It raise the viewpoint of equivalent capacitor CT that the capacitor isavariable data with control angle nullchange for TCSC capacitor circuit, and carry out theory analysisand test and verify.It studies the effect of different basicfrequency reactance X L of theTCR to theresnullonancepoint and the controlled range,and the impact to thewaveform and sizeof the current and thevoltage of thethyristor circuit and the capacitancecircuit.It obtains theemulation and dynamicsimulanulltion experiment results,and determines theproportion relation of X C and X L and the selection rangeofthe K .Keywords:TCSC,basicfrequency reactance,TCR,resonance point, equivalent capacitorS E 1 S (59637050)b胡国文null 3 , 1957M 3 , 8 a q , S n Y , ; 1997M b v T BM ,C 1 V Y # 1 3) H , L C , m 6c U bL = L 9 B b - K 3 f , C= 32F L = 2 8null7mH F F TCSC L , 0 ! null! 90 S = L C Q i C b C TCR 7 Y H 220V, C5 Y %V 0 _ 180 , nullV 90 _ 0 ( m 2 U )b B Q H , L UC= 212V, IC= 2null6A, TCR F m 6null TCSC r E F L 1 _ w LFignull6null Relation emulation curves forTCSC basic frequency equivalentimpedanceand inductor L IL = 1null4A, L I = 1null9Ab5 X CT= 81null5#, CT= 39FbN H TCSC uCaiaiLaiC o m 7a U b = Q H , L 5 UC= 165V, IC= 4null8A, IL= 6null5A, I= 3null1Ab5 X CT= 34null4#, CT= 92null7Fb o m 7b U bV = Q H L o A , H o C C b L o e w i bY L N H TCR F X L = 5null46#, F X C= 99null5#, N H K = 4null3 3, | K = 4null3 T(6), i s Y m = 1, 2, 3 9 , 9 V , 90 ! ! 180 ( 0 ! null! 90 ) S = C !crt= 117null2 ( null= 27null2 ) !crt= 159 (null= 69 ) i , m 4 L k C U ( ) H bV 7 V L B C bnullm 7null TCSC uCaiaiLaiC L o ( C= 32F L = 2 8null7mH)Fignull7null Thedynamic simulation waveforms forTCSC uC, i, iL and iC nearby resonantdot ( C= 32F, L= 2 8null7mH)97 17 4 S null V e 1 r E F TCR F 1 _ L nullnull null V m 6a 6bs V A A , C M , XL 9 v , u S | 9 v , P bQ , 5 h l , b u S 9 v , d L = , u e , V P u V e S 9 v b , L = S L = 3, 5, i u v z , u Vv , i V z P , | P TCSC ( ? !V 180 7 S B v S = M , L= e , 9 4 b | a X L , P K B a S = b S L = f L = L | P K 2null2 2null7S = ab V P 90 180 S = , L u u e , 9 C bnull4null XL TCSC # o v l Ynull null Y V L = V F X L v l , TCSC #
