Dan SIMH S, !lau"iu P#P#VI!I

Lucrarea prezint un sistem neconven ional de management al iluminatului stradal, care respect principii specifice conceptuluismart grid. Comandarea i monitorizarea iluminatului stradal se realizeaz cu ajutorul contoarelor cu

functionalit i extinse i software dedicate. Sistemul este o solu ie robust i de cost redus pentru economisirea de energie electric, scurtarea timpilor de defect i

mbunt irea serviciului de iluminat public.

!"e paper presents an unconventional street lig"ting management s#stemt"at observes principles of t"e smart grid concept. Street lig"ting control andmonitoring are performed using meters wit" extended capabilities and dedicated

software. !"e s#stem is an inexpensive, robust solution for saving energ#, s"ortening contingenc# times and improving public lig"ting service $ualit#.
