Sentence examples for line contingencies from inspiring English sources
Design of DSRs to control power flow over transmission lines to alleviate overloads due to load growth under single line contingencies is investigated in this paper.
Evidence shows that a small number of line contingencies in power systems may cause a large-scale blackout due to the effects of cascading failures.
The effectiveness of the proposed approach is demonstrated through voltage security assessment in IEEE 30-bus system and Indian practical 76 bus system under various operating conditions considering single and double line contingencies and is found to predict voltage stability index more accurate than feedforward neural networks trained by back propagation algorithm and AC load flow.
Uncertainties like imperfect scheduling of generators and transmission line contingencies should be conquered and relieved at the earliest to make optimum utilization of available transmission network in order to achieve maximum profits [1, 2].
The design of DSRs to control power flow under N-1 line contingency is performed using this modified 3-phase, unbalanced model.
Future work will include the modeling of load uncertainty as well as transmission line contingency.
They can not start or stop for many reasons and that's why I-and apparently others- are asking whether there is more than just this single line contingency in event of power failure at plants in general.
Presented in this paper is a responsive-reserve scheduling algorithm incorporating constraints imposed by grid security considerations, which include one base case (intact system) and a list of credible contingencies (line out, unit lost, and load growth) of the system.
Cognitive control requires a fine balance between stability, the protection of an on-going task-set, and flexibility, the ability to update a task-set in line with changing contingencies.
However, when these two lines are the contingencies, large amount of active power is distributed on other lines, thereby reducing the maximum of line power flows.
Another IMF initiative that should be commended is the new facility, called CCL (contingent credit line), created to control contingencies that might arise from external shocks.
