Po petih letih razvoja je organizacija Linux Foundation predstavila izdajo platforme za virtualizacijo SEAPATH 1.0, izdelane ob upo\u0161tevanju zahtev informacijskih sistemov za digitalne podpostaje v energetskih omre\u017ejih. Platforma upo\u0161teva specifi\u010dne zna\u010dilnosti energetskih omre\u017eij, vendar je lahko uporabljena tudi na drugih podro\u010djih, kjer je potrebna visoka zanesljivost. Kodo platforme je objavljeno pod licenco Apache 2.0. Izdaja SEAPATH 1.0 je priznana kot pripravljena za industrijsko uporabo in uporabo v kriti\u010dnih sistemih. Platforma je \u017ee vklju\u010dena v delovno infrastrukturo energetske dru\u017ebe RTE in poteka testno uvajanje v podjetjih GE Vernova, Alliander, ABB, Red Hat in Enedis. <\/p>\n

Za spremljanje, avtomatizacijo, vzdr\u017eevanje in upravljanje porazdelitve energijskih tokov na digitalnih podpostajah v sodobnih energetskih omre\u017ejih so vklju\u010dene specializirane aplikacije razli\u010dnih dobaviteljev, ki jih je predlagano zagnati v lo\u010denih izoliranih virtualnih strojih. SEAPATH implementira platformo za organizacijo dela teh virtualnih naprav<\/a>, virtualizirana aplikacija (vPAC — Virtualized Protection, Automation and Control), ki se lahko izvajajo v realnem \u010dasu.

\"Prva<\/center> <\/p>\n

Za uvajanje vozli\u0161\u010d s hote okoljem SEAPATH sta na voljo dva distribucijska paketa, ki temeljita na Debian GNU\/Linux 12 in Yocto Scarthgap. Platforma ni vezana na dolo\u010deno opremo, ni odvisna od posameznih dobaviteljev in lahko deluje na razli\u010dnih tipih stre\u017enikov<\/a> in strojnih arhitektur. Dovoljeno je izvajanje aplikacij za elektro podpostaje, ki podpirajo standard IEC-61850. <\/p>\n

Odpornost na napake je zagotovljena z uporabo klasterskih konfiguracij z rezervacijo opreme ter s shranjevanjem podatkov in slik virtualnih strojev v porazdeljenem skladi\u0161\u010du, replikiranem na razli\u010dne vozli\u0161\u010da klastra. Posodobitve se samodejno name\u0161\u010dajo z zunanjega stre\u017enika. Upravljanje konfiguracije in administracija se izvajata centralizirano z uporabo koncepta infrastruktura kot koda. <\/p>\n

Platforma je zgrajena na obstoje\u010dih odprtih projektih, za katere je bil pripravljen testni sklop, ki vklju\u010duje ve\u010d kot 700 enotnih testov za preverjanje zanesljivosti. Virtualizacija je izvedena z uporabo hipervizorja KVM in jedra Linux, zgrajenega z mo\u017enostjo PREEMPT_RT za delovanje v realnem \u010dasu. Kot porazdeljena shramba, ki zajema celoten klaster, se uporablja Ceph. Za virtualizacijo naprav se uporablja QEMU, za virtualizacijo omre\u017eja — Open vSwitch. Za upravljanje virtualnih okolij se uporablja orodje Libvirt. Za upravljanje virov v klasterju, zagotavljanje odpornosti in organizacijo interakcij med vozli\u0161\u010di se uporabljata Pacemaker in Corosync. Centralizirano upravljanje infrastrukture in orkestracija virtualnih strojev je izvedena s pomo\u010djo Ansible.
