Embodiment 1
[0104] Such as figure 1 As shown, the decoupling coordination method for realizing optimal target control based on the voltage and reactive power decoupling criterion described in the present invention includes the following steps:
[0105] 1. Construct the analog circuit according to the rated parameters of the 35kV / 10kV substation
[0106] This embodiment is to simulate a 35kV / 10kV substation, implement V—I Q Optimal target control, the load takes the phase voltage to operate, and the rated parameters of the phase voltage circuit are as follows:
[0107] The no-load phase voltage ratio of the reference gear is; 6.26kV / 20.2kV=0.31;
[0108] The 35KV line impedance is reduced to the 10KV side: R L2 = 0.62Ω, X L2 =5.5Ω(L L2 =5.5 / 314=17.75mH);
[0109] Transformer rated current: I 2N =0.06kA;
[0110] Transformer on-load voltage regulation range: within ±5% V 2N ;
[0111] Rated phase voltage on the load side of the transformer: V 2N =5.78kV, V 2NH =6.07kV, V 2NL = ...
