Wowongolera wa 505E adapangidwa kuti azigwira ntchito imodzi yokha komanso/kapena kulowetsa ma turbines onse.
makulidwe ndi ntchito. Chowongolera cha turbine iyi chimaphatikizapo ma aligorivimu opangidwa mwapadera ndi malingaliro
kuyambitsa, kuyimitsa, kuwongolera, ndi kuteteza singleextraction ndi/kapena kuvomereza ma turbines kapena ma turboexpander,
oyendetsa ma jenereta, ma compressor, mapampu, kapena mafani aku mafakitale. Mawonekedwe apadera a PID a 505E control amapangitsa kuti ikhale yabwino kwa mapulogalamu omwe amafunikira kuwongolera magawo opangira nthunzi monga kuthamanga kwa turbine, turbine load, turbine inlet pressure, exhaust header pressure, extraction or admission header pressure, or tieline power.

Kuwongolera kwapadera kwa PID-to-PID kumalola kuwongolera kokhazikika panthawi yomwe turbine imagwira ntchito komanso kusamutsidwa mopanda bumpless panthawi yazovuta za zomera, kuchepetsa kupitilira kapena kutsika. Wolamulira wa 505E amazindikira kuthamanga kwa turbine kudzera pamayendedwe ongoyenda kapena othamanga ndikuwongolera turbine ya nthunzi kudzera pa HP ndi LP actuators zolumikizidwa ndi mavavu a nthunzi ya turbine.

Wolamulira wa 505E amamva kutulutsa ndi kapena kukakamizidwa kuvomereza kudzera pa transducer ya 4-20 mA ndipo amagwiritsa ntchito PID kudzera mu chiŵerengero / ntchito yochepetsera kuwongolera molondola kutulutsa ndi / kapena kulowetsa mutu wothamanga, ndikuteteza turbine kuti isagwire ntchito kunja kwa envulopu yake yogwiritsira ntchito. Wowongolera amagwiritsa ntchito mapu enieni a turbine's OEM nthunzi kuti awerengere ma algorithms ake a valve-to-valve decoupling ndi
turbine ntchito ndi chitetezo malire.

Ulamuliro wa 505E umapakidwa mumpanda wolimba wa mafakitale wopangidwa kuti ukhazikike mkati mwa gulu lowongolera lomwe lili muchipinda chowongolera mbewu kapena pafupi ndi turbine. Gulu lakutsogolo la oyang'anira limagwira ntchito ngati malo opangira mapulogalamu komanso gulu lowongolera (OCP). Gulu lakutsogolo losavuta kugwiritsa ntchito limalola mainjiniya kuti azitha kupeza ndikukonza gawolo kuti ligwirizane ndi zomwe mbewuyo ikufuna, komanso oyendetsa mbewu kuti ayambitse / kuyimitsa makina opangira magetsi mosavuta ndikutsegula / kuletsa njira iliyonse yowongolera. Chitetezo chachinsinsi chimagwiritsidwa ntchito kuteteza makonda onse a pulogalamu yamayunitsi. Chiwonetsero cha mizere iwiri cha unit chimalola ogwiritsira ntchito kuti awone zenizeni zenizeni ndi zoyikapo pazithunzi zomwezo, kupangitsa kuti turbine ikhale yosavuta.

Turbine mawonekedwe athandizira ndi linanena bungwe mawaya kupeza zili pa olamulira m'munsi kumbuyo gulu. Ma block terminal osatha amalola kukhazikitsa kosavuta kwadongosolo, kuthetsa mavuto, ndikusintha.
