大型工商业分布式光伏电站的电气设备选型与优化策略

摘要

随着分布式光伏在大型工商业场景中的快速部署，电气系统选型策略成为工程设计中的关键环节。本文以厦门时代新能源科技有限公司屋顶光伏项目为依托，围绕电气设备配置选型、防逆流控制与电能质量评估展开分析，构建了涵盖一次设备、二次保护与运行评估的全流程选型体系。研究结果表明该项目各类电气设备配置合理、控制逻辑闭环完整、运行参数稳定，具备代表性与可复制价值。

Abstract

With the rapid deployment of distributed photovoltaic power in large-scale industrial and commercial scenarios, the selection strategy of electrical systems has become a key link in engineering design. Based on the rooftop photovoltaic project of Xiamen Times New Energy Technology Co., LTD., this paper analyzes the configuration and selection of electrical equipment, anti-backflow control and power quality assessment, and constructs a full-process selection system covering primary equipment, secondary protection and operation assessment. The research results show that the configuration of various electrical equipment in this project is reasonable, the control logic closed loop is complete, the operating parameters are stable, and it has representativeness and replicable value.
