Automation

Security – Performance – Reliability

The System of Automatic Control and Management of Energy Systems coordinates and supports the operation of the mechanical and electrical equipment of an installation.
The central unit of the system consists of the Siemens industrial type PLC, open source, with full scalability and support. The material is widespread in the market and can be supported by any developer, without the user-client being committed to a single company.

The central unit and expansion cards are connected to sensors, controls, imaging modules, communication cards and other more specialized modules, offering the greatest possible operational reliability that currently exists worldwide in the field of automation. It is a system of industrial specifications and requirements, specially adapted to the requirements of the engine room and very user friendly.

Provides a) real-time monitoring of the system (operation of parts, water temperatures, power consumption, etc.), b) direct fault reporting to maintenance personnel (on-site and remote), c) manual management of individual components locally control screen and d) graphical display remotely on a computer.

Through the complete recording of the “behavior” of the system and the individual parts, conclusions can be drawn about its operation and the scenarios of optimal operation can be studied. The software optimizes and adapts the operation of the system to the most efficient conditions.

It is worth noting that in remote installations, such as water supply pumping stations in cities, it is possible to install remote control units, which are connected to the central management point, to give quantities related to supply, quality, failures, etc. Manipulation is done centrally, without going to potentially inaccessible places, a practice that would incur additional costs.

Heat Production Units (heat pumps, coolers, boilers)

The Automatic Control System dynamically defines operating limits, schedule, sequence and rotations. At the same time, it takes advantage of the secondary systems it may have – such as heat recovery – and combines systems cooperation with alternative scenarios.

Solar fields

Following are scenarios of static or dynamic for the full exploitation of energy produced by the sun, controlling the flow and distribution speed in storage containers. Dynamic operating scenarios can be defined depending on the conditions and the activation limits of the alternative heat generating units can be differentiated.

Circulation pumps

Defines their operation, sequence and switching in pump assembly, recirculation characteristics and their operating speed (Inverter).

Electric valves

The Automatic Control System manages the operation of the hydraulic network automatically in order to achieve the correct and reliable operation of the system, but also to be optimized when there is water mixing of different temperatures or cutting branches, geothermal control or recovery.

Terminal units

Controls the operation and operating limits of the terminals with manual central or remote control, while defining static or complex dynamic operating scenarios by placing additional sensors that give more “information” to the system.

Automatic control system

Aeration

It fully manages the operation of the ventilation system with manual central or remote control and can be extended to a more dynamic operation configuration system, based on the optimal energy operation, taking into account – in more complex applications – air quality.

Pumping systems

The operation of the pumping systems is coordinated by the System. This ensures the most efficient control and immediate information – with alarm – on the main panel, but also by sending a remote notification. In addition, the log can be used to infer faults in the installation.

Interface with hotel management systems

The Automation System can work with the hotel management systems and based on the requirements of the use of each space (common or rooms) to control the systems, including cooling-heating and lighting of each facility.

Sewage treatment and treatment plants (biological treatment plants)

The control of the sewage transport pumps and the operation of the treatment units (biological treatment) are done by the system based on individualized or special requirements and operation scenarios.

Water treatment systems

Water treatment plants can now work more dynamically and in full function of the operation of the rest of the system. Also, automation systems are developed and installed within the water treatment units, by the Automation Department of Enpro.

Pressure Groups

Operating scenarios find application in pressure units, especially in units with Inverter pumps. At the same time, the sequence of the pumps or the alternation and definition of the main pump can be optimized. It is noted that, through the recording of the data of the hydraulic network, data of electricity and water consumption, operating and peak consumption hours, as well as safe operation are exported, with error notifications and execution of operation scenario in case of pump failure, so that the unit is not left out of order.
