Design of Building Energy- saving Device Based on Small Photovoltaic Inverter

为进一步降低建筑能耗,提出采用一种小型逆变装置为建筑进行补偿供电。为了提高小型光伏逆变装置的输出性能,降低输出电流畸变率,改善输出波形效果,采用一种基于瞬时电流直接控制的光伏逆变控制策略。通过仿真和实验,验证所用算法在光伏并网逆变装置上的可行性与实用性。

In order to further reduce building energy consumption, the article proposes that a small photovoltaic inverter can be used to compensate the power supply for buildings. It also points out that photovohaic inverter control strategy based on instantaneous current direct control method can be adopted to boost the output performance, to reduce the output current distortion and improve output waveform of small photo^roltaic inverters. The article also demonstrates the feasibility and practicability of the algorithm used in ggrid-connected PV inverters based on simulation and experiment results.
