<p>The invention relates to a method and installation for monitoring and zonal managing of the energy of natural gases in distribution networks. According to the invention, the method consists in collecting, in some units for concentrating data from some flow computers related to inlet adjusting and measuring stations, from some flow computers and PTZ convertors related to some delivery adjustment and measuring stations and from some natural gas composition analyzers, followed by applying a unique time mark supplied by the geostationary satellite system for GPS services to all the collected data, memorizing the thus marked data in some local databases of the local data concentrators, the marked and memorized data being then transmitted to a central calculation unit where there is checked the completeness of all data collected and entered in the central unit data base, in which case there is calculated the caloric power and composition of natural gases for all the local delivery stations and it is memorized, and in the case the data are incomplete, a data restoration or substitution is initiated, followed by performing the corresponding calculations. The monitoring installation claimed by the invention consists of some local data concentrators (CD) communicating with a central calculation unit (UCC) by means of some modems (MGPRS) and some antennas (AGPRS), in a GPRS network, an interface (APN) for the bidirectional control of GSM-GPRS access to the Internet, synchronizing all the calculation equipments related to the gas conduit network subjected to monitoring, being performed by means of some GPS modems (MGPS) for connecting through an antenna (AGPS) to the GPS network, the data concentrators (CD) being connected in source points (S) for gas inlet into the network with inlet and measuring adjustment stations (SRMS), and in the points of delivering (L) the gases to the consumers, with delivery adjustment and measuring stations (SRML).</p> |
