Coordination of directional relays without generating all circuits
A novel method is proposed for obtaining a minimum break point set for computer-aided coordination of directional relays in a power system. This very simple technique uses only fundamental circuits of the system graph for ...
A cut set approach for HVDC converter reliability evaluation
The reliability evaluation of HVDC systems has been gaining much significance in the recent past. A new approach for converter equipment failure analysis is proposed. The AC to DC converter equipment circuit in HVDC systems ...
Necessary and sufficient condition for uniqueness of solutions of certain piecewise linear resistive networks containing transistors and diodes
Equations of the form F(x)=f(x)+Ax=y where f(x)=[f1(x1 ) f2(x2) . . . f n(xn)]T, A is a P 0 matrix and for all i=1,2, . . ., n, fi(xi), are monotonic and piecewise linear but not necessarily strictly monotonic, are studied. ...
Mixed integer programming method for fault diagnosis of linear analogue circuits
Fault diagnosis of linear analogue circuits can be formulated as a mixed integer programming problem. This avoids testing all possible combinations of submatrices of the equations of the network to determine faults
Existence, uniqueness and determination of solution of certain piecewise linear resistive networks
For an equation of the form F(x)=y, it is shown that there is at least one solution for every y if F is eventually P0 passive or the effective Jacobian matrix in all the unbounded regions is a P matrix. In addition to this, ...
A fast algorithm for the generation of fault dictionary of linear analog circuits using adjoint network approach
A method for the generation of a fault dictionary of a linear analog circuit is presented. The method is based on the well-known adjoined network concept. For an (n+1) node network and for an order of n2 faults, the method ...
Delay time sensitivity in nonlinear monotone RC trees
The sensitivity of delay time (time required to achieve a given target voltage) at any node of a nonlinear monotone RC tree is studied using the adjoint-network approach. It is shown that the sensitivity of τ with respect ...
Necessary and sufficient condition for uniqueness of solutions at certain nonlinear resistive networks
It is shown that the Jacobian determinant being nonzero for all values of its variables is both necessary and sufficient for the uniqueness of solutions of a wide class of networks. These networks may contain negative-resistance ...
Signal delay in linear leaky RC mesh/tree
As chip dimensions are reduced, the performance of integrated circuits is limited by the delays associated with the interconnections. For the purpose of propagation delay estimation in digital circuits, these interconnections ...
Delay time sensitivity in linear RC mesh
A generalization of delay time sensitivity in leaky linear RC mesh has been established. In an RC mesh, the spatial monotonicity does not hold, as there is no unique path between the source and any node. Delay time sensitivity ...
