公司現(xiàn)有電力調(diào)度數(shù)據(jù)網(wǎng)已建成投運(yùn)，具備實(shí)時(shí)通道和非實(shí)時(shí)通道，現(xiàn)有總調(diào)相關(guān)遙測(cè)、遙信數(shù)據(jù)通過(guò)實(shí)時(shí)通道將浮點(diǎn)值上傳至地調(diào)，非實(shí)時(shí)通道處于空閑狀態(tài)，即只要有電度數(shù)據(jù)接入，即可通過(guò)該通道將準(zhǔn)實(shí)時(shí)電度數(shù)據(jù)上傳地調(diào)電量采集主站系統(tǒng)。
現(xiàn)有電力調(diào)度數(shù)據(jù)網(wǎng)示意圖見下圖1。
按地調(diào)要求，需要接入的電量數(shù)據(jù)有總降進(jìn)線、發(fā)電機(jī)出線等，目前公司總降進(jìn)線、發(fā)電機(jī)出線、熱電出線電度表RS—485通信口接線示意圖，見下圖2。
圖2中，每塊電度表有兩個(gè)RS—585通信口，分別被綜合自動(dòng)化系統(tǒng)、iES—E50電能量遠(yuǎn)方終端、無(wú)線雙向終端占用：電度表3、4、5、6、7、8、9、10通信口1及電度表1、2通信口2通過(guò)屏蔽RS485通信線連接綜合自動(dòng)化系統(tǒng)前置機(jī)MOXA串口15通信（DLT-645規(guī)約），電度表3、4、5、6、7、8、9、10通信口2及電度表1、2通信口1與iES—E50電能量遠(yuǎn)方終端通信，電能量遠(yuǎn)方終端通過(guò)撥號(hào)方式連接PCM設(shè)備、傳輸設(shè)備與電業(yè)局計(jì)量中心計(jì)量主站系統(tǒng)通信。
3 電量采集系統(tǒng)的建設(shè)方案debugging function has won the unanimous praise of users, and once again has withstood a strict test in an extremely complex industrial environment. In the hulusu coal washing plant project, the NA400 PLC adopts the distributed structure of Ethernet Remote i/o. The PLC master station is set in the substation of the electrical test building, the PLC substation is set in the distribution room of the concentration workshop, the raw coal bunker substation and the product bunker substation, and the PLC upper computer is set in the centralized control room of the electrical test building. The communication between PLC master station and PLC substation, between PLC and upper computer is through industrial Ethernet, and between PLC and intelligent equipment is through industrial bus. The control and communication interfaces with gas monitoring system, rapid loading station and olefin project are considered, and the reserved interfaces with large chemical fertilizer projects are reserved. S908 optical fiber networking is used between PLC master station and slave station i/o, and Ethernet switch networking is used between master station PLC and control room Project Overview: there are 2 main stations +1 i/o in the semi autogenous grinding electrical building, 1 i/o in the substation, 2 main stations +1
