Smart Meter- The In­dian Sce­nario

The In­dia Power Sec­tor is chal­lenged by power loss dur­ing trans­mis­sion and dis­tri­bu­tion. The In­dian Elec­tric­ity mar­ket is fac­ing a se­ri­ous chal­lenge in pro­vid­ing con­tin­u­ous power sup­ply to con­sumers. By im­ple­ment­ing pre­paid smart me­ters in the Res­i­den­tial seg­ment Util­i­ties can ben­e­fit by col­lect­ing the cash be­fore con­sump­tion. By us­ing the fea­ture of “Re­mote Dis­con­nect” func­tion­al­ity, Util­i­ties can re­move a cus­tomer who has not paid the bills. Con­sumers are able to mon­i­tor their en­ergy con­sump­tion pat­terns and also watch their us­age costs on an in- home dis­play unit and as a con­se­quence they change their con­sump­tion pat­terns. Con­sumers also adapt to use en­ergy when it is cheaper as per the dif­fer­ent schemes of­fered by the util­i­ties. Also the in-bu­lit Tam­per con­trols fea­tures in smart me­ters fa­cil­i­tate the util­ity to power theft. The con­sumer’s en­ergy us­age pat­terns are an­a­lyzed to de­tect un­ex­pected con­sump­tion pat­terns, and can in­di­cate a po­ten­tial theft. The smart me­ters spec­i­fi­ca­tion in­cludes 6LowPAN, IEEE802.15.4/15.4g pro­to­cols and DLMS on ap­pli­ca­tion layer for com­mu­ni­ca­tion... With DLMS as a stan­dard ap­pli­ca­tion pro­to­col smart me­ters will in­cor­po­rate any fu­ture com­mu­ni­ca­tion tech­nol­ogy mod­ule.Smart me­ter­ing is the key fo­cus from gov­ern­ment and the state util­i­ties are fo­cus­ing on smart me­ter­ing to im­prove grid in­fra­struc­ture.

Smart grid in In­dia

Smart Grid in In­dia is be­com­ing the key ap­pli­ca­tion in In­dian power sec­tor. Smart me­ters will help to over­come the chal­lenges in the power sec­tor as they will en­able util­i­ties to ac­cess en­ergy con­sump­tion data from re­mote with­out man­u­ally read­ing the meter. It will help in man­ag­ing the power sup­ply dis­tri­bu­tion from re­mote and it will ben­e­fit the con­sumers to mon­i­tor and re­duce their power con­sump­tion re­motely as it will pro­vide real time ac­cu­rate power con­sump­tion data. This data can be ac­cessed fre­quently as re­quired and also avail­able in the con­sumer premises on In-Home dis­play unit. So the com­mu­ni­ca­tion fea­ture of the smart meter pro­vides the util­ity to man­age power load and re­duce losses. De­pend­ing on the load re­quire­ment and by con­stant mon­i­tor­ing of the load of a par­tic­u­lar area, the util­i­ties can im­ple­ment the dif­fer­ent tar­iff plan for that area to man­age peak hour’s de­mands. Also Smart me­ters will help to check the theft, power pil­fer­age and mon­i­tor the qual­ity of power sup­plied to the con­sumers

Com­mu­ni­ca­tion Stan­dards in Smart Me­ter­ing

PLC is by far the most com­monly adopted com­mu­ni­ca­tion tech­nol­ogy for smart me­ter­ing, with more than 50 mil­lion in­stalled points just in Europe, thanks to com­mu­ni­ca­tion proven re­li­a­bil­ity and lower CAPEX and OPEX fig­ures com­pared to other tech­nolo­gies. Among mul­ti­ple avail­able PLC tech­nolo­gies, Euro­pean Com­mis­sion has se­lected “Me­ters and More”, “PRIME” and “PLC-G3” as the most suit­able stan­dards for Smart me­ter­ing roll-outs. Europe is one of the coun­tries with the largest Power Line Com­mu­ni­ca­tion based smart me­ter­ing pro­grams run­ning on field and one of the most ad­vanced in terms of reg­u­la­tions and stan­dards frame­work guide­lines. This ex­pe­ri­ence is a valu­able as­set for all coun­tries out­side Europe who are ap­proach­ing smart me­ter­ing im­ple­men­ta­tions and are look­ing for a cost­ef­fec­tive, re­li­able, in­ter­op­er­a­ble and fu­ture-proof mas­sive de­ploy­ment. For smart meter to data con­cen­tra­tion “last mile“con­nec­tiv­ity, “OPEN meter” pro­ject se­lected Power Line Com­mu­ni­ca­tion (PLC) as the most suit­able tech­nol­ogy. Among sev­eral PLC tech­nolo­gies and spec­i­fi­ca­tions an­a­lyzed, in­clud­ing both nar­row-band and broad-band tech­nolo­gies, only three open com­mu­ni­ca­tion spec­i­fi­ca­tions have been se­lected as able to sat­isfy the AMI de­fined ar­chi­tec­ture and re­quire­ments: “Me­ters and More” (then pub­lished as CENELEC CLC pr TS 50568-4 stan­dard), “PRIME” (then pub­lished as CENELEC CLC pr TS 50567-1 stan­dard and ITU-T G.9904) and “G3-PLC” pro­to­cols (then pub­lished as CENELEC CLC pr TS 50567-2 stan­dard and ITU-T G.9903).

Our new plat­form STComet that is com­plete meter sys­tem on chip. STCOMET is a de­vice that in­te­grates a power line com­mu­ni­ca­tion (PLC) mo­dem, a high­per­for­mance ap­pli­ca­tion core and metrol­ogy func­tions. STCOMET SoC has be­come one of the first two ICs to com­plete the new G3-PLC™ cer­ti­fi­ca­tion pro­gram an­nounced by the G3-PLC Al­liance in Septem­ber 2014.
