverter is one of the components of PV grid-connected power generation system.Operation,control and protection of PV gridconnected system based on TMS320 LF2407 DSP chip are realized according to DSP with richer external circuit and stronger function.Grid-connected inverter adopts the front DC/DC boost structure converter circuit,able to reduce system volume and weight;the later DC/AC inverter is(H-bridge) circuit.There is maximum power point tracking and anti-islanding function etc.Grid-connected system based on TMS320 LF2407 DSP has strong credibility,high efficiency and good stability.Finally the results prove that grid-connected inverter will improve application and expansion of PV grid-connected power generation(system).
