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
