PADEE Detail Description

PADEE Electric Power Distribution Network Analysis, Design and planning in low and medium voltage based on CAD-CAE-GIS SOFTWARE

This Tool is for Designing, Planning, Operation, Maintenance, Loss Reduction and Inventories in distribution networks systems, it is mostly used by utilities and consultants who work in Electric Power Distribution Systems. It analyzes the medium voltage, Low voltage and Customers systems under integrated and common software

The Software takes the electric data directly from distribution networks maps in CAD and analyzes them (running a load flow analysis), placing the results directly on maps automatically and interactively.

Power Distribution Networks Analysis Program (PADEE 2023) software uses Autocad, BricsCad or ZWCAD Front - End, over Windows (WIN 7, WIN 8, Win 10 or Win 11) to perform load flow calculations, analysis on electric distribution networks.

It is also an information system to support works and Customer location and behavior. It uses CAD - CAE (Computer Aid Design) - (Computer Aid Engineering) and GIS (Geographic Information System), technology so all activities are carried out graphically, inside the electric feeder map in CAD.

Inputs for calculations are taken automatically and the output is presented over the map, with color graphics or signs that highlight the most relevant aspects of the analysis. The detailed results can be printed out.

This software make load flow calculations in medium and low voltages systems, and link customers directly to medium voltage substation, so customers can be located geographically and traced up to theirs feeder's or substation's in forward or backward queries.

The next figure presents PADEE's basic modules.

There are some other higher end modules that require custom made interfaces for each individual Utility, which must be made at additional cost. These modules are shown in the following figure.

All these packages or modules are described below:

• Intelligent Maps Program (IMP). Contains standards symbols (blocks) and layers to make maps and all the drawing. These programs help users to draw maps systematically and standardized making them easily to analysis program to get the input data in an automatically way.
  It has automated libraries, to enter symbols with data error filtering, which aids the maps drawing labor. Also has the user's manuals to explain how everything is done. It introduces the data to later use GIS technology and easily locate every network elements
  
  
• Primary Network Analysis Programs (PNAP). It calculates voltage drop, losses, short circuit levels and reactive compensation optimization on medium voltage feeders. It has intelligent algorithms to build the topology of the circuit based on the graphic conventions or drawing standards without the intervention of users. There is a demo video on this link https://www.padeepro.com/parp_en_mp4.htm
  
  
• Secondary Network Analysis Program (SNAP): Makes voltage drop, losses and load flow but now for the low-voltage distribution network. It also creates additional files to link the customers affected by the disruption of service with the distribution transformer bank outage, parts off feeder or complete feeder outages. See a demo video on this link https://www.padeepro.com/pars_en.htm
  
• Customers Program (CP): Allows the connection of customers or subscribers data to the structures of the electrical system, allowing obtaining the billing data and energy sold, located at each point in the grid.
  It also works as an information system to support the customer's location (applications and claims) and / or routes of meter reading collection, analysis and characterization of energy consumption by loading zone types, and others.
  It uses SQL command to query customer database. This module complies with the first step to smart-meters technology implementation
  
  
• Transformer Load Management Program (TLMP): Has dual function, one is the summation of energy served by a transformer bank, totalized the energy, convert it to demand and get load levels vs the maximum capacity, resulting in an important distribution transformers loading monitoring (TLM) in banks that have no other kind of measurement.
  The other function is let the engineers input a demand measures recorded in the field to verify or establish the conversion factor energy-demand. This option allows a very important analysis for the detection of non-technical energy losses, because compare the billed energy with the theoretical energy dispatched by the transformer bank.
  
• Equipment Information and Photo Program (EIPP): This module allows link any maps element to any multimedia file. For example photos of equipment, measured records, thermo vision videos, diagrams or details, other one-line diagram in other CAD files, etc. It also brings Google maps to have a view of customers type serves by the network, and could find street's name not available in the network maps but are in the Google maps. Please see demo. Sgmap & Street module
  
• Demand Forecast for Short, Medium and long Term Program (DFP): This module helps demand forecast for the grid. Takes the load of regular areas, totalize the demand for distribution transformers of each regular area and produce an Excel file with the loads. The load for each regular area are processed with Excel using whatever mathematical analysis of demand forecasting you prefer, then performs the reverse process. After the mathematical analysis produced the forecast results, the values are incorporated into the network, for each regular area in proportion to the installed capacity.
  The Users Manual presents a typical example using "Land Use Based methodology" to calculate demand forecast, but users can developed other methods with the help of this module.
  The resulting demand file per regular area can be read by Microsoft Excel or another spreadsheet, allowing the user to perform any calculation or using any kind of extrapolation formulas. and then enter back to the network to perform the load analysis.
  
• Overcurrent Protection Coordination Program (OPCP): This module is a tool to draw log-log curves for overcurrent protections coordination. Contains a series of data curves of multiple relays and fuses used for overcurrent coordination, plus the electronic relays. It has special help tools to easily make One-Line diagrams of the system associated with protection study through automated libraries of symbols, and also has simple short circuit levels calculations of the portion of the systems being study.
  
• Automated Topographic profiles drawing and Pole Placing Program (ATPPP): Its function is to calculate and draw the topographic profile for power lines, it use the book's typesetter of the topographic survey and make the draw in CAD (now electronic stations could enter the data automatically). It also offers all the tools, such as catenaries curves for pole's or support structures manual placing.
  This module consists of several programs for each of the sub-activities performed: data capture module of the surveyor's book, module calculation of books, drawing module topographic profile, placement of structures, drawing catenaries, subscriber ID, Automatic Data Collection for the road location, and program for calculating weigh, medium a factitious.

• Budged Calculation Module (COMWIN): This software is been used since 1985, was upgraded for Windows and multi-user. The system helps budgets, analysis of unit prices, valuations of inventories of electrical works.
  
• Interrupts and Operations Program (IOP): This module simulates the transfer of loads when there is a maneuver in the network. It has the tools to quantify the interrupted load during an operation or maneuver and can identify exactly which subscribers are affected by an interruption.
  The system stores the outages and can provide the total time of interruption (TTI) or the total KWH interrupted. Also Presents the length of lines affected and interrupted installed KVA in distribution transformers affected.
  
• Energy Loss program (ELP): This module allows the detection of non-technical losses, making the comparison of the energy dispatched by feeders and billed energy. It presents a few types of calculations and results depending on user needs, such as circuit losses for micro areas, macro areas, etc. Calculate total energy losses, taking into account the total energy imported to the system and the energy sold.

• Distribution Network Maintenance Program (DNMP): This system keeps a record of all the maintenance work done or to be done. It carried out works statistics in a period of time, can determine whether the maintenance work are becoming more frequent compared to earlier periods, and indicate the need for a massive change of some elements in the distribution system.
  The system allows the identification of planned maintenance work that hasn't been done.
• Network Inventory, Public Lighting and Other Services Program (NILOP): This module makes pole inventory database for the electric distribution network, improving the knowledge of the network and provision of purchase of components and materials. Additionally allows discriminate the supports being used by other utilities such as communication services, Cable Tv, lighting and advertising.
  
• Connection with the SCADA Program (CSCP): Performs the interface with the SCADA system, it can display in CAD maps the remote network operations, indicating recloser operation and out of service transformer bank. It can also produce a history of operations and equipment states (open or closed) of reclosers.
• Transformers Bank Totalizer Program (TBTOTP): This module works with energy meters installed on every transformer banks. During the meter reading cycle transformers are include in the reading route as any other customer, then are separated filtering the customer's database to produces an estimate load. Finally it calculates the Utilization Factor of each transformer and colored in red, yellow and green depending on the loading %. It is important to visualize as information management to reduce technical and non-technical losses.

PADEE takes advantage of the important and necessary work needed to keep Electric Distribution networks maps updated, and obtain the input data for load flow studies directly from these maps. The Maps constitute the main database for all the modules or subsystems, because either information or analysis data are taken automatically and directly from the maps as they just have all the information to perform electrical studies. Drawings are prepared with CAD and GIS technology and the maps produce with PADEE can be plotted and interpreted by any personnel or any other software because is a standard way of presenting data of feeders maps. There are no hidden data.

As MAPS are the database that centralizes all the information, they should be standardized and developed under the drawing standard of the utility company, using aids or tools that CAD technology gives us. PADEE has these tools to make a correct use of "layers" and "blocks" of symbols. In addition to make ease standardization, CAD technology incorporates "intelligence" to provide all the information required by engineers to perform network analysis.

Information systems and analysis modules use these data obtained by examining the maps, and took the values and calculations results directly from the drawings prepared on CAD, giving a graphic capabilities such as geographic information system analysis and unmatched high capacity and calculations performed in a few second or minutes.

Hardware requirements are:

1) Windows XP is only supported for Corporative users under special request. For others is no longer supported because it has arrived to his "End of Life"
2) Win XP don't support "https", some modules using GMAP or Gstreet may present a message to upgrade your Internet Explorer version, but it will work fine by now.

Installation needs administrator privileges to enable user's to write on the Windows system directory, Windows registry and program folder. In all cases please download all critical updates from Microsoft

The hardware requirement are rule by CAD software drawings size, not because PADEE Software. Normally computer with CAD software than can handle maps easily, will handle the PADEE software without problems. As simple rule, you must use the CAD version of according with the hardware performance, new CAD Version needs more hardware requirements, but can it can manage bigger maps easily.

All the data can be exported, allowing compatibility with other Power Distribution analysis software.

There has been enough pass evidence to think that PADEE can be ported to newer operating systems based on Windows. OPEN SOURCE, however, needs further development in applications interface to gain strength and a greater degree of standardization that can be easily applied in CAD and other high end software.

Currently BRICSCAD and ZWCAD are working with PADEE, that is CAD software with CAD Consortium technology and lower price than AutoCAD, but it has been detected that AutoCAD run faster in PARP module.
