Complex originl signls cn be decomposed into number of PF (product function) component, ech lyer of PF is composed of the envelope signl nd frequency modultion function, which contins ll the instntneous mplitude nd instntneous frequency informtion. Further combintions cn get the originl signl time frequency distribution. Using the LMD to detect the hrmonic signl nd the multiple frequency voltge flicer signl in microgrid, The simultion results show tht this Algorithm cn dptively decompose the signl nd highlight the locl chrcteristics of PF dt, the method cn be ccurte nlysis of multi frequency hrmonic distortion signl, interhrmonic signl nd multiple frequency voltge flicer signl. Simultion wveform is not only influenced by "end effect" of smll effect, nd the instntneous frequency is lwys positive. According to the ctul nlysis of trnsformer with multifrequency signl power in microgrid system, using LMD lgorithm nd HHT lgorithm, The result further prove the correctness of the proposed method, which provides the theoreticl fundmentl in new wy for the electricl energy detection in power system. Copyright 23 IFSA. Keywords: Locl men decomposition, Hrmonic, Voltge flicer, Power qulity detection, Microgrid.. Introduction The development of new energy nd renewble energy is n inevitble choice to solve the contrdiction between Chin's energy shortge, energy utiliztion nd environmentl protection. Renewble energy, including wind energy, solr energy, ocen energy, biomss, geothermlbsed distributed micro grid technology is one of the development directions of the electric power industry in the 2st century. Microgrid (microgrid, MG): distributed power, energy storge devices, energy conversion device, lod nd monitoring, protection device pool from genertion nd distribution system, nd this utonomous system is ble to chieve selfcontrol, protection nd mngement [2]. With the expnsion of the depth nd rnge of pplictions of microgrid wor reserch, microgrid power qulity problems is getting more nd more people s ttention. Hrmonics cn be divided into stedystte hrmonic nd timevrying hrmonic, nd there re mny studies for the stedystte hrmonic detection method [34]. Microgrid hrmonic disturbnce signl nd interhrmonic signl is nonliner, nonsttionry signls. Fourier trnsform cn not hndle nonliner, nonsttionry signls, spectrl lege nd fence phenomen lso exist between tretments hrmonic 384 Article number P_57
2 shortcomings [57]; Anlysis of nonliner, nonsttionry signls wvelet theory hs mny limittions, must construct divide strict nd energy concentrtion wvelet bsis; HHT power qulity detection methods chieved good results, but the decomposition of the modl experience using cubic spline interpoltion fitting the envelope signl is esy to pper envelope, owe envelope phenomenon; HHT in the excessive number of "screening" led to the end effect of pollution throughout the dt segment nd the instntneous frequency bsed HHT time frequency nlysis methods often pper to be negtive is physicl phenomen which is difficult to explin [89]. Jonthn Smith proposed new dptive timefrequency nlysis method locl men decomposition (locl men decomposition LMD) in 25 []. LMD timefrequency nlysis method is to decompose the originl signl into series of product function group (the Product Function, PF), the lyers PF by the envelope signl nd pure FM signl is composed of two prts, they contin ll of the instntneous mplitude nd instntneous frequency informtion, the further combintion when you cn get the originl signl frequency distribution. The LMD method hs been successfully pplied to the detection of EEG, the instntneous frequency of the signl extrction nd mechnicl fult dignosis []. This is the first time locl men decomposition (LMD) pplied to the power system micro grid hrmonic disturbnce signl nd interhrmonic signl detection, by simultion experiment verify the effectiveness of the method. 2. Locl Men Decomposition Principle 2.. Locl Men Decomposition Algorithm Locl men decomposition cn decompose ny complicted signl into number of the PF component which hs certin physicl mening nd, ech PF component by the plin envelope signl nd FM signl integrted. For signl x(, the decomposition step is s follows [34]: ) To determine the signl x( of ll locl extreme point n i. b) Through ech extremum point n i, clculte ny two djcent locl extreme point men m i nd the vlue of the envelope estimte i m i =(n i + n i+ )/2 () i = n i n i+ /2 (2) Connect the djcent locl men point mi nd m i+ with broen line, nd then conduct smooth hndling by using the moving verge method to get the locl men function m (. Connect ech djcent envelope estimte vlues i nd i+ with broen line, nd then conduct smooth hndling by using the moving verge method to get the envelope estimte function (. c) Seprte the locl men function m ( from the originl signl x(, nd obtin the signl H (: h (=x(m ( (3) d) Divide h ( by the envelope estimte function (, Get the FM signl s (: s (=h (/ ( (4) Determine whether the s ( is pure FM signl, the determintion condition is to repet the bove steps for s (, get the envelope estimtion function ( stisfies the (=, nd if not stisfy described nd s ( is not pure FM signl nd then repet n times until s ( is pure FM signl, i.e. s ( the envelope of the estimtion functions stisfy (n +) (=, so: h h h s s s = x( m = s = s m = h = h = h m ( n ) Conditions for itertive terminted: (5) (6) lim = (7) n In prcticl ppliction, in order to void excessive decomposition number, we cn set disturbnce, the itertion will end when  ( +. e) Multiply the itertive process envelope estimtion function, get the envelope signl (: n ( = t = = ( ) (8) f) Obtin the formul (8) in the envelope signl ( nd pure FM signl s ( multiplied, to obtin the originl signl x(, s PF component: PF (= ( s ( (9) The first PF component contins the highest frequency component of the originl signl. g) Seprte PF(T) from the originl signl x( to get u ( s new dt to repet the bove steps, the cycle times until u ( is monotonic function so fr. 385
3 u = x( PF u2( = u( PF2 u = u ( PF ( t ) () As cn be seen from the bove steps, the originl signl cn be reconstructed by u ( nd ll PF components, i.e.: x( = = i PF i + u () Fig.. Structure of typicl microgrid Bsed on the Instntneous Frequency of the LMD Strie By formul (), the signl is decomposed into number of PF component nd, ech PF components represented by the pure envelope signl ( nd pure FM function s(=cosφ(, its frequency f cn be pure FM function s( directly solve, nmely: φ(=rcos(s() () Expnd the formul () nd the derivtive cn be clculted the instntneous frequency of s(, the corresponding component of the instntneous frequency of the PF. s( vlues between ±, if s( vlue is pproximtely equl to ±, ± insted becuse it is derived by the derivtive of the cosine function of the instntneous frequency of the PF. This method of obtining frequency is intuitive nd simple, referred to s "direct method", nd compred to the method of the instntneous frequency of HHT trnsform strie to strie the instntneous frequency of the "direct method" is lwys positive vlue, does not pper HHT negtive frequencies phenomenon. 3.

Microgrids contin nonliner lod nd lot of power electronic equipment, these deflector chrged with the importnt ts of lod switching nd power trnsfer, but its opertion will cuse the grid voltge nd current wveform distortion, cuse hrmonics nd interhrmonics pollution. Nonliner lod current of mplitude, phse, nd wveform chnges, nd contins lrge number of hrmonics nd interhrmonics ingredients. For wind turbines, the voltility of the fns to contribute Fns to contribute due to chnges in wind speed nd wind turbine tower shdow, the fluctution precisely in to be ble to generte the voltge flicer the frequency rnge (below 25 Hz).
