摘　　要：直流电弧引起的电气火灾为分布式光伏需要防范的首要风险。本文分析了直流电弧故障的故障类型及其精确识别的影响因素,总结了当前电弧故障相关检测标准及检测方法。基于Matlab搭建了直流电弧检测平台模型并重点研究了直流电弧检测算法中滤波器设计方法。利用直流电弧检测平台模型验证了电弧故障时域、频域特征识别算法有效性。Construction industry is one of the pillar industries in China with intensive energy-consuming and high carbon emissions.The green and low-carbon transformation of construction industry a fatal step towards Carbon Peaking and Carbon Neutrality in China.However,the green and lowcarbon transformation is an uncertain process that combines both opportunities and challenges,requiring multiple forces such as top-level coordinated design,enterprise resource allocation restructuring,and extensive public participation.The absence of any link may have a significant impact on the profitability of the enterprise itself,thereby hindering the achievement of the"Dual Carbon"goal in the construction industry.This paper uses panel regression to evaluate the impacts of green and low-carbon actions on listed companies in the Chinese construction industry,and attempts to clarify its mechanism of action.The research results indicate that Chinese construction enterprises have been significantly impacted by green and low-carbon actions,and after robustness testing,this result still holds true,which can provide reference basis for government decision-making departments and energy conservation regulatory agencies to formulate green and low-carbon related policies.
