This paper describes the implementation of reliability calculations into the routine network planning of a distribution network operator. Firstly, actual developments putting this issue on the agenda are described. Then, it is argued why medium voltage (MV) networks form the logical starting point. Hereafter, the basics of reliability calculations and the approach towards reliability calculations, as it is implemented in the MV network analysis program Vision, are elaborated upon. Finally, the practical implementation and applicability of reliability calculations is discussed. It is argued that the results of reliability calculations must be interpreted carefully, but that they can nevertheless be of good use in specific situations.

“…Many studies have been conducted on hidden failures in protective relays and their impact on power system reliability [9][10][11][12][13][14][15]. In [12], the definitions of 'vulnerability' and 'reliability of protection system' were provided to characterize numerically the impact of hidden protection failures on power system reliability.…”

Protection system failures are the main causes of cascading outages. There is a need to evaluate reliability indices, yet the effects of relay coordination methods have not yet been investigated in the existing literature. In this paper, an algorithm based on sequential Monte Carlo simulation is proposed to find the reliability indices for different overcurrent relay coordination methods. The proposed algorithm is applied to the results of three different relay coordination methods of a sample network. Then the reliability indices for the results of three different relay coordination methods are compared, and it is shown how the reliability indices are affected by the results of relay coordination methods.

“…In some of other published papers, the effects of protection system failures are concerned only with substations reliability assessment, and their impacts on network reliability indices are not considered [5][6][7]. Attempts have been made to consider the impacts of protection systems on network reliability in References [1,8,9]. Only one failure mode of protection systems is considered in References [1,9].…”

SUMMARYTransmission network reliability evaluation considering effects of protective systems is investigated in this paper. Protective system faults are one of the main sources of cascading outages and may lead to vast blackouts. Desired performance of the protection system has a significant role in the improvement of network reliability. The proposed method is based on minimal cutset approach. In the proposed method, all elements of the transmission and subtransmission substations can be considered in which subtransmission substations are taken as output nodes. A sensitivity analysis of network reliability to component reliability parameters is performed. Finally the effectiveness of the method was tested in a real network with satisfactory results.
