Abstract
1. Способ выявления источника синхронных колебаний в эксплуатационном режиме работы энергосистемы, заключающийся в том, что для каждого генератора измеряют мгновенные значения фазных напряжений и токов; затем с заданной периодичностью вычисляют параметры электрического режима: действующее значение напряжения и реактивную мощность, вычисляют разность фаз между колебаниями реактивной мощности и колебаниями действующего значения напряжения и выявляют генератор, являющийся источником колебаний, если у него колебания реактивной мощности и колебания действующего значения напряжения синфазны или колебания реактивной мощности опережают по фазе колебания действующего значения напряжения на величину не более заданной.2. Способ по п.1, отличающийся тем, что выявляют генератор, являющийся источником межмашинных колебаний генераторов одной электростанции по минимальной величине разности фаз колебаний реактивной мощности и колебаний действующего значения напряжения.1. A method for identifying a source of synchronous oscillations in the operating mode of the power system, which consists in the fact that for each generator measure the instantaneous values of phase voltages and currents; then, with a given periodicity, the electric mode parameters are calculated: the actual voltage value and reactive power, the phase difference between the reactive power fluctuations and the fluctuations of the effective voltage value is calculated, and the generator is detected, which is the source of oscillations if it has reactive power fluctuations and fluctuations in the effective voltage value in phase or oscillations reactive power is outpaced in phase by the fluctuations of the effective voltage value by an amount not exceeding a given value. 2. The method according to claim 1, characterized in that the generator is detected, which is the source of inter-machine oscillations of the generators of one power plant by the minimum value of the phase difference of the reactive power oscillations and the fluctuations of the actual voltage value.
