Abstract: FIELD: power stations. 
     SUBSTANCE: upon load disconnection from supply mains load and supply mains voltages are checked and phase difference is determined. Variation in phase difference is approximated by two values of load and supply mains voltages. Time moment when phase difference approaches desired value is calculated. ON-operation time of stand-by bushing circuit breaker is subtracted from values obtained. Least positive time difference is assumed as time delay in sending instruction for closing stand-by circuit breaker. This minimizes inrush currents during switch-over operations. In addition closing time of given circuit breaker is measured each time and measurement results are entered in memory for use during next ON-operation. 
     EFFECT: enhanced reliability.

Abstract: Изобретение относится к автоматике электрических сетей и может быть использовано для восстановления питания потребителей резервируемого участка линии по исходной схеме. В способе восстановлениия питания потребителей контролируют восстановление номинального напряжения со стороны основного источника питания резервируемого участка, фиксируют его восстановление. На резервируемом участке со стороны секционирующего выключателя через дополнительное сопротивление создают искусственное замыкание на землю с заданной продолжительностью, контролируют появление напряжения нулевой последовательности на резервируемом участке со стороны выключателя пункта автоматического включения резерва (АВР). При его появлении начинают отсчет времени, равного заданному времени искусственно созданного замыкания на землю. Если в момент окончания отсчета времени напряжение нулевой последовательности на резервируемом участке линии исчезает, то делают вывод, что замыкание на землю создано искусственно. Отключают выключатель пункта АВР, через который питаются потребители резервируемого участка по схеме резервного питания. Контролируют исчезновение всех линейных напряжений на резервируемом участке со стороны секционирующего выключателя. При исчезновении линейных напряжений делают вывод, что выключатель пункта АВР отключен и включают секционирующий выключатель для восстановления питания потребителей резервируемого участка по исходной схеме. В результате расширяются область применения и функциональные возможности способа, так как обеспечивается восстановление питания потребителей резервируемого участка линии по исходной схеме. 2 ил.
