Kufotokozera Kwambiri
505E ndi chowongolera cha 32-bit microprocessor chopangidwa kuti chizitha kutulutsa kamodzi, kuchotsa / kulowetsa, kapena kulowetsa ma turbines a nthunzi. 505E ndi yokonzeka kumunda, kulola kuti mapangidwe amodzi agwiritsidwe ntchito pazinthu zosiyanasiyana zowongolera ndikuchepetsa mtengo ndi nthawi yotsogolera. Imagwiritsa ntchito mapulogalamu oyendetsedwa ndi menyu kuwongolera mainjiniya akumunda pakukonza owongolera ku jenereta kapena makina oyendetsa galimoto. 505E ikhoza kusinthidwa kuti igwire ntchito ngati gawo loyima kapena itha kugwiritsidwa ntchito molumikizana ndi makina owongolera omwe amagawika.

505E ndi gawo losinthika la turbine la nthunzi ndi gulu lowongolera (OCP) mu phukusi limodzi. 505E ili ndi gulu lowongolera la opareshoni kutsogolo lomwe limaphatikizapo mizere iwiri (24-character pamzere) ndi seti ya makiyi 30. OCP iyi imagwiritsidwa ntchito kukonza 505E, kupanga masinthidwe a pulogalamu yapaintaneti, ndikugwiritsa ntchito turbine/system. Chiwonetsero chamizere iwiri cha OCP chimapereka malangizo osavuta kumva m'Chingerezi, ndipo wogwiritsa ntchito amatha kuwona zenizeni komanso zoyika pazithunzi zomwezo.

Ma 505E amalumikizana ndi ma valve awiri owongolera (HP ndi LP) kuti aziwongolera magawo awiri ndikuchepetsa gawo limodzi lowonjezera ngati pakufunika. Zigawo ziwiri zomwe zimayendetsedwa nthawi zambiri zimakhala kuthamanga (kapena kulemedwa) ndi kuthamanga / kulowetsa (kapena kutuluka), komabe, 505E ingagwiritsidwe ntchito kulamulira kapena kuchepetsa: kuthamanga kwa turbine inlet kapena kutuluka, kutulutsa (kuthamanga kumbuyo) kuthamanga kapena kutuluka, gawo loyamba. kupanikizika, kutulutsa mphamvu ya jenereta, kulowera kwa mbewu ndi/kapena kutulutsa, kulowetsa kompresa kapena kutulutsa mpweya, ma frequency a unit/plant, kutentha kwa ma process, kapena chilichonse chokhudzana ndi turbine process.

505E imatha kuyankhulana mwachindunji ndi makina owongolera omwe amagawika ndi / kapena gulu lowongolera la CRT pogwiritsa ntchito madoko awiri a Modbus. Madokowa amathandizira kulumikizana kwa RS-232, RS-422, kapena RS-485 pogwiritsa ntchito njira zotumizira za ASCII kapena RTU MODBUS. Kulumikizana pakati pa 505E ndi chomera cha DCS kumathanso kuchitidwa kudzera pa intaneti yolimba. Chifukwa ma seti onse a 505E PID amatha kuwongoleredwa pogwiritsa ntchito ma siginecha a analogi, mawonekedwe a mawonekedwe ndi kuwongolera sikuperekedwa nsembe.

505E ilinso ndi izi: Chizindikiro chaulendo woyamba (zolowera maulendo 5), kupewa kuthamanga kwambiri (2 ma liwiro othamanga), kutsata koyambira (kuyambira kotentha ndi kozizira), kuthamanga kwapawiri/kunyamula katundu, kuzindikira liwiro la zero, pachimake. chiwonetsero cha liwiro laulendo wothamanga kwambiri, ndikugawana katundu wolumikizana pakati pa mayunitsi.
