Description
пилообразный генератор, с выхода которого на узел 11 поступает сигнал о времени экстрапол ции от О до Г в каждом цикле. Величина максимального времени экстрапол ции выбираетс исход из веро тностных характеристик конкретного перетока. Узел блокировки пропускает входной сигнал (АРп ) на оператор экстрапол ции 13 в начальный момент экстрапол ции ( 0) и держит его посто нным в течение всего цикла (). Оператор экстрапол ции имеет следующий вид: -13 е -л - f-Rt- i АР по + АРл (t) а-р rfAPno где АР по - отклонение фактического значени перетока от заданного в начальный момент экстрапол ции; АРп (О - экстраполированное на интервал времени t значение отклонени перетока АРп при фиксированном АР по ; а, р - коэффициенты, определ емые в результате статистической обработки случайных колебаний перетока . Максимально возможное в течение одного цикла (О-Т) экстраполированное значение АРп макс поступает на усилитель 14, где суммируетс с заданным значением перетока Р пзад. Максимально возможное значение полного перетока мощности Рпмакс с выхода усилител 14 поступает на блок сравнени 15, где сравниваетс с допустимым по соображени м устойчивости или перегрузки значением перетока Рпдоп . Если Рпмакс РПДОП , то с выхода блока сравнени поступаетдеблокиру заa sawtooth generator, from which output to node 11 receives a signal about the extrapolation time from O to D in each cycle. The magnitude of the maximum extrapolation time is selected based on the probability characteristics of the particular flow. The blocking node passes the input signal (ARP) to the extrapolation operator 13 at the initial moment of extrapolation (0) and keeps it constant during the whole cycle (). The extrapolation operator is as follows: -13 e-f-Rt-i AR by + ARL (t) a r p rfAPno where AP by is the deviation of the actual value of the overflow from the extrapolation specified at the initial moment; ARP (O is the value of the deviation of the ARP flow extrapolated for the time interval t with a fixed AP over; a, p are the coefficients determined as a result of statistical processing of random flow oscillations. The maximum extrapolated ARP value during a single cycle (OT) to the amplifier 14, where it is summed up with the set value of the overflow P. Pzad. The maximum possible value of the total power flow Rpmax from the output of the amplifier 14 goes to the comparison unit 15, where it is compared with the allowable Resistant overload or overflow Rpdop value. If Rpmaks RPDOP then comparing the output with a block of postupaetdeblokiru
