摘要

直流微电网(MG)在配电层面的应用,特别是在家庭和商业应用中,正在获得动力。直流电由于没有无功功率,损耗低,因此更有利可图。因此,试图实现临界和非临界负载连接到直流电弹簧的影响,而直流电弹簧是直流永磁系统的组成部分。由于降压斩波功能满足能量要求,因此将斩波电路命名为电弹簧。MG系统的输入来源于太阳能光伏模拟器的实时输出。为了避免多次AC/DC转换,太阳能直流电除了给电池充电外,还直接馈送给负载。实验结果表明,在输入电源不确定的情况下,所制备的直流弹簧在保持临界负载的恒定电压方面起着至关重要的作用,从而提高了电池的容量。

PERFORMANCE EVALUATION OF DC ELECTRIC SPRING PLACED IN MICRO GRID SYSTEMS USING SOLAR PV EMULATOR
The use of D.C micro grids(MG) in the electricity distribution level especially for domestic and commercial applications is gaining momentum. D.C power is more lucrative because of low losses due to the absence of reactive power. Hence an attempt is made to realize the effect of both critical and non- critical loads connected to DC Electric spring which forms an integral part of DC MG system. As the buck chopper function meets the requirement of energy, the chopper circuitry is christened as Electric spring. The input to the MG system is obtained from a real time output of solar PV Emulator. In order to avoid multiple AC/DC conversions, solar DC power is directly fed to the loads in addition to charging the batteries. During uncertain conditions of the input supply, the so fabricated DC Electric Spring plays vital role in maintaining constant voltage at critical loads which (this result) leads to the enhancement of the capacity of the battery which is evident from the experimental results.
