Abstract

This paper presents Silicon Controlled Rectifier (SCR) based power flow control for grid integration in home-scale photovoltaic system. Power flow control is used to control the power flow from the grid if the power from solar panel and battery cannot meet the power requirements of the load. To control the power on the grid, a full-wave SCR circuit is designed. The full-wave SCR circuit serves to convert 220 Volt AC from the grid into 36 Volt DC. The effect of the delay angle of the SCR on the full-wave SCR output voltage is shown in this paper. A filter with a combination of an inductor (L) and a capacitor (C) which is assembled into an LCLC filter in parallel with the load aims to smooth out ripples in the output voltage. The circuit is designed and modeled in The PSpice program code, then simulated and analyzed. The simulation and implementation test results show that the voltage can work at the setpoint voltage at 100-ohm and 50-ohm loads. The full-wave SCR circuit can supply up to 1.8kW based on the simulation results.

基于scr的家庭光伏并网潮流控制

提出了一种基于可控硅的家庭光伏并网潮流控制方法。潮流控制是指当太阳能电池板和蓄电池的功率不能满足负荷的功率要求时，对电网的潮流进行控制。为了控制电网上的功率，设计了全波可控硅电路。全波可控硅电路用于将220伏交流电从电网转换成36伏直流电。本文给出了可控硅延时角对全波可控硅输出电压的影响。由电感(L)和电容(C)组成的滤波器与负载并联组装成LCLC滤波器，目的是消除输出电压中的波纹。在PSpice程序代码中对电路进行了设计和建模，并进行了仿真和分析。仿真和实现测试结果表明，该电压在100欧姆和50欧姆负载下均能在设定值电压下工作。仿真结果表明，全波可控硅电路的供电功率可达1.8kW。
