2 WHO IS MATMOR? Ingenieria y Construccion MATMOR is form in 1998 with 30 years engineering staff experience in Electric Energy Distribution Projects, Transmission and Substations. All these experience was and continuous used in developing software MATMOR also do electric Works inspection and minor construction projects. It also helps clients budgeting, buying and reception electric power equipments and computer hardware and software.

3 ELECTRIC ENERGY DISTRIBUTION NETWORK ANALISYS PROGRAM ( ) is a group of tools in CAD, CAE y GIS to do all calculations and load flow analysis inside the distribution network maps environment. It also strongly support works executions, and customers offices tasks. Information Systems Analysis Systems Work budged

6 Highlights Covers and integrates Planning, Operation, Projects, Commercial and Maintenance areas with a unique and coherent data base easy to visualize Use simple methodologies. Computer Hardware requirement is low. Quick Learning curve More than 300 seats in use Easy to buy for consulting companies and publics utilities companies due to Flex Licenses opportunities

7 Intelligent Map Design (IMP) It use Autocad drawing engine to make network maps easy to draw, share and maintain with a very fast learning curve Take advantage of AutoCAD's layers and symbols

8 Intelligent Maps (IMP ) The information needed to make all kind of analysis is available in networks maps, and these maps are already inside a computer (Autocad drawing), take advantage of this and use the computer to extract the distance, loads, capacities and other data available in the map and transfer into the analysis programs automatically and transparent to Users. Maps Type Streets and parcels Electric Network Equipment Locations One Line Diagrams and schematics drawings This programs use the same visual symbols we had use for many years and but it may be customize to local drawing standards Layers and Blocks to makes maps Drawing Procedures to make intelligent maps Distances, Conductor Sizes, R y X Transformers Capacities, switches, cut-outs and other equipments

9 Selección de as y Símbolos utilizando Menús and Symbols Selection using Menus programs are called and loaded using pulldown menus or icons toolbars. Symbols are selected graphically from specials libraries menus

10 Equipment Information and Photo ( EIPP ) Equipments in maps are linked to image, Excell Data, movie, or any other kind of multimedia documents. As example, pole may be photograph and linked to the network map. With this program you may click the symbol in map and it will deploy the information

11 Primary Network Analysis s ( PNAP ) All analysis are inside the maps. PNAP results are graphics. It use Flags or colors to highlight problems at points or sections. Tabular results is just for detailing results and are similar to older programs.

12 Primary Network Analysis s ( PNAP ) Automatically Feeder COLORED

13 Primary Network Analysis s ( PNAP ) Other Graphical Results

14 - Primary Network Analysis s ( PNAP ) The following analysis may be be performed: -- Load Flow and profiles graphics results (( voltage, loads, losses in in each feeder sections and summaries) -- Capacitor Locations by by minimum loss or or minimum voltage drop criteria. -- Short Circuit calculation, three phase, two phases, two phase to to ground and single phase to to ground. -- Substation placing by by load center criteria.

15 Secondary Network Analysis (SNAP) Calculates operation conditions of secondary network base on customers loads linked to poles and taking data directly form maps. Perform load flow calculation for low voltage network Results are output with a simple diagram as shown on right side figure. Highlights are show directly on map.

16 Customers s (CP) Customer Data is Linked to Poles and Parcels in maps

17 Transformer Load Management ( TLMP ) TLMP obtain transformer loads from low voltage networks, it use the relation made by SNAP and CP to get energy use by consumers. It sum all the energy use by consumers use factor K to get transformer bank total demand. It may reverse the analysis with a instant measure to get estimate energy dispatch by transformer bank, and estimated non technical losses Trafo Nº. Pole Nº Capacity (KVA) Total Energy Load Total (KVA) % Load (KVA) Notes Montly AA x Overloaded AA x AA x Overloaded AA x AA x AA x Overloaded AA x AA x Overloaded BA x Overloaded BA x BA x Overloaded BA x Underloaded BA x Overloaded

18 Demand Forecast ( DFC ) DFC make easy the hard work needed to input the land use data base. It also help to correlate present demand with estimated demands in small areas. May produce small area demand history. Forecast Index

19 as de Coordinación de Protecciones (PCP) Has more than 150 relay type and fuse curves Symbols Library to aid oneline diagrams Curve, CT Dial and TAPS Data Automatic Identification

20 as de Perfiles Topográficos y Diseño de Líneas ( PPTDL ) Take data directly form Topographic Survey Notebook Do the mathematics Draw the topographic profile It has the tools with catenaries curves to manual pole placing. Calculates the exact catenary's conductors curve with the placed supporting structures or poles. Calculates medium span. Weight spam and real parameter, and other.

21 COMWIN PROGRAM ( B.O.M. - WORK BUDGED) Produce the Bill of Materials Work construction units Work Budged and other reports Can run stand alone o work with autocad maps.

22 Energy Losses No technical Losses (ELP ) Distribute dispatched energy proportional to transformer bank demand Compare Dispatched Energy Vs Billed Energy By small area ( square area) By Feeder By distribution transformer By Large areas Permit visual comparison of energy consumption between houses with similar characteristics Green Parcels are consumers with more than 500 kwh monthly, the rest are billing less with unknown reason

23 Inventory, Street Light and other service ( NILOP ) Directly form autocad map or stand alone Pole by Pole inventory and auditing Materials and equipment in bad shape Street Light auditing Pole rent to support other public service like, phone, Cable TV, and others

24 Distribution Network Manintenance ( DNMP ) Directly from autocad map or stand alone Pending Maintenance Report Maintenance Done Report Equipment and Material statistic Problems reports More frequently actions reports

26 Sistema Scada de Información Interface s de Equipos en Pozos (SIP) (PDVSA) The interface shoot events into the network map, to visualize automatic switching events Visualize Status from automatic switching device.

27 Sistema Transformer de Información Bank Totalize de Equipos en Pozos (TBTOTP) (PDVSA) Produce a graphic visualization of transformer banks demand readings and colors marks depending of transformer utilization factors

28 VEHICLE Sistema de LOCALIZATION Información de PROGRAM Equipos en Pozos (VEHLOCP) (PDVSA) Show vehicle position on top of distribution network map in order to improve operation and reduce outages time.

29 Sistema Fault History de Información Location de Equipos en Pozos (PUBFAL) (PDVSA) Locate over the network map historic faults by it s cause, in order to make maintenance plans

30 Sistema Claim de Información Location de Equipos en Pozos (CLAP) (PDVSA) Locate over the network map pending claims, in order to locate branches faults or fault origin. Help a lot in massive events In figure shows an example of possible fault origin

31 Main Characteristic Stand alone or Multiple Licenses or corporative licenses were no limitation on number of users. First version are operating since 25 years ago. have help optimized network planning in rural areas, urban areas, agricultural areas, tourist areas, industrial areas and petroleum areas. Use AUTOCAD as drawing platform. This is the best seller cad software in the world. It may work with online diagram where not maps are available Link High and Low Voltages, and customer analysis in one software.
