AD916CC電纜
港口停靠船只使用岸電電源供電,具有三大優(yōu)點(diǎn):
1、電屬清潔能源,減少對大氣的污染;
2、供電網(wǎng)絡(luò)更加穩(wěn)定,提高供電質(zhì)量;
3、用電與燃油相比,更加經(jīng)濟(jì)合理。在遠(yuǎn)洋船舶的輔助供電系統(tǒng)中,由于軸帶發(fā)電機(jī)的原動(dòng)力取自燃燒劣質(zhì)低價(jià)燃油的主推進(jìn)柴油機(jī),其運(yùn)行效率及經(jīng)濟(jì)性遠(yuǎn)高于燃燒輕油的專用發(fā)電機(jī),因此,軸帶發(fā)電機(jī)系統(tǒng)占有日益重要的地位。
AD916CC電纜由于船在航行時(shí),主機(jī)轉(zhuǎn)速根據(jù)需要會經(jīng)常調(diào)節(jié),與之直接相連的軸帶發(fā)電機(jī)轉(zhuǎn)速也會隨著變化,因此需要對輸出電源進(jìn)行恒頻恒壓控制;同時(shí)在停泊或靠岸等類似工況時(shí),由于主機(jī)停止工作,軸帶發(fā)電機(jī)也停止工作,因此,船舶仍需裝設(shè)備用柴油發(fā)電機(jī)作為輔機(jī)以提供必要的電力,并且備用柴油發(fā)電機(jī)與軸帶發(fā)電機(jī)之間必須無縫切換。藍(lán)海華騰逆變器與軸帶發(fā)電機(jī)組成的恒頻恒壓發(fā)電機(jī)系統(tǒng)實(shí)現(xiàn)了與備用柴油發(fā)電機(jī)的并網(wǎng)控制,可達(dá)到輸出電壓穩(wěn)定、諧波低、并網(wǎng)沖擊電流小的功能。這是逆變器在船用電源領(lǐng)域的一個(gè)新方案,既有軸帶發(fā)電機(jī)的節(jié)能效果,又有穩(wěn)定電壓輸出,給船上的用電設(shè)備實(shí)現(xiàn)不間斷供電船用恒壓恒頻電源,其負(fù)載是船上的所有用電設(shè)備,應(yīng)選用藍(lán)海華騰V5-H-C9電源專用逆變器,給船上的用電設(shè)備進(jìn)行不間斷供電,選擇逆變器功率時(shí),為了使用的安全穩(wěn)定建議留有一定的余量。電壓跟隨性好,環(huán)流電流小;
輸出電壓穩(wěn)定;
輸出正弦波可快速追蹤工頻電壓、頻率、相位角,實(shí)現(xiàn)快速并網(wǎng);
逆變器的輸入頻率范圍廣,能適應(yīng)軸帶發(fā)電機(jī)頻率變化。
并網(wǎng)實(shí)際效果
電壓相位、幅值越接近重合并網(wǎng)時(shí)環(huán)流電流越小,滿足現(xiàn)場應(yīng)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,
