Problems solved by technology

These types of energy storage components also add significantly to the cost of the delivery system
In addition, in this case the energy storage components also have very large dimensions in their mechanical dimension, in which case it is difficult to place them as part of the power supply system of the transmission system

Embodiment Construction

[0029] figure 1A control device according to the invention is represented, wherein power is supplied via a supply circuit 5 of the electric motor between the electric motor 2 of the mobile conveying apparatus 3 and the electrical network 4 . The power supply circuit 5 includes at least one controllable switch for controlling the power supply. In this case, in response to the movement reference 10 of the delivery instrument, the control part 9 which controls the movement of the delivery instrument adjusts at least one electrical parameter of the power supply circuit so as to move the delivery instrument.

[0030] In connection with the supply circuit of the electric motor, an energy storage element 6 whose capacity is limited (Elim) is also installed for supplying power between the energy storage element and the supply circuit 5 of the electric motor. The energy storage component 6 includes a plurality of ultracapacitors connected in series with each other.

Abstract

The object of the invention is a control arrangement of a transport system and a method in connection with a transport system. The transport system comprises a motor (2) for moving the transport appliance; a power supply circuit (5) of the motor, said power supply circuit being connected between the motor and a power source (4) that is limited (Plim) in its dimensioning; an energy storage that is limited (Elim) in its capacity fitted in connection with the power supply circuit of the motor, for supplying power between the energy storage and the power supply circuit (5) of the motor. The control arrangement comprises a determination (7) of the charging status (EQ) of the energy storage; a determination (8) of the movement reference of the transport appliance; and also a control (9) of the movement of the transport appliance as a response to the determined movement reference (10) of the transport appliance. The movement reference (10) of the transport appliance is determined on the basis of the amount of energy that can be discharged from the energy storage (6) and / or on the basis of the amount of energy that can be charged into the energy storage as well as on the basis of the travel distance (11, 11') of the transport appliance.

Description

technical field [0001] The object of the invention is a control device for a conveying system as defined in the preamble of claim 1 and a method relating to a conveying system as defined in the preamble of claim 6 . Background technique [0002] The power requirements of the conveying system vary according to the load and control conditions. For example, the power demand during acceleration of an elevator system is instantaneously more than twice the power required by the elevator system during constant speed. In this case, the current drawn by the elevator from the building's supply network also varies, and dimensioning, for example, of fuses in the building's power supply, has to be done according to the elevator's maximum supply current. During regenerative operation of the elevator motor, the elevator also returns some committed energy to the system. This energy returned to the power supply system is usually converted into heat in a separate power resistor or it is ret...
