“…Although calculations of reliability parameters in the energy sector have been conducted for a long time [1][2][3][4], there are relatively few scientific papers devoted particularly to the assessment of the structural and balance reliability of electricity and energy supply by the DG units [5][6][7][8][9][10]. The publications are aimed primarily at improving the computation techniques and not the reliability factor application itself.…”

The paper considers the reliability level of different distributed generation units. The world comparative statistics of reliability parameters depending on the unit capacity and other influencing factors are presented. The study includes an analysis of possible approaches to the correction of statistical parameters under the particular conditions. The calculation and analysis of structural reliability parameters for a group of distributed generation units is performed. It is shown that conventional N+1 reliability principle is not enough for distributed generation given a great number of operation conditions. A set of N+n principles is proposed according to the required distributed generation reliability level. Considering the reliability parameters is of great importance for the selection of installed power and the structure of distributed generation for industrial and household facilities under the design and evaluation of its technical and economic efficiency. Gradual growth of the share of distributed generation in power and energy balances of power systems raises the issue of its reliability calculation and regulation. The results obtained in the paper are also important for the maintenance, planning of repairs, and providing necessary logistics solution for the delivery of spare parts and consumables to generating plants.

“…The evaluation of substation reliability is based on analysis of its electrical diagrams and of the impact of its emergency regimes on the operational reliability of the whole EPS [1][2][3][4][5][6][7][8][9][10][11][12]. The development of EPS and the renovation of its primary and secondary equipment cause changes in the reliability factors of some substations and, as a result, of the whole EPS.…”

“…The development of EPS and the renovation of its primary and secondary equipment cause changes in the reliability factors of some substations and, as a result, of the whole EPS. Therefore, the reliability evaluation of existing substations is a topical problem of practical importance [1][2][3][4][5][6][7][8].…”

Substation reliability is always a topical problem. The authors consider the techniques for reliability calculation based on logical-probabilistic approach to the evaluation of electrical substation switchgear schemes and equipment at emergency situations with disconnections of individual elements of the substation equipment or false operation of relay protection and automation devices. Based on the reliability analysis made for the 330kV substations of Latvian Electric Power System, recommendations are given concerning the reconstruction of switchgear schemes for some substations.
