Transmission reliability margin assessment of the Malaysian power system
Proceedings. National Power Engineering Conference, 2003. PECon 2003., 2005Power system deregulation has increased the need for determination of transmission reliability margin (TRM) which is the amount of transfer capability reserved to ensure that the transmission network is secure under a reasonable range of uncertainty in system operating conditions.

Reliability modeling and evaluation of HVDC power transmission systems
IEEE Transactions on Power Delivery, 1994The objective of this paper is to present an improved computational method for evaluating the reliability indices of HVDC transmission systems. The developed models and computational techniques are described. These can be used to simulate the operational practices and characteristics of a system under study efficiently and realistically. This method is

Loadability in composite generation/transmission power-system reliability evaluation
IEEE Transactions on Reliability, 1993An approach to composite (generation and transmission) power-system reliability evaluation that is based on contingency enumeration and on a simulation process to assess the system state is introduced. Using an AC load-flow model, the analysis starts with a nonlinear optimization procedure to determine system loadability.

Maximal network reliability for a stochastic power transmission network
Reliability Engineering & System Safety, 2011Abstract Many studies regarded a power transmission network as a binary-state network and constructed it with several arcs and vertices to evaluate network reliability. In practice, the power transmission network should be stochastic because each arc (transmission line) combined with several physical lines is multistate.

Reliable large acceptance optical fibers for high-power transmission
SPIE Proceedings, 2005Typically, output from high power, diode lasers and arrays must be transported to a final application/treatment site, whether the application is industrial, military or medical. Many demands are placed on optical fibers to couple the laser output into their structures and to transmit the power to the application site. All silica fibers become much more

Bayesian spatial reliability model for power transmission network lines
Electric Power Systems Research, 2019Abstract The paper is devoted for the problem of assessment of the dependence of power transmission lines outages on the geographical position in the network. Authors present the model based on Poisson–gamma random field for the purpose of capturing the information about the strength of correlation between the power transmission network outages and ...

Reliability evaluation in power-system transmission planning: practical considerations
IEEE Transactions on Reliability, 1988In the reliability algorithm based on the maximum-flow minimum-cut technique together with the decomposition principle, the generation of the state space for purposes of classification requires a large amount of memory. A state-space truncation algorithm which reduces the number of states while maintaining accuracy within specific limits is presented ...

HVDC transmission system models for power system reliability evaluation
IEEE WESCANEX 95. Communications, Power, and Computing. Conference Proceedings, 2002High voltage direct current transmission (HVDC) systems are finding increased use for long distance transmission of electrical energy from remote hydro electric generating stations to the load centers. The area of reliability evaluation of HVDC transmission systems has not attracted much attention in the past. The situation is changing as more and more

Software Reliability Evaluation of Digital Relaying for Power Transmission Lines
Electric Power Components and Systems, 2009Abstract A digital relay can be conceived as a digital signal processor in which the values of line currents and voltages are continuously monitored and processed. Hence, the heart of the digital relay is the software used for implementing the relaying algorithms in an efficient way.

Facts for enhancing the reliability of power transmission grids
3rd IEE International Conference on Reliability of Transmission and Distribution Networks (RTDN 2005), 2005Recent blackouts have focused on the critical importance of secure and reliable power supply. Traditionally the strengthening of power grids has involved the construction of new transmission lines, usually at considerable cost and in the face of substantial public objections.
