光伏并网逆变器控制策略研究

随着光伏技术的日益发展,对太阳能的利用逐渐从无电地区发展到有电地区,许多国家都推出了光伏发电计划。在光伏并网发电系统中,逆变器实现把太阳能电池板产生直流电能转化为和电网同频同相的交流电能并且馈入电网,光伏并网逆变器是光伏并网发电系统的枢纽单元。

With the increasing development of photovoltaic technology, the use of solar energy to electricity area gradually from no development areas have electricity, many countries have introduced a photovoltaic power generation projects. In grid-connected PV system, the inverter to achieve the solar panels generate DC power into the grid with the same frequency and phase of the AC power and fed into the grid, photovoltaic grid inverters are grid-connected PV systems hub unit.
