Design of Multi-Terminal Output Current Signal Distributor for Grid-Connected Photovoltaic Power Generation

摘要: 光伏农业一体化并网发电项目，是能够实现对太阳能资源的有效利用，产出清洁绿色能源，还能实现高效种植的新能源电力电子项目。在农业并网发电系统的自动化领域多路控制中，电流信号分配器需要较强的可控性、安全性、高效性。以往的电流信号分配器对具体数值检测仍存在盲区，在安全预警方面也有所欠缺，电压电流转换多路独立性不够，导致存在互相干扰的情况。本设计聚焦农业光伏并网发电课题，基于输入信号的采集、输送、放大以及监测一体化原则，进行智能电流信号分配器的设计，从而取代传统依靠多元件完成的工作模式，满足自动化领域多功能控制。

Abstract: Photovoltaic agricultural technology not only makes effective use of solar resources and produces clean, green energy, but also enables efficient cultivation. In the automation field of grid-connected power generation systems in agriculture, current signal distributors need to be highly controllable, safe and efficient. Previous current signal distributors have blind spots for their specific value detection values, lacking in safety warning, and the voltage and current conversion multiplexes are not independent enough and can interfere with each other. This design focuses on the topic of grid-connected agricultural photovoltaic power generation, based on the acquisition, transmission, amplification and monitoring of the input signal as a whole, the design of intelligent current signal distributor, thus replacing the traditional work mode that relies on multiple components to complete, to meet the automation field multi-functional control.
