3. the tidal current computing method of the node power injection models of UPFC five according to claim 2, it is characterised in that：Including Following steps：
(1) UPFC is not added, carries out Load flow calculation under primary condition；
(2) UPFC input information, typing UPFC control targe are read from data-interface；According to the nature of initial Load flow calculation Trend valueWith the Line Flow set in UPFC control targes Obtain node j1And j2Injecting power, that is, obtainAccording to formula (5)-formula (8), calculate V′se1、θ′se1With V 'se2、θ′se2；Further according to formula (1)-formula (4) and formula (9), calculating obtains output information
(3) new state variable is calculated by obtained output valveWith
(4) new input information is obtained again, judges whether new state variable restrains；If not restraining, step (2) is returned to；If receiving Hold back, then UPFC series side controlled quentity controlled variables V is calculated according to output valve and formula (11)-formula (12)se1, θse1, Vse2, θse2, according to formula (10) egress k reactive power Q is calculatedks；
(5) controlled quentity controlled variable V in side in parallel is obtained by formula (13)shAnd θsh。
