Description

Naprava za nadgradnjo števca električne energije za delovanje v sistemih naprednega merjenja in pametnih omrežijPower meter upgrade device for use in advanced metering and smart grid systems

Izum se nanaša na delovanje električnega števca v sistemih naprednega merjenja in pametnih omrežij.The invention relates to the operation of an electric meter in advanced metering systems and smart grids.

V tradicionalnih električnih omrežjih je v preteklosti prevladovalo preprosto merjenje porabljene električne energije z mehanskimi ali kasneje, z elektronskimi gospodinjskimi števci električne energije. Porabljeno energijo so operaterji vizualno odčitali na prikazovalniku električnega števca, ob vsakokratnem obisku merilnega mesta. Distributer električne energije je uporabljal energetsko omrežje le za prenos električne energije in v nekaterih primerih tudi za prenos tonskega signala za preklop tarifnih naprav.In the traditional electricity networks, in the past, simple measurement of electricity used by mechanical or, later, electronic household electricity meters prevailed. The energy consumed was visually read by the operators on the display of the electric meter, each time visiting the measuring point. The electricity distributor used the power grid only to transmit electricity and in some cases to transmit a tone to switch tariff devices.

V kasnejšem obdobju, s prihodom elektronskih električnih števcev na trg, so ti omogočili prenos podatkov iz električnega števca v koncentratorje podatkov in naprej v distribucijski center. V tem primeru je običajno šlo le za prenos osnovnih merilnih podatkov o porabljeni energiji v določenem časovnem obdobju, v nekaterih primerih pa tudi za prenos zahtev po časovno urejenem pošiljanju podatkov, iz distribucijskega centra proti števcu.In the later period, with the advent of electronic electric meters on the market, these enabled the transmission of data from the electric meter to data concentrators and further to the distribution center. In this case, it was usually only the transfer of basic metering information on the energy consumed over a period of time, and in some cases, the transfer of requests for timely transmission of data from the distribution center against the meter.

Z razvojem tehnike in različnih tehnologij ter z vzpostavitvijo dereguliranega trga električne energije, so se pri distribucijskih operaterjih električne energije pojavile zahteve po upravljanju porabe energije in po upravljanju delovanja celotnega omrežja. Tako imenovano pametno omrežje električne energije se zato nadgrajuje v sistem standardiziranega prenosa podatkov s ciljem dinamičnega upravljanja stanja omrežja, trenutne in napovedane porabe električne energije, optimizacije prenosa električne energije, zbiranja podatkov o porabi in obračuna porabe električne energije in tako dalje. To med drugim vključuje tudi obojestranski prenos množice podatkov ter prenos ukazov za odklapljanje posameznih delov omrežja.With the development of technology and different technologies, and with the establishment of a deregulated electricity market, the requirements for energy management and for managing the operation of the entire network have emerged with electricity distribution operators. The so-called smart electricity grid is therefore being upgraded to a standardized data transmission system with the aim of dynamically managing the state of the network, current and predicted electricity consumption, optimizing electricity transmission, collecting consumption data and billing electricity, and so on. This includes, but is not limited to, the transfer of data on both sides of the network and the transmission of commands for disconnecting individual parts of the network.

Vzporedno z razvojem pametnega omrežja je potekal tudi razvoj pametnih, sistemskih števcev, ki so sposobni, poleg meritve električne energije, še tarifne obdelave podatkov, prenosa podatkov v različnih komunikacijskih tehnologijah, odklopa napajanja na števec priklopljenih porabnikov, zajema podatkov porabe drugih energentov iz ne-električnih števcev in podobno.In parallel with the development of the smart grid, there was also the development of smart, system meters capable of, in addition to measuring electricity, tariff processing of data, data transmission in various communication technologies, disconnection of power to the meter of connected consumers, capturing data of consumption of other energy from non- electrical meters and the like.

Dejstvo je, da je v električnih omrežjih priklopljenih še vedno veliko enostavnih, električnih števcev, ki zadovoljivo opravljajo svojo metrološko funkcijo, ne omogočajo pa podpore osnovnim funkcionalnostim sistema naprednega merjenja in pametnih omrežij. Zaradi prevelikega nabora funkcij in posledično visoke cene so lahko, za nekatere tržne segmente, sistemski števci predragi in neekonomični.The fact is that many simple, electrical meters are still connected to the electricity grids, which satisfactorily perform their metrological function but do not support the basic functionality of the advanced metering system and smart grids. Due to the large number of features and consequently high prices, system counters may be expensive and uneconomical for some market segments.

Nadgradnja obstoječih elektronskih, števcev električne energije tehnološko ni mogoča zaradi tega ker je ohišje števca zaščiteno z metrološko plombo, in je ta prostor distribucijskemu operaterju nedostopen. Omenjenemu operaterju je dostopen le prostor znotraj pokrova priključnice števca. Poleg tega je nadgraditev električnega števca prostorsko omejena z majhno prostornino električne omarice. Omenjena dostopnost in prostorska razpoložljivost postavlja zahtevo po namestitvi nadgradne naprave v območje ohišja priključnice števca ob zahtevi, da je potrebna zagotovitev izmenljivosti posameznih modulov zaradi različnih zahtevanih funkcionalnosti s strani distribucijskega operaterja električne energije.It is technologically impossible to upgrade existing electronic electricity meters because the meter housing is protected by a metrological seal and this space is inaccessible to the distribution operator. Only the space inside the cover of the meter connector is accessible to the said operator. In addition, the upgrade of the electric meter is spatially limited by the small volume of the electrical box. The aforementioned accessibility and spatial availability necessitates the installation of a superstructure in the area of the meter connector housing, when it is required to ensure the interchangeability of individual modules due to the different functionalities required by the electricity distribution operator.

Izum je po mednarodni klasifikaciji uvrščen v razred H02J 13/00 .According to the international classification, the invention is classified in class H02J 13/00.

Izum rešuje tehnični problem, kako nadgraditi že nameščene enostavne, elektronske števce električne energije v sistemih naprednega meijenja in pametnih omrežij električne energije, na način ki ne bo spremenil arhitekture in osnovne funkcionalnosti števca in bo zagotovil komunikacijo in funkcionalnost prenosa podatkov po omenjenemu sistemu, odklopno funkcijo ter upravljanje s porabo posameznih porabnikov priključenih na odjemno mesto, obenem pa bo zagotovljena izmenljivost modulov ki zagotavljajo te funkcije, celotna naprava pa naj nadomesti prvotni pokrov priključnice električnega števca.The invention solves the technical problem of how to upgrade simple, electronic power meters already installed in advanced switching systems and smart electricity networks in a way that will not change the architecture and basic functionality of the meter and will provide communication and functionality of data transmission according to the said system. and managing the consumption of individual consumers connected to the receiving point, while ensuring the interchangeability of the modules that provide these functions, and the entire device to replace the original cover of the electrical meter connector.

Prvotni pokrov priključnice elektronskega, števca električne energije je plombiran in dostopen samo distribucijskemu operaterju električne energije in ima predvsem funkcijo mehanske preprečitve dostopa do priključitvenih sponk električnega števca. To pomeni, da opravlja varnostno funkcijo preprečitve dotika naprave pod napetostjo, funkcijo preprečitve nepooblaščenega dostopa do priključnih sponk števca in funkcijo zaščite proti prahu in vodi.The original cover of the electronic, electricity meter connector is sealed and accessible only to the electricity distribution operator and has the function of mechanically preventing access to the electrical terminal connection terminals. This means that it performs the safety function of preventing the device from touching the power supply, the function of preventing unauthorized access to the terminal terminals of the meter and the function of protection against dust and water.

Elektronski, gospodinjski števci električne energije so opremljeni prvenstveno z merilnim sklopom, prikazom in komunikacijskim kanalom za prenos osnovnih podatkov o porabljeni električni energiji. Omenjeni komunikacijski kanal je običajno izveden v izvedbi impulznega izhoda, RS232, RS485, optičnega zajema podatkov, tokovne zanke, M-Bus in podobno. Tak način prenosa podatkov ne ustreza komunikacijski zasnovi sistema naprednega merjenja in pametnih omrežij, kateri predvideva naslavljanje in paketni prenos podatkov, kot na primer z objekti COSEM/DLMS. Prav tako, zgoraj omenjeni števci praviloma nimajo vgrajenega odklopnika za odklop odjemnega mesta.Electronic, household electricity meters are primarily equipped with a metering assembly, display and communication channel for transmitting basic information on consumed electricity. Said communication channel is typically implemented in the implementation of pulse output, RS232, RS485, optical data acquisition, current loop, M-Bus and the like. Such a method of data transmission does not correspond to the communication design of the advanced metering system and smart networks, which provides for addressing and packet data transmission, such as with COSEM / DLMS objects. Also, the above mentioned meters generally do not have a built-in circuit breaker for disconnecting the collection point.

Znana je izvedba (SI 22221) pri kateri električni števec krmili odklop/vklop zunaj števca nameščene stikalne enote preko Mbus komunikacijskega kanala. Prednost te rešitve je v tem, da je komunikacijski kanal sočasno na voljo tudi prenosu podatkov iz drugih števcev ali merilnikov, ki so priklopljeni na M-Bus komunikacijski kanal. Pomanjkljivost takšne rešitve je v tem, da stikalna enota nima komunikacijskega vmesnika, ki bi omogočal prenos podatkov po pametnem omrežju ter da nima možnosti krmiljenja porabe posameznih porabnikov, ki so priključeni na odjemno mesto. Nadaljnja pomanjkljivost omenjene rešitve je v ločeni namestitvi stikalne enote izven ohišja priključnice in števca, kar zahteva več dodatnega prostora v električni omarici in ki praviloma ni na voljo.An embodiment (SI 22221) is known in which the electrical meter controls the off / on switch off of the counter of the installed switch unit via the Mbus communication channel. The advantage of this solution is that the communication channel is also available to transmit data from other meters or meters that are connected to the M-Bus communication channel. The disadvantage of such a solution is that the switch unit does not have a communication interface that allows data to be transmitted over the smart network and that it does not have the ability to control the consumption of individual consumers connected to the receiving point. A further disadvantage of said solution lies in the separate installation of the switch unit outside the housing of the socket and the counter, which requires more extra space in the electrical cabinet and which, as a rule, is not available.

Znane so tudi rešitve, ki zajemajo priključitev komunikacijskih in krmilnih enot za različne energente neposredno na ohišje električnega števca. Preko takega komunikacijskega modula se lahko nadgradi delovanje električnega števca v smislu komunikacije po pametnem omrežju in v smislu krmiljenja porabe posameznih porabnikov. Pomanjkljivost te rešitve je v tem, da omenjena enota ne vsebuje odklopnika in ne deluje kot zaključena celota v smislu navedenega tehničnega problema.There are also known solutions involving the connection of communication and control units for various energy products directly to the housing of an electric meter. Through such a communication module, the operation of an electric meter can be upgraded in terms of communication over the smart grid and in terms of controlling the consumption of individual consumers. The disadvantage of this solution is that said unit does not contain a circuit breaker and does not function as a complete unit in terms of the stated technical problem.

V patentni prijavi WO 2007/056878 Al je opisana posebna platforma, ki se namesti na merilno mesto tako, da se ta priključi na električne, energetske vodnike, na omenjeno platformo pa se priključi električni števec. Omenjena platforma vsebuje vgrajeni odklopnik, za odklop odjemnega mesta, kar je uporabno tudi za vzpostavitev breznapetostnega stanja pri zamenjavi števca. Pomanjkljivost navedene rešitve je v tem, da ne vsebuje elektronskega komunikacijskega sklopa za prenos podatkov po pametnem omrežju in tudi ne sklopa za upravljanje porabe porabnikov priključenih na odjemno mesto. Zaradi namestitve omenjene platforme na dno števca, je tudi onemogočen dostop do nje in s tem tudi morebitna zamenjava katerega od modulov.Patent Application WO 2007/056878 Al describes a special platform that is mounted on a measuring point by connecting it to electrical, energy conductors, and connecting an electrical meter to said platform. This platform includes a built-in circuit breaker for disconnecting the pick-up point, which is also useful for restoring a voltage-free state when replacing the meter. The disadvantage of this solution is that it does not contain an electronic communication unit for transmitting data over a smart network, nor does it have an assembly for managing the consumption of consumers connected to the receiving point. Due to the installation of the said platform at the bottom of the counter, it is also impossible to access it and thus to replace any of the modules.

Navedeni tehnični problem je rešen s predlagano napravo za nadgradnjo že nameščenih elektronskih števcev električne energije v sistemih naprednega merjenja in pametnih omrežij električne energije, katera je opredeljena z značilnostmi iz označujočega dela prvega in drugega patentnega zahtevka, podzahtevki pa opredeljujejo variantne izvedbene primere.The aforementioned technical problem is solved by the proposed device for upgrading already installed electronic electricity meters in advanced metering systems and smart grids, which is defined by the features of the identifying part of the first and second claims, and the sub-claims define variant embodiments.

V nadaljevanju, bo izum podrobno obrazložen na osnovi opisa izvedbenih primerov in s pomočjo slik, ki prikazujeta:Hereinafter, the invention will be explained in detail based on the description of embodiments and with the help of figures showing:

sl. 1 shematski prikaz priključitve naprave po izumu na obstoječi elektronski števec električne energije in sl. 2 shematski prikaz funkcijskih modulov naprave po izumu.FIG. 1 is a schematic view of the connection of the device according to the invention to an existing electronic electricity meter, and FIG. 2 is a schematic view of the function modules of the device according to the invention.

Ob nadgraditvi že nameščenega elektronskega števca električne energije za delovanje v sistemih naprednega merjenja in pametnih omrežij, se odstrani prvotni pokrov priključnice števca 1 in se ga nadomesti z napravo po izumu 2, ki poleg zgoraj opisanih mehanskih varnostnih in zaščitnih funkcij, obsega še zgoraj navedeni nabor funkcionalnosti potrebnih za delovanje v sistemih naprednega merjenja in pametnih omrežij.When upgrading an already installed electronic electricity meter for operation in advanced metering and smart grid systems, the original connector cover of counter 1 is removed and replaced by the device of the invention 2, which, in addition to the mechanical and safety and security functions described above, comprises the above set the functionality needed to operate in advanced metering and smart grid systems.

Naprava po izumu 2 je električno priklopljena na priključne sponke 11 električnega števca 1 na eni strani in na energetske vodnike 31 in 32, na drugi strani, kot je prikazano na sliki 1. Energetski vodniki 31 so ničelni vodnik 311 in eden ali več faznih vodnikov 312, ki prihajajo iz energetskega omrežja. Energetski vodniki 32 so ničelni vodnik 321 in eden ali več faznih vodnikov 322, ki gredo proti električnim porabnikom na odjemnem mestu. Komunikacija med električnim števcem 1 in napravo po izumu 2 je izvedena preko komunikacijskega kanala IKK za prenos podatkov, ki poteka med izhodnim komunikacijskim konektorjem 115 števca 1 in vhodnim komunikacijskim konektorjem 215 naprave po izumu 2.The device according to the invention 2 is electrically connected to the terminal terminals 11 of the electric meter 1 on one side and to the power conductors 31 and 32 on the other, as shown in Figure 1. The power conductors 31 are zero conductors 311 and one or more phase conductors 312 that come from the energy grid. The energy conductors 32 are a zero conductor 321 and one or more phase conductors 322 that go toward the electrical consumers at the collection point. Communication between the electric meter 1 and the device of the invention 2 is via a communication channel IKK for data transmission that takes place between the output communication connector 115 of the meter 1 and the input communication connector 215 of the device of the invention 2.

Funkcionalna zgradba naprave po izumu 2 je predstavljena na sliki 2. Naprava po izumu 2 vsebuje stikalni modul 23, modul za zajem in obdelavo merilnih podatkov 24, komunikacijski modul 26, napajalni modul 25 in opcijski modul za upravljanje porabe posameznih električnih porabnikov 27 in modul za zajem podatkov iz drugih neelektričnih števcev. Značilnost naprave po izumu 2 je, da so vsi našteti moduli izmenljivi bodisi da se nahajajo v integriranih sklopih ali posamično, na način da se popolnoma ali delno odpre ohišje naprave po izumu in se zamenja ustrezni modul. Zamenjava modulov omogoča spremembo funkcionalnosti naprave po izumu, kot na primer spremembo komunikacijskega protokola v komunikacijskem kanalu EKK, število električnih porabnikov katerih porabo upravljamo, sprememba tipa in števila ne-električnih števcev iz katerih zajemamo podatke in podobno.The functional structure of the device according to the invention 2 is presented in Fig. 2. The device according to the invention 2 includes a switching module 23, a module for recording and processing of measurement data 24, a communication module 26, a power module 25 and an optional module for managing the consumption of individual electrical consumers 27 and a module for capture of data from other non-electric meters. The feature of the device according to the invention 2 is that all of the above modules are interchangeable, either in integrated circuits or individually, in such a way that the housing of the device according to the invention is completely or partially opened and the corresponding module is replaced. Module replacements make it possible to change the functionality of the device according to the invention, such as a change in the communication protocol in the EKK communication channel, the number of electrical consumers whose consumption is managed, a change in the type and number of non-electrical meters from which we capture data and the like.

Stikalni modul 23 vklaplja ali odklaplja eno ali več faz 312, po posebnih zahtevah pa tudi ničelni vodnik 311, in s tem prekinja energetsko oskrbo merilnega in odjemnega mesta. Ukaz za preklop stikalnega modula 23 se po izumu generira v modulu za zajem in obdelavo podatkov 24, ki je komunikacijsko povezan s komunikacijskim modulom 26. Komunikacijski modul 26 sprejema na eni strani podatke iz števca preko komunikacijskega kanala IKK za prenos podatkov iz konektorja 215, na drugi strani pa je povezan s pametnim omrežjem preko komunikacijskega kanala EKK in z domačim omrežjem preko komunikacijskega kanala DKK. Prenos podatkov po komunikacijskem kanalu IKK običajno poteka v obliki napetostnih impulzov, enosmernega toka, RS232, RS485, M-Bus, optičnih signalov in podobno. Iz komunikacijskega modula 26 naprave po izumu 2 se omenjeni iz števca 1 prejeti merilni podatki prenesejo v modul za zajem in obdelavo podatkov 24. V tem modulu se podatki shranijo in obdelajo. Obdelava podatkov pomeni vsako nadgradnjo osnovnega podatka o porabljeni električni energiji in vključuje na primer izračun povprečja porabe v določenem časovnem obdobju, izračun vršne vrednosti porabljene energije, izračun stroškov porabe po tarifni shemi, generacijo alarma pri • · prekoračitvi porabe ali drugih prednastavljenih vrednostih, opremljanje podatkov o porabljeni energiji s časovnimi zaznamki, vrednotenje pravilnosti podatkov, filtriranje podatkov, oblikovanje podatkov v pakete za nadaljnji prenos po pametnem omrežju in podobno. V modulu 24 shranjeni podatki se na zahtevo s strani pametnega omrežja, po časovni razpredelnici ali kateremkoli vgrajenem algoritmu za odločanje, po izumu posredujejo v komunikacijski modul 26, od koder se pošljejo po enem ali več komunikacijskih kanalih EKK ali DKK, kateri so lahko izvedeni v katerikoli od tehnologij žičnih ali brezžičnih omrežnih povezav.Switch module 23 switches on or off one or more stages 312 and, by special requirements, also a zero conductor 311, thereby interrupting the power supply to the measuring and collection points. The switching command of switch module 23 is, according to the invention, generated in a data acquisition and processing module 24 that is communicatively connected to a communication module 26. The communication module 26 receives data from the counter on one side through the communication channel IKK to transmit data from connector 215 to on the other hand, it is connected to the smart network via the EKK communication channel and to the home network through the DKK communication channel. Data transmission via the IKK communication channel is usually in the form of voltage pulses, direct current, RS232, RS485, M-Bus, optical signals and the like. From the communication module 26 of the device of the invention 2, the measurement data received from counter 1 is transferred to the data acquisition and processing module 24. In this module, the data is stored and processed. Data processing means any upgrade of the basic data on electricity consumed and includes, for example, the calculation of the average consumption over a certain period of time, the calculation of the peak value of the consumed energy, the calculation of consumption costs according to the tariff scheme, the generation of alarms when exceeding consumption or other preset values, data fitting about energy consumption with timestamps, evaluation of data correctness, filtering of data, formatting of data into packets for further transmission over the smart grid and the like. In module 24, the stored data is transmitted on request by the smart grid, according to a time table or any built-in decision algorithm, according to the invention to a communication module 26, from which they are sent via one or more EKK or DKK communication channels, which can be implemented in any of the wired or wireless networking technologies.

Naprava po izumu 2 v posebnem izvedbenem primeru vsebuje modul za upravljanje porabe posameznih električnih porabnikov 27, ki je v bistvu modul z enim ali več krmilnimi izhodi 271, preko katerih naprava po izumu 2, na osnovi ukazov iz pametnega omrežja ali algoritmov modula 24, upravlja s porabo posameznih električnih porabnikov, ki so priključeni na odjemno mesto.The device according to the invention 2 in a specific embodiment contains a module for managing the consumption of individual electrical consumers 27, which is essentially a module with one or more control outputs 271 through which the device according to the invention 2, based on commands from the smart grid or the algorithms of the module 24, by consuming individual electrical consumers connected to the receiving point.

V drugem izvedbenem primeru naprave po izumu 2 je komunikacijski modul 26 nadgrajen z modulom 261 za krmiljenje in/ali zajem podatkov iz podmerilnikov električne energije ali opcijsko priključenih merilnikov porabe drugih energentov, ko je na primer voda, toplota, plin in podobno. Komunikacijski kanal SMU za omenjeno komunikacijo je prilagojen vrsti komunikacije, ki jo uporabljajo priključeni podmerilniki električne energije ali merilniki drugih energentov, kot na primer napetostni impulzi, enosmerni tok, RS 232, RS 485, optični signali, MBus in podobno.In another embodiment of the device of the invention 2, the communication module 26 is upgraded with a module 261 for controlling and / or capturing data from power meters or optional connected energy meters, such as water, heat, gas and the like.
