2. Tsarin Tsarin
Tsarin gwaminatin da aka saba amfani da shi ta hanyar microprocessor ya ƙunshi manyan matakai uku:
Tsarin Sarrafawa: Babban injin sarrafa dabaru ne mai inganci wanda masana'antu ke iya tsarawa (PLC) ko kuma wani na'urar sarrafa dijital ta musamman. Yana aiwatar da algorithms na sarrafawa, yana sarrafa abubuwan da aka shigar, kuma yana lissafin siginar fitarwa. Masu sarrafa abubuwa masu yawa (sau da yawa a cikin tsarin jiran aiki mai zafi) sune mizani ga masana'antu masu mahimmanci don tabbatar da aiki ba tare da katsewa ba.
Matakan Aunawa & Shigarwa: Wannan ya haɗa da na'urori masu auna sigina masu mahimmanci: saurin injin turbine (wanda aka auna ta hanyar na'urorin maganadisu ko na'urorin mita), matsayin na'urar jagora ko allura (ta hanyar na'urorin transducers na matsayi), fitarwar wutar lantarki, da mitar grid. Hakanan yana karɓar maki daga ikon kula da injin ko mai sarrafa grid.
Layer na Aiki da Wutar Lantarki: Siginar sarrafa dijital da aka ƙididdige ana canza ta zuwa siginar analog kuma ana ƙara ta ta hanyar mai canza wutar lantarki (yawanci bawul ɗin servo ko bawul ɗin da ya dace). Wannan bawul ɗin yana sarrafa kwararar mai ta hydraulic zuwa ɗaya ko fiye na masu kunna wutar lantarki (silinda servo) waɗanda ke motsa vanes na jagora na turbine, ruwan wukake masu gudu (a cikin turbines na Kaplan), ko allura (a cikin turbines na Pelton).
3. Fasahar Sarrafa Cibiya
Wayo na gwamnan dijital yana cikin tsarin sarrafa bayanai da aka aiwatar ta hanyar software.
Kula da PID: Tsarin daidaitawa-haɗin kai-tsaye ya kasance ginshiƙin tsari. Mai sarrafa bayanai na microprocessor yana ba da damar daidaitawa mai zaman kansa, daidaitacce, da daidaitawa na sigogin P, I, da D don nau'ikan ayyuka daban-daban (misali, farawa, grid mai keɓewa, haɗin babban grid).
Dabaru na Sarrafawa: Gwamnonin zamani galibi suna haɗa da dabarun zamani:
Kula da Dabaru na Adaptive/Fuzzy: Yana daidaita sigogi ta atomatik don halayen injin turbine marasa layi a ƙarƙashin yanayi daban-daban na kai da kwarara.
Kula da Ra'ayoyin Jiha: Yana inganta kwanciyar hankali da amsawa ga tsarin hydraulic mai rikitarwa tare da dogayen penstocks.
Ra'ayoyin Sau Biyu da Ƙarfin Aiki: Ana amfani da su don haɓaka rage nauyi yayin ƙin ɗaukar nauyi da kuma abubuwan da suka faru na ɗan lokaci.
4. Muhimman Ayyuka
Bayan ƙa'idar saurin gudu ta asali, masu tsara dijital suna ba da cikakkun ayyuka:
Gudanar da Yanayin Aiki: Sauyawa mara matsala tsakanin Gudanar da Sauri (don raba grids ko farawa), Gudanar da Wutar Lantarki (don aika grids da aka haɗa), da Tsarin Ruwa/Gudu (don ban ruwa ko tsarin kwararar kogi).
Jerin Farawa & Kashewa: Jerin shirye-shirye masu sarrafa kansu gaba ɗaya, waɗanda za a iya tsara su don hanzarta turbine mai santsi da aminci, daidaitawa, da tsayawa.
Kariya & Gano Cututtuka: Ci gaba da sa ido kan kai, yin rikodin kurakurai, da kuma martanin kariya (misali, rufe ƙofa cikin sauri idan aka gano saurin gudu, komawa ga tashoshin madadin).
Sadarwa da Haɗaka: Tallafi ga daidaitattun ka'idojin masana'antu (IEC 61850, Modbus, PROFIBUS) yana ba da damar haɗa kai cikin tsarin SCADA (Sarrafa Kulawa da Samun Bayanai) na masana'antar da kuma babbar hanyar sadarwa ta sarrafa grid.
Inganta Aiki: Siffofi kamar Matattu Zone diyya don gogayya ta inji da daidaitawar Gain mara layi suna inganta ingancin sarrafawa a duk faɗin kewayon aiki.
5. Fa'idodi akan Tsarin Gargajiya
Fa'idodin gwamnoni masu tushen microprocessor suna da yawa:
Babban Daidaito & Kwanciyar Hankali: Sarrafa dijital yana kawar da drift da dead-band da ke da alaƙa da haɗin injina, yana ba da damar sarrafa mita mai daidaito sosai (±0.1% ko mafi kyau).
Sauƙi & Sauƙin Sauƙi: Ana iya sauya dabarun sarrafawa da sigogi cikin sauƙi ta hanyar software ba tare da canje-canjen kayan aiki ba, wanda ke ba da damar ingantawa don takamaiman yanayin shafin.
Ingantaccen Aminci: Rage lalacewar injina, cikakken bincike, da kuma tsarin gini mai yawa yana ƙara matsakaicin lokaci tsakanin gazawa (MTBF).
Babban Aiki: Yana ba da damar jerin sarrafawa masu rikitarwa, ayyukan grid na taimako (kamar amsawar mita mai sauri), da kuma yin rajistar bayanai don nazarin aiki.
Sauƙin Kulawa & Gwaji: Ana sauƙaƙa gano lahani, kuma hanyoyin kwaikwayo suna ba da damar yin gwaji mai zurfi ba tare da amfani da injin turbine na gaske ba.

Gwamna mai tushen microprocessor shine mafita ta ƙarshe ga ikon sarrafa wutar lantarki ta zamani. Ya samo asali daga mai sarrafawa mai sauƙi zuwa wani yanki mai hankali, mai sadarwa mai mahimmanci don ingancin masana'antu, kwanciyar hankali na grid, da kuma samar da muhimman ayyukan grid.
