AD916CC電纜
港口停靠船只使用岸電電源供電,具有三大優點:
1、電屬清潔能源,減少對大氣的污染;
2、供電網絡更加穩定,提高供電質量;
3、用電與燃油相比,更加經濟合理。在遠洋船舶的輔助供電系統中,由于軸帶發電機的原動力取自燃燒劣質低價燃油的主推進柴油機,其運行效率及經濟性遠高于燃燒輕油的專用發電機,因此,軸帶發電機系統占有日益重要的地位。
AD916CC電纜由于船在航行時,主機轉速根據需要會經常調節,與之直接相連的軸帶發電機轉速也會隨著變化,因此需要對輸出電源進行恒頻恒壓控制;同時在停泊或靠岸等類似工況時,由于主機停止工作,軸帶發電機也停止工作,因此,船舶仍需裝設備用柴油發電機作為輔機以提供必要的電力,并且備用柴油發電機與軸帶發電機之間必須無縫切換。藍海華騰逆變器與軸帶發電機組成的恒頻恒壓發電機系統實現了與備用柴油發電機的并網控制,可達到輸出電壓穩定、諧波低、并網沖擊電流小的功能。這是逆變器在船用電源領域的一個新方案,既有軸帶發電機的節能效果,又有穩定電壓輸出,給船上的用電設備實現不間斷供電船用恒壓恒頻電源,其負載是船上的所有用電設備,應選用藍海華騰V5-H-C9電源專用逆變器,給船上的用電設備進行不間斷供電,選擇逆變器功率時,為了使用的安全穩定建議留有一定的余量。電壓跟隨性好,環流電流小;
輸出電壓穩定;
輸出正弦波可快速追蹤工頻電壓、頻率、相位角,實現快速并網;
逆變器的輸入頻率范圍廣,能適應軸帶發電機頻率變化。
并網實際效果
電壓相位、幅值越接近重合并網時環流電流越小,滿足現場應用要求;
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,
