Embodiment 1

[0152] Such as Figure 1 to Figure 8 As shown, this embodiment discloses a method for controlling the load uniformity of equipment groups with periodic changes in operating power. The control system includes a data acquisition module 1, a data processing module 2 and an operation control module 3. In this embodiment, the type of power is electric power, and the method includes the following steps:

[0153] S1: Initialize the equipment group and calculation parameters:

[0154] Send the inherent power characteristics and single-cycle inherent capacity of each device collected by the data acquisition module to the data processing module, or directly input the known inherent power characteristics and single-cycle inherent capacity of each device into the data processing module;

[0155] Set the interruptible information of each device. The interruptible information includes the number of interruptible points of the device, the duration of the interruptible time, and the standby...

Embodiment 2

[0277] The difference between this embodiment and Embodiment 1 is that: in this embodiment, the type of power is thermal power; the optimization goal is to minimize the reduction in production capacity. Correspondingly, step SM25: delete the alternative optimization schemes in the set of alternative optimization schemes that do not satisfy the optimization objective:

[0278] For each of the remaining alternative optimization schemes in the set of alternative optimization schemes, the following calculation process of the capacity reduction rate is performed, that is, within the time length of one group cycle, two devices perform the adjustment method stored in the alternative optimization scheme. Compared with the total production capacity of the two devices without adjustment, the reduction degree of production capacity, that is, after adjustment, will make the power uniform, but it is likely to reduce the production capacity per unit time, and the production capacity reductio...

Abstract

The invention discloses a load homogenization control method and system for device groups with the periodically-varied running power. When the device groups with the periodically-varied power run, thevariation amplitude of a total power load is reduced, homogenization of the total power load is achieved, impact to an energy supply system is reduced, and through the capacity of the energy supply system, damage of the energy supply system is reduced, and energy consumption and the cost are reduced. The control method includes the following steps that S1, the device groups and calculation parameters are initialized; S2, a first device in a temporary device group is arranged; S3, a second device in the temporary device group is arranged; S4, an adjustment-power-characteristic set of the two devices is calculated; S5, a final optimization scheme and an optimal strategy set of the temporary device group are obtained; S6, new temporary device groups are formed for iteration looping; S7, an optimal strategy set is obtained; S8, the device groups are controlled to run. The control system comprises a data collecting module, a data processing module and a running control module. The load homogenization control method and system can be widely applied to the field of device controlling.

Description

technical field [0001] The invention relates to a load equalization control method when a plurality of equipments run simultaneously; the invention also relates to a load equalization control system when a plurality of equipments run simultaneously. Background technique [0002] In industrial production, equipment such as injection molding machines, molding machines, and placement machines have the characteristics of periodic changes in electrical power or / and thermal power. When a large number of similar equipment (that is, equipment groups) are running at the same time, if the working rhythm is not properly arranged, the power will appear at a maximum value at a certain point or time period, and a minimum value at a certain point or time period. This phenomenon is especially obvious for equipment groups composed of equipment of the same model and the same production process. This phenomenon will not only cause a great impact on the energy supply (such as power supply, hea...
