Energy Management is a universal platform for analysis and optimization of power consumption.

The application allows you to manage and optimize, within the same organization, the various types of energy that it consumes, such as:

  • electricity;
  • water;
  • gas;
  • diesel;
  • compressed air;
  • inert gases.

The process for energy optimization is divided into three phases:

  • Collect
    Collection of consumption by type of energy and consumption areas. For example, for a mall type of energy can be divided into the following areas of consumption: lighting, HVAC, elevators, etc..;
  • Analysis
    After the collection of indicators, they should be analyzed to determine the areas to intervene and to implement the measures and optimization;
  • Optimization
    Implementation of measures to enable energy optimization. The results must be proven on the basis of new collections of indicators.

The Energy Management System, is presented with a modular structure, consisting of a central control unit (PLC), the respective elements of input/output, and servers for storage and processing of information collected.

The central control unit is responsible for the implementation of the algorithms and the collect remote information. In the units I/O information is collected from the field and are sent to the commands.

The platform interfaces with the user through a set of interactive applications for monitoring and handling of their data.

Experience and engineering capability of EGAPI, resulting in an innovative, configurable and scalable platform, suited to different realities of our productive infrastructure.

Electricity

With regard to electricity consumption, one that could be considered as the motivator of this type of energy management system, are considered the following data:

Active Power:

  • Power in peak hours;
  • Energy in full hours;
  • Energy off-peak.

Reactive Power:

  • Issued;
  • Received.

Peak power:

  • Synchronism with the supplier;
  • Contracted tariff period;
  • Scheduling;
  • Control of load shedding.

In this specific case of electricity management, the application provides the following analysis:

  • Diagrams consumption;
  • Diagrams of power;
  • Diagrams tips;
  • Diagrams costs;
  • Simulations billing distributor.

Water

EGAPI developed essential tools for making decisions leading to rationalization of waste in water distribution networks, and thus reduce waste and energy costs, so much so that a large part of the savings can be achieved by simple maintenance actions and network management.

The system Telemetry and Remote management is :

  • Fully Integrated;
  • Comprising 'standard' technology components;
  • Capable of vertical and horizontal growth ;
  • Operating system that provides robustness ;
  • System with open architecture for integration with other systems.

The modules of Energy Management Telemetry and Remote Management for Water Supply Networks includes equipment, software and services.

The system is based on two main layers:

  • UTC 's - Telemetry Units / Remote Management and Communications;
  • Central Monitoring and Management of Water Supply Networks.

The UTC 's are supported by the implementation of the control points PLCs capable of connecting analog and digital devices.

Each of the PLC installed in the control points are connected sensors for obtaining indicators:

  • Counters;
  • Pressure;
  • Residual chlorine ;
  • Level.

Each UTC installed at various control points allow:

  • Reading Sensors and Counters;
  • Calibration of sensors;
  • Temporary data storage (integration periods);
  • Alarm Management;
  • Communications Management (ADSL/GSM-GPRS);
  • Drives analog/digital;
  • Centralized algorithms parameterization;
  • Tele-management with local autonomy;
  • Ability to mimic local manipulation and through consoles industrial.

This equipment presupposes autonomous operation, with the possibility of centralized parameterization. Simultaneously supports two-way communication : wireline (ADSL) and Mobile Network (GSM/GPRS).

Each UTC can be implemented with a industrial touch panel providing a synoptic as well as the possibility of parameterization and calibration.

The front-end Monitoring and Management of Water Supply Networks allows you to display, in real time, the status of each device analysis, as well as the latest figures collected.

It is possible to detect and identify occurrences and the developments in the last hours. The various UTC 's are presented integrated with Microsoft Virtual Earth.

Allows you to set the level of detail, you can have an overview of all devices, as well as a detailed look at a particular area or zone.

For each assay device displayed, and based on the associated image, the analysis of the state is shown. Thus, real-time status display is possible for each device inserted into each UTC .

Web site also offers data mining, aims to analyze the values ​​collected in a given time. It is possible to perform a number analysis on the collected values ​​by:

  • Integration periods;
  • Daily Analysis;
  • Monthly analysis.

Energetic Audit

The Energy Audit module enables, in a simple and clear way, to query the process variables connected to the system:

  • State of the cargo;
  • History consumption;
  • History of alarms and events.

The audit is dependent on the collection of counters, strategically installed in the organization. Data collection may be central or local:

Collection site:
Elementary configuration for an installation, which enables the implementation of the management system of one or more counters on the local ethernet.

Central collection:
The system was developed to withstand the most demanding and complex settings, such as sets of facilities, geographically dispersed, with independent settings, but need to consolidate information for centralized management and monitoring.

Accountants/types of energy, as well as areas to monitor and to be accounted and the periods after which the data is collected into to the database, are parameterized in the application software.

The data collected in each year is available for analysis, keeping or not, according to customer needs, historical collections prior to this time interval.

Is possible to characterize and configure facilities, tariffs associated with these facilities and also data analysis reports. The simulation of tariff is also contemplated in the application.

Is it possible to narrow the analysis to only one facility.

The implementation of a central database, with the consolidation of data on N sites, is supported by the software .

For example, in a network of manufacturing facilities, services or premises, the data centrally collected, from all sites, is available for viewing and reporting where you can make comparisons between facilities in the same business area.

Control and Time Schedule

The control of the Maximum Allowable, allows you to control the maximum allowable tip in each 15-minute. This period is synchronized with the integration period of the energy supplier.

Control is slashing loads whenever needed, usually non-essential loads, and according to a sequence governed by priority, previously set by the user, in the computer system. The proceeding reconnection are in the same reverse order.

The option of Load slashing, existing functionality in the power supply, is a typical need in industrial oriented facilities.

With load slashing, it is intended that a facility may never be achieved ' peaks ' of consumption, eg the simultaneous start of various equipment , for overcoming certain limits hired , would cause an indexation of the tariff to a higher echelon .

Thus, the implementation of the load slashing management allows the same PLC, which collects and records the consumption, to carried out, simultaneously, priorities managed by the scope of this consumption peak, so that the maximum never be achieved with consequent benefits in the management and cost.

The Time Schedule allows for forward planning, shedding sequences and turn on or off of more than 30 loads called ON / OFF .

In this system is contemplated the implementation of PLC's. PLCs are highly modular, highly functional and with a small footprint.

The family of CPUs, consists of three basic models , only differing in the number of I / O subject to control , program memory and data memory .

All have a peripheral port and an RS-232C. Also incorporate a real time clock. Its processing speed stands at 100 nanoseconds (25 MHz).

Software of Management and Analysis

The application was designed so that all components of the system are configurable to withstand the inevitable dynamics of facilities.

The control and monitoring configurable by user, allowing the division of areas and peripheral areas indexed to respective data acquisition.

Thus, there are settings in the information system for each of the supported facilities, their sectors, counters and PLCs, energy type, etc...

  • PLC : A PLC is characterized by the IP address associated with it by a name and by number of entries available in it.
  • Counters : A counter is characterized by the type of energy that reads from the PLC and the PLC that is associated. The system supports setting up virtual counters, counters whose values ​​are recorded and produced from sums or subtracts on one or more physical timers in the installation.

A simple mouse navigation over each of the area displays the current time consumption for each type of energy.

Can also be visualized the time remaining to the next integration period(s) PLC (s).

Access to the records is simple and objective.

All content can be found in table or graph for further analysis.

All information may be subject to 'filters' chronological (day , month, year ), with comparative graphical analysis of consumed values​.

This module proves to be a fast and efficient method for detection of 'deviations' in the consumption pattern.

Are still available to the user 'tools' for simulations. These prove to be a valuable auxiliary in conference bills and essential for selecting the best configuration of tariffs against the consumption of each installation.

The installation of this system has other potential content providers as other management tools. For example, the detailed record of consumption of certain equipment may be implemented in the database that provides concrete data and objectives for the planning and implementation of preventive maintenance.
