Description

(54) СПОСОБ УПРАВЛЕНИЯ ВОЗБУЖДЕНИЕМ СИНХРОННОГО ГЕНЕРАТОРА(54) METHOD OF MANAGING THE EXCITATION OF A SYNCHRONOUS GENERATOR

Изобретение касаетс  управлени  электромеханическими переходными процессами в энергосистемах и может быть использовано д.т  управлени  возбуждением синхронных генераторов электрических станций.The invention relates to the control of electromechanical transients in power systems and can be used to control the excitation of synchronous generators of power plants.

Известны способы управлени  возбуждением синхронных генераторов, в которых дл  стабилизации электромеханических колебаний используют сигналы отклонени  и первой производной частоты напр жени  генератора 1 и 2.Methods are known for controlling the excitation of synchronous generators in which the deviation signals and the first derivative of the voltage of the generator 1 and 2 are used to stabilize electromechanical oscillations.

Однако дл  этих способов характерна недостаточна  эффективность электромеханических колебаний .при работе электростанции на соизмеримую по мощности приемную систему, а также в сложной энергосистеме при значительном изменении режимов ее работы.However, these methods are characterized by insufficient efficiency of electromechanical oscillations. When the power plant is operating on a receiving system that is comparable in power, as well as in a complex power system, with a significant change in its operating modes.

Известен также способ управлени  возбуждением синхронного генератора, в котором управление осуществл етс  по отклонению первой производной стабилизирующего сигнала, завис щего от частоты генератора, частот приемных систем и первой производной напр жени  генератора 3.There is also known a method for controlling the excitation of a synchronous generator, in which the control is carried out by the deviation of the first derivative of the stabilizing signal, depending on the frequency of the generator, the frequencies of the receiving systems and the first derivative voltage of the generator 3.

Однако оптимальные значени  настроечных коэффициентов стабилизирующего параметра не охватывают всего диапазона изменени  режима энергосистемы и не обеспечиваетс  достаточно эффективное демпфирование электромеханических колебаний.However, the optimal values of the tuning coefficients of the stabilizing parameter do not cover the entire range of variation of the power system mode and the electromechanical oscillations are not sufficiently damped.

Дл  расщирени  области интенсивного демп фировани  электротехнических колебаний по предложенному способу управлени  возбуждением синхронного генератора по отклонению и первой производной стабилизирующего сигнала , завис щего от частоты генератора, частот приемных систем и первой производной напр жени  генератора, измер ют разность частот регулируемой станции и одной,из приемных систем, замер ют активные мощности станции и отход щей линии, св зывающей соответствующую приемную систему с регулируемой станцией, определ ют сумму указанных активных мощностей в заданной пропорции, умножают разность частот на упом нутую сумму активных мощностей и полученный сигнал используют в качестве дополнительной составл ющей стабилизирующего сигнала.In order to clear the region of intensive damping of electrical oscillations by the proposed method of controlling the excitation of a synchronous generator by the deviation and the first derivative of the stabilizing signal, depending on the generator frequency, the frequencies of the receiving systems and the first derivative of the generator voltage, one of the receiving stations is measured systems, measuring the active powers of the station and the outgoing line connecting the corresponding receiving system with the controlled station, determine the sum of of the indicated active powers in a given proportion, multiply the frequency difference by the said sum of active powers and the received signal is used as an additional component of the stabilizing signal.

Структура стабилизирующего сигнала имеет следующий вид:The structure of the stabilizing signal has the following form:

П ,(Р, + &Ч) (f ,) --cU (1) где а с - псхто нные коэффиппенты;P, (P, + & H) (f,) --cU (1) where a c is the psychological coefficients;

Р; - активна  моц.ность pi, улируемой станции;R; - mobility of pi, lined station is active;
