AD916CC电缆
港口停靠船只使用岸电电源供电,具有三大优点:
1、电属清洁能源,减少对大气的污染;
2、供电网络更加稳定,提高供电质量;
3、用电与燃油相比,更加经济合理。在远洋船舶的辅助供电系统中,由于轴带发电机的原动力取自燃烧劣质低价燃油的主推进柴油机,其运行效率及经济性远高于燃烧轻油的专用发电机,因此,轴带发电机系统占有日益重要的地位。
AD916CC电缆由于船在航行时,主机转速根据需要会经常调节,与之直接相连的轴带发电机转速也会随着变化,因此需要对输出电源进行恒频恒压控制;同时在停泊或靠岸等类似工况时,由于主机停止工作,轴带发电机也停止工作,因此,船舶仍需装设备用柴油发电机作为辅机以提供必要的电力,并且备用柴油发电机与轴带发电机之间必须无缝切换。蓝海华腾逆变器与轴带发电机组成的恒频恒压发电机系统实现了与备用柴油发电机的并网控制,可达到输出电压稳定、谐波低、并网冲击电流小的功能。这是逆变器在船用电源领域的一个新方案,既有轴带发电机的节能效果,又有稳定电压输出,给船上的用电设备实现不间断供电船用恒压恒频电源,其负载是船上的所有用电设备,应选用蓝海华腾V5-H-C9电源专用逆变器,给船上的用电设备进行不间断供电,选择逆变器功率时,为了使用的安全稳定建议留有一定的余量。电压跟随性好,环流电流小;
输出电压稳定;
输出正弦波可快速追踪工频电压、频率、相位角,实现快速并网;
逆变器的输入频率范围广,能适应轴带发电机频率变化。
并网实际效果
电压相位、幅值越接近重合并网时环流电流越小,满足现场应用要求;
A standard 9-pin serial port pin of Kunlun on HMI (tpc1061ti) defines two communication interfaces, one RS232 (COM1) and one RS485 (com2), which are respectively connected to the master station Mitsubishi PLC (fx3ga-24mr-cm) and a Delta PLC (dvp14ss21t) in the operation box.
When the winch works to pull the tramcar up to transport coal, the master station PLC receives the signal that the tramcar reaches a specific position behind the barrier, and sends instructions to the corresponding substation PLC to control the lifting of the corresponding barrier; After the tramcar passes through the barrier smoothly, the master station PLC receives the signal that the tramcar goes up to a specific position in front of the barrier, and sends instructions to the corresponding substation PLC to control the lowering of the corresponding barrier. When the tramcar runs downward, the master station PLC receives the signal that the tramcar has reached a specific position in front of the barrier, and sends instructions to the corresponding substation PLC to control the lifting of the corresponding barrier; After the tramcar passes the barrier smoothly, the master station PLC receives the signal that the tramcar reaches the specific position behind the barrier,
