Law 3/1985, of 18 March, of Metrology, establishes the legal regime of the metrological activity in Spain, regime to which they must submit in defense of the safety, the protection of the health and the economic interests of consumers and users, the measuring instruments, under the conditions to be determined. This law was subsequently developed by various norms of metrological content, among which is the Royal Decree 889/2006, of July 21, which regulates the metrological control of the State on measuring instruments.

This royal decree incorporated into Spanish law Directive 2004 /22/EC of the European Parliament and of the Council of 31 March 2004 on measuring instruments, while adapting the metrological control phases concerning the approval of a model and a primitive verification, in the instruments subject to national specific regulations, to the system of conformity assessment which is regulated in the abovementioned directive, also addressing the development of the the metrological control phases corresponding to the periodic verification and after repair, stages which are not covered by Community legislation.

The additional provision of Royal Decree 809/2006 of 30 June 2006, for which the electricity tariff is revised from 1 July 2006, makes it compulsory for the equipment to be installed for new purposes. Electrical energy supplies for a contracted power of up to 15 kW and those replacing it for new supplies shall allow for the time discrimination of the measures as well as the telemanagement in the technical terms and conditions which establish the Ministry of Industry, Tourism and Trade.

On the other hand, it should be considered what was established in Royal Decree 2018/1997 of 26 December, approving the Regulation of Points of Measure of the Actuals and Transits of Electrical Energy, subsequently modified by the Royal Decrees 385/2002, of 26 April and 1433/2002, of 27 December.

Royal Decree 2018/1997, of 26 December 1997, states in its preamble that the enormous flow of information that the registration of all measures implies is a means of adopting a decentralized communications structure and that, Regulation of points of measurement of the consumption and transit of electric power provides for the possibility for the subjects of the electrical system to voluntarily install the so-called "secondary concentrators", which constitute computer equipment that collect the measurements of the counters of an area and transmit them to the hub main (of the system operator), requiring certain safety and integrity guarantees in the communications to enable the proper operation of the assembly.

Royal Decree 2018/1997, in Article 17, determines that the system operator will define and update the means and protocols in the communications backbone, the characteristics of which will be set out in the specifications. the main concentrator, adding that the choice of such means and protocols will take into account the state of the technology, its evolution and the views and interests of the participants of the measures. It is also available that the protocol used in the access network is unique and standard and that the protocol used for local reading is unique and standard.

Royal Decree 385/2002 of 26 April justifies, in its preamble, the amendment of the provisions of Royal Decree 2018/1997 of 26 December 1997 on the fact that there has been considerable progress in the liberalisation process. of the electricity market, which leads to a considerable increase in the number of consumers. It is then said that if you take into account that the consumption that you make are much smaller, it is necessary to modify the requirements that are fixed to the measuring equipment, adapting them to their specific needs and characteristics. Finally, it is argued that, if it is joined that the large number of consumers could collapse the procedures initially established for a small number of users of great consumption, it is necessary to modify the Royal Decree 2018/1997, of December 26.

In addition, European Directive 2006 /32/EC of the European Parliament and of the Council of 5 April 2006 on the efficiency of the final use of energy and energy services and repealing Council Directive 93 /76/EEC (OJ EU L 111 of 27 April 2006), in Article 13 thereof, lays down the obligation for Member States to ensure that, where technically possible, financially reasonable and proportionate in relation to the potential energy savings, the final customers for electricity, natural gas, district heating and/or cooling and hot water Health care providers receive individual counters at a competitive price, accurately reflecting the actual consumption of the final customer's energy and providing information about the actual time of use.

In the current state of the technology these instruments allow to measure both the active and reactive electrical energy and its generalized installation allows the best management of the distribution network as well as the time optimization of the consumptions.

According to all of this, under the final provision of Royal Decree 889/2006 of 30 June 2006, under which the Minister for Industry, Tourism and Trade may make a number of provisions necessary for his or her application and development, the present order is dictated, which is intended to regulate the metrological control of the State on the active, static combined, active, classes A, B and C and reactive, classes 2 and 3, to be installed in power supplies up to a power of 15 kW of power incorporating devices Time discrimination and telemanagement, in their phases of conformity assessment and in the phases of verification after repair or modification and periodic verification.

For the elaboration of the order, the autonomous communities have been consulted and the mandatory hearing has been carried out for the interested parties. He has also favourably reported the Metrology Board.

This provision has been submitted to the procedure for information on technical standards and regulations, provided for in Directive 98 /34/EC of the European Parliament and of the Council of 22 June, as amended by the Directive 98 /48/EC of 20 July, as well as Royal Decree 1337/1999 of 31 July, which incorporates both directives into the Spanish legal order.

By virtue,

ANNEX II

Telemanagement system

This Annex sets out the requirements for the telemanagement of electrical meters for the measurement of electrical energy.

1. Definitions of terms.

1.1 Telemanagement system.-It is called a system of telemanagement to a system of measurement and two-way communication between the meters and the electrical distributors, which, with the maximum guarantees of integrity and safety, allows remote access to electrical energy meters, with availability of reading, energy management, control of the power demanded and contracted and management of connection/disconnection of supplies and advanced anti-fraud mechanisms, enabling the exchange of information and actions between the systems of enterprises electrical distributors and counters.

1.2 Static electric energy counters with built-in communications. -Contador that, in addition to measuring and recording with reliability and accuracy the active energy in classes A, B and C, up to a power of 15 kW, and reactive energy In classes 2 and 3, it additionally allows to control the power demanded and execute the orders that are transmitted to it confirming its execution.

You must have a software implementation that performs the necessary functionality. It is accessed through a protocol that should include additional security and reliability mechanisms.

1.3 CT Concentrator-Intermediate element between the management and control computing system and the measurement equipment, which allows the management of a limited number of measuring equipment. It has communications with the computer system and with the measuring equipment. They can usually be installed in transformation centers and act with telemanagement functions between the secondary hubs and the counters, managing communications between them.

2. Structure of the telemanagement system.

2.1 System architecture. -The system can be structured into a multi-level hierarchical architecture with the following elements:

Counters: will communicate remotely with CT concentrators via the distribution communications network, primarily by PLC, and locally via optical port, according to UNE EN 62056-21. They shall comply with the established functional telemanagement and hourly discrimination specifications. Counters may exist that communicate through other communication channels directly with the secondary hub, if any, or with the main hub.

CT concentrators: they will communicate remotely with secondary hubs via the access network, using different media; and with the counters, mainly by PLC. Its natural topological location is the center of transformation.

Secondary Hubs: They will communicate with the main hub over the trunk network.

Main Hub.

2.2 System time synchronization. -An hourly synchronization system will be established, preferably based on GPS at the top levels and with a hierarchical structure of synchronization, from the hubs secondary to CT concentrators and counters, by means of supervision and commissioning orders, for compliance with the UNE EN 62054-21 standard. The synchronization chain shall ensure the daily traceability of the clocks to the national time pattern.

2.3 Integrity and security.-The telemanagement system should include mechanisms for access control and registration of unauthorized access events, as well as confirmation of receipt of messages.

3. Technical requirements and functional specifications of the system.

The following functional specifications are set for the telemanagement system:

3.1 Remote reading. -The system will allow reading through communications, among others:

Electrical measures: active, reactive power and maximum powers according to parameterized time discrimination (current values) and those corresponding to billing closures.

Parameterization, active and latent, of rates, calendars, and contracted powers.

Alarms and events.

Counter identification data.

The CT hub will perform a cyclic interrogation, with parameterizable periodicity to all the counters that communicate with it.

Along with this automatic cyclic interrogation task, the system will be able to have the timely access functionality to any counter with priority over the automatic task.

3.2 Remote synchronization. -In each read cycle the date and time of the counters will be checked and synchronized if necessary.

3.3 Remote power control. Cutting and reconnecting. -From higher levels you can send out orders and replace the counters.

Once the order is executed by the counter, the counter will not accept any reconnection of the switch, nor by remote order of the domestic external device if it exists, nor will it allow the interlocking in the face of a manual action external on the switch or automatic reengagement, if some of these functions are available, until you receive a new order to reconnect the top level.

The reconnection function by remote order must comply with applicable regulations for the protection and security of goods and persons.

The inclusion in the same batch of counters of two consecutive years of the date of assessment of the conformity assessment, where appropriate, or of initial installation or, failing that, of the year of manufacture, shall be permitted provided that they are homogeneous for the remainder of the above mentioned data. In this case, the reference age of the batch shall be taken as the oldest date.

For the process of forming the lots and upon justified request by the distributor, the competent public administration may, by reasoned resolution, determine changes in the criteria of homogeneity of the lots for the purposes of their constitution, and establish limitations on the minimum number of counters constituting a lot, as determined in Article 15.4 of this order.

Once the batches are defined, the distributor will submit the following information to the competent public administration:

a) Vendor name and property identifying data.

b) Fundamental counter data identifying the batch:

Reduced inspection.

In turn, a number of reserve counters equivalent to the integer nearest to 25 percent of the number of counters that make up the sample will be selected with each sample.

For a given batch, the counters that compose a sample will be randomly chosen. Upon duly justified request of the distributor, and if the reservation counters are insufficient, additional reserve counters will be extracted.

1.3 Communication of the choice of the sample. -The competent public administration shall make the choice of two samples, 1. and 2. th, for each lot, communicating the result to the distributor, with indication of the serial numbers of manufacture of the selected counters, as well as the identification data of the officially authorised service or body to be carried out.

The competent public administration will randomly select the serial numbers of the counters that will constitute the sample. It shall communicate the result of the choice of the sample to the person responsible for the lot, so that it, under the supervision and control of the competent authority or approved body, removes the counters from the lot to be submitted to the consignment. tests referred to in paragraph 2.2.1 of this Annex, or the verification at the place of installation is applied according to Article 20 of the order.
