为研究黄石有轨电车噪声项目对黄石城市区域环境噪声的影响,分析了2019-2023年对黄石有轨电车项目建设前后的噪声监测数据,结果表明:有轨电车项目对沿线各类区域环境的影响主要在施工期;运营期有轨电车占道路车流比例较低,噪声源主要是道路汽车流,交通噪声和沿线敏感点噪声值均符合相应标准;有轨电车项目高架桥的建设导致周边声环境产生了时空变化情况。总体上有轨电车对沿线周边环境的噪声影响较小。建议通过调整黄石市声环境功能区划、优化沿线交通结构、保护噪声敏感点等方式进一步减小噪声的影响。

针对单相光伏并网逆变器在比例积分(PI)调节器的控制下存在电流环难以跟踪电流,且输出滤波电容较大,使得系统不稳定及抗干扰能力差等问题,提出了一种基于比例谐振(PR)与PI调节器的单相并网的双并环控制策略,并搭建了整个单相光伏并网逆... 详细信息

针对单相光伏并网逆变器在比例积分(PI)调节器的控制下存在电流环难以跟踪电流,且输出滤波电容较大,使得系统不稳定及抗干扰能力差等问题,提出了一种基于比例谐振(PR)与PI调节器的单相并网的双并环控制策略,并搭建了整个单相光伏并网逆变控制系统的仿真模型。通过Simulink仿真表明了该控制器应用在整个系统中实现了对并网电流的无静差控制,消除了PI控制引起的相位误差,并提高了系统的稳定性。
