Safety systems for power supply systems

Safety Systems for Power Supply Systems

For incinerators, photovoltaic systems, wind farms, hydroelectric plants, co-generations plants, and/or other power generation systems uninterrupted operation is crucial: everything would stop without electricity.

Intrusion or vandalism could jeopardize the production of the above plants.

Anti-Intrusion Systems for Energy Sector Companies

Design, planning, installation, putting into service and maintenance of the anti-intrusion and anti-theft alarm systems in compliance with the relevant CEI 79-3 and CEI EN 50131-1 Standards are crucial to create a safety system.

Before designing a system,  possible threats and risks are analyzed.  The costs of possible thefts and damage as well as the location of the real estate, the presence of  controlling workforces and the history of previous thefts or threats are taken into consideration.

For industrial sites we usually offer protection including the monitoring of access points, surfaces and volumes with an external perimeter protection of the industrial site, including fences and areas not built on. We also take the topography and the use of nearby areas into account.

During the design phase we evaluate the possibility of protecting special areas inside the perimeter containing assets which may be of particular importance for the Company.

A second, more internal barrier protects internal buildings and rooms. For rooms requiring a higher degree of safety, such as DPCs, servers and safes, ad-hoc multi-technology systems with smoke dischargers preventing thieves from completing their theft and from damaging the building are used.

Video surveillance services for Energy Supply Plants

Pursuant to the CEI EN 62676 Standard, before designing an industrial video surveillance system we carry out an analysis of the specific requirements of the industrial site and identify which areas require  not only visual monitoring limited to the storage of images, but also  active filming and detecting of incidents by means of the following:

  • automatic real time notification in the case of access into a specific area, with pop-ups, video confirmation and location of the point of interest on the map.
  • Detection of the area by means of thermal video cameras and intelligent video-analysis functions processing images by means of “trespassing” algorithms
  • Visual control of the maintenance personnel having access to the plant
  • Tracking the object of interest by means of an auto-tracking function
  • Mobile detection systems, in particular in the photovoltaic sector. Use of dual (thermal and d/n) optics camera for monitoring the relevant areas.

Within this context, video cameras do not only protect buildings and people, but are also useful tools to:

  • monitor the operating temperature of the systems by means of thermal video cameras and/or multi-technology cameras or drones capable of signaling when the danger threshold is exceeded. Constant monitoring of these technologies  makes it possible to analyze existing problems and collect useful data to improve maintenance and prevention.
  • Creation of a safe environment for the personnel accessing the area or living in it: it is possible to control and monitor the observance of procedures and safety regulations as well as the correct use of the tools and devices made available to the staff.
  • Increased process efficiency: remote control of production lines, visual analysis of functions and processes and control of their correct execution. Very often it is possible to solve problems through remote technical assistance and this reduces the times and costs of on-site maintenance.

Access Control and Presence Detection Systems for Companies working in the energy sector

Companies working in the energy sector have different access levels, depending on the relevant requirements. There are different levels, for example, for owners, for the O&M company and for the various sub-contractors.

It is sometimes crucial that only authorized persons have access to certain areas. This guarantees the reliability of the whole production process and increases the level of safety against possible internal and external attacks.

In general, full-height turnstiles for personnel are provided at pedestrian access points and vehicle barriers with RFID recognition systems are provided for cars and articulated vehicles.

The access control systems offered for the above sector guarantee the following:

  • increased level of safety against potential internal/external/visitors’ attacks with compartmentalization of internal and external areas depending on the title, day, time, etc.
  • Detection of the presence of employees when processing payrolls by means of dedicated terminals for  clock in and clock out reading. As an alternative, it is possible to use access control terminals and interface them with pre-existing systems used for processing payrolls.
  • The use of biometric systems for particularly critical rooms in compliance with the ISO/IESC 19794-5 (ICAO) AND Standards, with Mifare badge reading system, improve the level of safety and reliability of the system.
  • Multi-site centralized management using platforms whose number may be increased (number of users and terminals) depending on the corporate requirements without any impact on system operation.
  • Retrospective tracing of incidents for the safety and statistical purposes.
  • Dematerialization: the documentation concerning privacy and safety measures may be viewed without using paper. Tablets are used for the graphometric signature.
  • Access points can be made more flexible thanks to the use of new technologies for identification and access by means of a smart phone using BLE, NFC and QR codes.
  • Vehicle transit control by means of registration number reading systems, UHF electronic toll collection and APP-BLE systems as well as to control pedestrian access.  This function applies to all types of persons having access to the site (employees, external companies, visitors).
  • Better safety: calculation of the number of people in charge of first aid and fire-fighting or control of the safety data to allow external teams to access the building site.
  • Electronic door keeping: semi-automatic reception based on time bands and remote access control for unattended gates  using IP video intercom systems.

Fire detection systems for Energy Plants

Business continuity in the energy sector is a priority. Interruptions in the data flow can cause very significant losses and damage the image of a Company.

When there is a fire outbreak, a system capable of alerting at an early stage makes it possible to secure the contents of a building. The purposes of the  smoke detection system can be summarized as follows:

01detecting a possible fire outbreak in the shortest time possible

02helping in rapid evacuation and goods removal

Implementation of intervention plans 03

Implementation of protection systems against fire and further safety measures 04

The design, installation, putting into service, operational control and maintenance of smoke detection systems in the industrial sector take place in compliance with the UNI 9795, UNI EN54 and UNI 11224 Standards.

The choice of the detection technology depends on the specific requirements of a certain site. In large logistic areas or warehouses it is often possible to combine several technologies by using linear barriers, point sensors, air analysis chambers and suction systems based on LASER technology to detect smoke particles inside the air taken from the pipelines.

For safeguarding the goods contained in particularly critical rooms, such as the control room, UPS rooms and  SERVER or EDP rooms, we offer a switching off system with dedicated central units in compliance with the EN 12094-1:2003 Standard. This system is capable of managing output modules for activation purposes and input modules for signaling possible failures and/or for the disablement of rooms.

These are particularly critical infrastructures. Therefore specific laws, such as the following, must be applied: DCPREV Note, file no. 1324 of 7/2/2012 for photovoltaic systems, MD 13/7/2011 for generator sets, K.D. 6/5/1940, no 635 for explosive environments, MD 31/7/1934 for mineral oil, circular letter no. 74 of 20/09/1956 for storage areas for LPG tanks,  MD 14/5/2004 for LPG deposits, PD no. 340 of 24/10/2003 for street GPL stations, MD 28/06/2002 for street methane gas stations.
