چکیده انگلیسی
This paper examines how applicable approximate Jacobian inversions are when implemented in the security analysis simulations of 132Â kV power subtransmission. The complete Scottish 400/275/132Â kV power transmission network was simulated, including the 132Â kV subtransmission network with its high r/x ratios. Both the coupled and decoupled Maclaurin-Newton load flow algorithms were tested. It was proved that high r/x ratios found in the 132Â kV level, five times higher than in 400/275Â kV, have an important influence on convergence and accuracy of the inversion Jacobian load flow algorithms. It was found that the decoupled inversion load flow was applicable for 132Â kV, it converged regularly, but had worse convergence and accuracy characteristics, compared to 400/275Â kV applications, while the coupled inversion load flow was not applicable at all for 132Â kV, it always diverged.
