Description

Изобретение относится к железнодорожному транспорту, а более точно - к тяговому подвижному составу железных дорог.The invention relates to railway transport, and more specifically to a traction rolling stock of railways.

Известен способ управления энергетической эффективностью локомотива при работе с неполной нагрузкой путем изменения числа одновременно работающих тяговых двигателей (см., например, статью Пырова А.Е. «Современные системы управления электровозами» в журнале «Железнодорожный транспорт» №2, 2005, с. 64-66).There is a method of controlling the energy efficiency of a locomotive when operating at part load by changing the number of simultaneously operating traction engines (see, for example, A. Pyrova's article “Modern electric locomotive control systems” in the journal “Railway Transport” No. 2, 2005, p. 64 -66).

Данный способ выбран в качестве прототипа. Недостатком прототипа является то, что для управления энергетической эффективностью локомотива при работе с неполной нагрузкой изменение числа одновременно работающих тяговых двигателей осуществляется из кабины машиниста вручную.This method is selected as a prototype. The disadvantage of the prototype is that to control the energy efficiency of the locomotive when working with partial load, the change in the number of simultaneously operating traction motors is carried out manually from the driver’s cab.

Технической задачей настоящего изобретения является устранение указанного недостатка в разработанном способе управления энергетической эффективностью локомотива при работе с неполной нагрузкой.The technical task of the present invention is to remedy this drawback in the developed method for controlling the energy efficiency of a locomotive when operating with a partial load.

Решение данной технической задачи достигается тем, что в предлагаемом способе управления энергетической эффективностью локомотива при работе с неполной нагрузкой отключение или подключение тяговых двигателей происходит автоматически в соответствии с закономерностью, представленной в форме функциональной зависимости эксплуатационного коэффициента полезного действия локомотива η от коэффициента использования мощности γ вида

, где k1 и k2 – коэффициенты, определяемые в ходе тягово-энергетических испытаний локомотива, введенные в программу бортового компьютера локомотива, определяющей минимально достаточное число работающих тяговых двигателей, что обеспечивает увеличение коэффициента использования мощности и тем самым повышение значения коэффициента полезного действия (КПД) локомотива до уровня, близкого к номинальному.The solution to this technical problem is achieved by the fact that in the proposed method for controlling the energy efficiency of a locomotive when operating with partial load, the traction motors are switched off or connected automatically in accordance with the regularity presented in the form of a functional dependence of the operational efficiency of the locomotive η on the power utilization factor γ of the form
Figure 00000001
, where k 1 and k 2 are the coefficients determined during the traction and energy tests of the locomotive, entered into the program of the on-board computer of the locomotive, which determines the minimum sufficient number of working traction engines, which ensures an increase in the power utilization factor and thereby increase the value of the efficiency factor (Efficiency ) locomotive to a level close to the nominal.

Графическая часть описания изобретения содержит зависимость η=γ/(k1⋅γ+k2), представленную на фиг. 1.The graphic part of the description of the invention contains the dependence η = γ / (k 1 ⋅ γ + k 2 ) shown in FIG. one.

Не ограничивая общности, рассмотрим пример практической реализации данного способа управления энергетической эффективностью локомотива при работе с неполной нагрузкой.Without loss of generality, we consider an example of the practical implementation of this method of controlling the energy efficiency of a locomotive when operating with a partial load.

Число тяговых двигателей локомотива в общем случае обозначим как NΣ (фиг. 1), в данном конкретном примере для определенности примем NΣ=8. Номинальную мощность одного тягового двигателя обозначим как PТЭД. Тогда полная номинальная мощность локомотива составит РΣ=NΣ⋅PТЭД.The number of locomotive traction engines in the general case is denoted as N Σ (Fig. 1), in this particular example we will take N Σ = 8 for definiteness. The rated power of one traction engine is denoted by P TED . Then the full rated power of the locomotive will be P Σ = N Σ ⋅P TED .

Предположим, что в некоторый момент времени мощность, фактически затрачиваемая локомотивом на тягу при работе всех двигателей, составляет РФ=γΣ⋅PΣ, где γΣ - коэффициент использования мощности (КИМ) локомотива. В соответствии с фиг. 1 γΣ=ОА1. Этому режиму соответствует эксплуатационный КПД локомотива ηΣ=А1А.Suppose that at some point in time the power actually spent by the locomotive on traction during the operation of all engines is P Ф = γ Σ ⋅ P Σ , where γ Σ is the power utilization factor (CIM) of the locomotive. In accordance with FIG. 1 γ Σ = OA 1 . This mode corresponds to the operational efficiency of the locomotive η Σ = A 1 A.

При использовании заявляемого способа управления энергетической эффективностью локомотива при работе с неполной нагрузкой программа бортового компьютера в соответствии с зависимостью η=γ/(k1⋅γ+k2) определяет минимально достаточное число работающих тяговых двигателей (фиг. 1), это число равно двум, Nmin=2, и отключает остальные тяговые двигатели. В этом случае мощность локомотива составит Pmin=Nmin⋅PТЭД.When using the proposed method for controlling the energy efficiency of a locomotive when operating with partial load, the on-board computer program in accordance with the dependence η = γ / (k 1 ⋅ γ + k 2 ) determines the minimum sufficient number of working traction engines (Fig. 1), this number is two , N min = 2, and turns off the remaining traction motors. In this case, the locomotive power will be P min = N min ⋅ P TED .

Значение КИМ в данном режиме, при работе двух тяговых двигателей, составит γmin=ОВ1, а эксплуатационный КПД локомотива будет равен η=В1В.The CMM value in this mode, when two traction engines are running, will be γ min = ОВ 1 , and the operational efficiency of the locomotive will be η = В 1 V.

При использовании заявленного способа увеличение эксплуатационного КПД локомотива составит (фиг. 1) Δη=η-ηΣ=В1В-А1А, что принесет значительный экономический эффект.When using the inventive method, an increase in the operational efficiency of the locomotive will be (Fig. 1) Δ η = η-η Σ = B 1 B-A 1 A, which will bring a significant economic effect.

По сравнению с прототипом заявляемый способ позволяет адаптивно автоматически управлять энергетической эффективностью локомотива при работе с неполной нагрузкой. Повышается эксплуатационный КПД локомотива, снижаются затраты энергии на тягу поездов. Автоматический адаптивный режим управления позволяет обеспечить быстроту и точность управления энергетической эффективностью локомотива, что дает значительный экономический эффект и исключает ошибки, возможные при ручном управлении из кабины машиниста.Compared with the prototype of the inventive method allows adaptively automatically control the energy efficiency of the locomotive when working with partial load. The operational efficiency of the locomotive is increased, energy costs for traction are reduced. Automatic adaptive control mode allows you to ensure the speed and accuracy of energy management of the locomotive, which gives a significant economic effect and eliminates errors that are possible with manual control from the driver’s cab.
